Risk Management
Hilary Till Until recently, one could only gain expertise in commodity-derivatives relationships if one had worked in niche commodity-processor companies or in banks that specialised in hedging project risk for natural-resource companies. The contribution of this article is to help fill the knowledge gap in the risk management of commodity derivatives trading. The article emphasises the constant challenges to a trader when attempting to navigate the very dynamic flows of both the commodity markets and the prevailing risk environment. The article also emphasises that operational controls are paramount in an age of increasing legal and regulatory risk, particularly for firms involved in large-scale commodity derivatives trading.

Portfolio Management
Victor DeMiguel, Francisco J. Nogales, Raman Uppal This paper first shows that a vector autoregressive (VAR) model captures daily stock return serial dependence in a statistically significant manner. Second, it characterizes (analytically and empirically) the expected return of an arbitrage (zero-cost) portfolio based on the VAR model, and shows that it compares favourably to that of other arbitrage portfolios in the literature. Third, it evaluates three investment (positive-cost) portfolios: a conditional mean-variance myopic portfolio obtained using the linear VAR model; a conditional mean-variance portfolio using a nonparametric autoregressive (NAR) model; and, a portfolio that is dynamic rather than myopic in its use of the VAR model. All three investment portfolios have similar performance, and they substantially outperform the traditional (unconditional) mean-variance portfolio, which ignores serial dependence in stock returns. Finally, the paper finds that the portfolios exploiting stock return serial dependence have very high portfolio turnover, and shows how a norm-constraint on portfolio weights can be used to reduce their turnover, while still outperforming the traditional (unconditional) portfolios.

Exchange-Traded Funds
Nöel Amenc, Frédéric Ducoulombier, Felix Goltz, Lin Tang This paper outlines EDHEC-Risk Institute's positions on the major concerns of counterparty risk, liquidity risk, confusion between ETFs and other ETPs, risks associated with special types of ETFs, and potential impact of ETFs on the underlying markets and systemic risks. The focus is solely on European ETFs, the bulk of which are regulated by UCITS Directives. Prior to looking at the potential risks of ETFs, the paper presents ETFs and sizes-up the European ETF landscape. More...

Alternative Investments
Mathieu Vaissié There is growing empirical evidence that the complexity of financial markets makes it increasingly challenging for institutional investors to manage their asset/liability profile efficiently. Changes in the regulatory framework and in accounting rules make it even trickier for insurance companies. Against this backdrop, insurers have no choice but to rethink their overall investment policy. More...

Risk Management
Stoyan V. Stoyanov, Svetlozar T. Rachev, Frank J. Fabozzi Risk management through marginal rebalancing is important for institutional investors due to the size of their portfolios. This paper considers the problem of marginally improving portfolio VaR and CVaR through a marginal change in the portfolio return characteristics. It studies the relative significance of standard deviation, mean, tail thickness, and skewness in a parametric setting
assuming a Student's t or a stable distribution for portfolio returns. More...

Credit Default Swaps
Dominic O’Kane This paper performs a theoretical and empirical analysis of the relationship between the price of Eurozone sovereign-linked credit default swaps (CDS) and the same sovereign bond markets during the Eurozone debt crisis of 2009-2011. It first presents a simple model which establishes the no-arbitrage relationship between CDS and bond yield spreads. It then tests this relationship empirically and explains why the market may deviate from it. Reasons include the different currencies of denomination of market-standard CDS and their reference obligations. It also examines whether CDS spread cause changes in bond spreads, and vice-versa, in a Granger sense. It finds evidence for a Granger causal relationship with a one day lag from CDS to bonds for
Greece and Spain, the reverse relationship for France and Italy and a feedback relationship for Ireland and Portugal. More...

Asset Allocation and Alternative Diversification
Stoyan Stoyanov This publication show that a structured target-volatility strategy significantly improves both the downside and the upside of the return distribution relative to a fixed-mix strategy and also allows investors to benefit more from the upside potential when a capital guarantee overlay is applied. It shows how the explicit management of volatility reduces the cost of the capital protection. It also documents utility gains for risk-averse investors, with and without capital guarantee overlay, and makes the case for significant allocations to structured equity investment strategies with volatility targeting.

Risk
Noël Amenc, Lionel Martellini, Felix Goltz, Dev Sahoo This paper analyses the relationship between risk and expected returns in the cross section of US stocks, using various total and idiosyncratic risk measures, as well as various holding periods. Our main finding is that the investment horizon has a strong influence on the risk-return relationship. In particular, the so-called “iv puzzle”, stating that high idiosyncratic volatility stocks have low returns (Ang, Hodrick, Ying, and Zhang (2006, 2009)), disappears for holding periods greater than one year. More generally, we confirm that the risk-return trade-off is exactly what theory predicts over long horizons – holding stocks with high volatility, high Value-at-Risk (VaR), high semi-deviation, low skewness or high kurtosis mostly leads to higher returns compared to holding their low-risk counterparts. These results are robust with respect to a number of methodological choices and multivariate controls. More...

Private Wealth Management
Romain Deguest, Lionel Martellini, Vincent Milhau This paper argues that financial innovation is needed to design better target date funds based on stochastic life cycle investing, taking into account the presence of risk factors that impact not only asset returns, but also private investors’ wealth levels. One key element in private wealth management is the presence of income risk, which has a substantial impact on the optimal asset allocation strategy. More...

Commodities
Joëlle Miffre A number of policy-makers have blamed the decade-long rise in commodity prices and recent market volatility on the growing influence of financial investors and called for new regulation restricting their participation in commodity markets. Market financialisation has also led investors to worry about higher integration between commodity and traditional financial markets weakening the portfolio benefits of commodity investment. This study, produced with market data and support from CME Group, first examines the performance and risk characteristics of long-only commodity index investments favoured by passive investors and of long/short commodity strategies of the kind implemented by hedge fund managers.

Regulation
Noël Amenc, Samuel Sender Several regulatory initiatives are being taken in Europe and recommendations that will reshape the investment fund industry are being made. Existing regulations, such as UCITS, are being reshaped; the need for a regulation of depositaries has been acknowledged, and since the G20 there has been more focus on the monitoring of hedge funds. Many of these regulatory needs have converged in the alternative investment fund managers’ directive (AIFMD), which means that the AIFMD could become a unique framework that settles most of the questions related to the common framework for funds, fund managers and depositaries. However, it must avoid the risk of the AIFMD not being applicable if it appears as a patchwork of diverging goals that have been grouped into a single directive solely for political reasons. The present position paper addresses the
measures for implementation of the AIFMD. More...

Indexes & Benchmarking
Noël Amenc, Felix Goltz, Lin Tang As the choice of an index is a crucial step in both asset allocation and performance measurements, it is useful to investigate index use and perceptions about indices.

Socially Responsible Investment
Véronique Le Sourd This paper conducts a performance measurement of SRI funds and assesses the impact of changing the reference from a standard SRI index to an efficient SRI index. The analysis of fund performance shows that an efficient SRI index raises the bar for actively managed SRI funds. While about 60% of funds have a positive information ratio when compared to the cap-weighted EuroStoxx Sustainability Index, only about 25% of funds do so with respect to the Efficient SRI Index. It is also interesting to note that the median information ratio across funds is slightly positive (0.05) when using the standard SRI index, but it is clearly negative (-0.22) when using the Efficient SRI index.

Performance
Victor DeMiguel, Yuliya Plyakha, Raman Uppal, Grigory Vilkov The objective of this paper is to examine whether one can use option-implied information to improve the selection of portfolios with a large number of stocks, and to document which aspects of option-implied information are most useful for improving their out-of-sample performance. Portfolio performance is measured in terms of four metrics: volatility, Sharpe ratio, certainty-equivalent return and turnover. More...

Portfolio Management
François-Serge Lhabitant Two common beliefs in finance are that (i) a high positive correlation signals assets moving in the same direction while a high negative correlation signals assets moving in opposite directions; and (ii) the mantra for diversification is to hold assets that are not highly correlated. This paper explains why both beliefs are not only factually incorrect, but can actually result in large losses in what are perceived to be well diversified portfolios. More...

Risk Management
Barry Schachter, S. Ramu Thiagarajan Mean-Variance optimisation has come under great criticism recently, based on the poor performance experienced by asset managers during the global financial crisis. In response, an alternative approach, called Risk Parity, which proceeds by equalising risk contributions, has garnered much interest. This paper summarises the work of a group of leading researchers on Risk Parity. More...

Risk Management
Stoyan V. Stoyanov This paper introduces a decomposition of a sub-class of spectral risk measures in terms of L-moments accounting for geometric characteristics of the return distribution similar to the ones described by the ordinary moments. The decomposition completely characterises the spectral risk measures with square-integrable risk aversion functions and can be regarded as a link between higher-order moment risk and downside risk measures. Coherent approximations based on only a few L-moments can be successfully constructed for continuous risk aversion functions and can be applied to problems in portfolio theory to analyse the incremental impact of higher order moments on optimal allocations.

Alternative Investments
Hilary Till, Joseph Eagleeye Managed futures strategies are a niche-within-a-niche in the capital markets. Despite this status, managed futures have become of particular interest to hedge fund investors. This paper discusses why this has become the case by focusing on this strategy’s unique diversification properties. It also briefly covers the main characteristics of this investment category, its underlying sources of return, and alternative statistical measures that are appropriate for comparing managed futures investments with hedge fund investments.

Risk Management
Georges Hübner, Marie Lambert This paper proposes an alternative way to construct the Fama and French (1993) empirical risk factors. Without losing in significance power, in beta consistency or in factor efficiency compared to the Fama and French factors, our technique insulates the effects of other sources of risk as much as possible when evaluating one risk factor.

Commodities
Hilary Till This paper examines food price volatility in the context of the G20 meeting of agriculture ministers. In reviewing the evidence so far regarding the impact of commodity trading, speculation, and index investment on price volatility, the report finds that the evidence for the prosecution does not seem particularly compelling at this point.

Regulation
Raman Uppal Almost each time volatility in equity, debt, or currency markets increases, there are cries to introduce a tax of financial transactions, first proposed in Tobin (1974). This tax is motivated by the view that the excess volatility in financial markets is the result of trading by "speculators"; thus, even a small tax on financial transactions would "throw some sand in the wheels" of financial markets, and hence, by slowing down the trading activity of speculators would reduce volatility.

Risk Management
Elie Charbit, Jean-René Giraud, Felix Goltz, Lin Tang There is extensive evidence that investment strategies based on momentum and value are attractive for portfolio managers who seek higher performances. Momentum and value are among the most robust return drivers in the cross section of expected returns. Dynamic risk budgeting methodologies such as Dynamic Core Satellite strategies (DCS) are used to provide risk-controlled exposure to different asset classes. We examine how to exploit the value and momentum anomalies using a DCS investment model. This paper shows that the DCS approach can boost portfolio returns while keeping downside risk under control. The implementation of the portfolio strategies is enabled by exchange-traded funds which are natural investment vehicles since they offer a broad exposure to the markets and provide the necessary liquidity to the frequent rebalancing of the DCS model.

Portfolio Management
Bernd Scherer Disappointed with the performance of market-weighted benchmark portfolios yet skeptical about the merits of active portfolio management, investors in recent years turned to alternative index definitions. Minimum variance investing is one of these popular rule driven, i.e. new passive concepts. This paper shows theoretically and empirically that the portfolio construction process behind minimum variance investing implicitly picks up risk-based pricing anomalies. In other words the minimum variance tends to hold low beta and low residual risk stocks. Long/short portfolios based on these characteristics have been associated in the empirical literature with risk-adjusted outperformance (alpha). This paper shows that 83% of the variation of the minimum variance portfolio excess returns (relative to a capitalization-weighted alternative) can be attributed to the FAMA/FRENCH factors as well as to the returns on two characteristic anomaly portfolios. All regression coefficients (factor exposures) are highly significant, stable over the estimation period and correspond remarkably well with our economic intuition. A revisited version of this paper was published in the September 2011 issue of the Journal of Empirical Finance. More...

Risk Management
Bernd Scherer Sovereign wealth funds (SWFs) typically have no direct earmarked liabilities. Nor should they, as the financial asset they represent is only part of total sovereign assets, which in turn guarantee all sovereign liabilities. The objective of this paper is to incorporate the economic balance sheet of the sovereign sponsor into the optimal asset allocation problem of the SWF. This paper outlines an easy to implement solution that nests well in the literature on SWFs. We show that economic leverage will reduce speculative demand but leave hedging demand (against fluctuations in the net fiscal position of the sovereign state) unchanged. We also show how to extend our one-period methodology to a multi-period context by solving a dynamic stochastic programme. More...

Alternative Investments
Stephen J. Brown, Greg N. Gregoriou, Razvan Pascalau Samuelson (1967) argues that as a general matter it is easy to show that investors should be maximally diversified. For this reason many institutions are attracted to diversified portfolios of hedge funds, referred to as Funds of Hedge Funds (FOFs). In this paper we examine a new database that separates out for the first time the effects of diversification (the number of underlying hedge funds) from scale (the magnitude of assets under management). We find with others that the variance reducing effects of diversification peter out once FOFs hold more than 20 underlying hedge funds. Yet the majority of FOFs are more diversified than this. We find a new and surprising result that this excess diversification actually increases the left tail risk exposure of FOFs particularly once we account for the extent to which hedge fund returns are smoothed. This paper is forthcoming in the Review of Asset Pricing Studies. More...

Portfolio Management
Daniel Giamouridis, Chris Montagu Valuation signals have been among the most popular with equity portfolio managers and have recently attracted significant interest from cross-asset managers. Given a large variation of techniques and theories with regard to how value is measured, this paper investigates the efficacy of alternative value measures. It considers a cross-section of simple and sophisticated alternative measures and focuses on comparison metrics that are of primary interest for equity portfolio managers. The results show that sophisticated valuation models—although not universally—are superior to simple valuation models in many respects. Thus, the paper concludes that sophisticated models have interesting attributes and in general should be considered an additional if not primary perspective on equity valuation and portfolio management.

Asset Pricing
Chris Brooks, Xiafei Li, Joëlle Miffre A vast body of literature has documented the value premium and the small firm effect as pervasive stylized facts in empirical asset pricing and yet research has been largely unable to provide entirely convincing explanations of these phenomena. This paper examines the role of idiosyncratic risk in explaining the cross-sectional variation of stock returns in the context of a set of size- and value-sorted portfolios. More...

Indexes & Benchmarking
Felix Goltz, Carlos Heitor Campani This paper analyses two sets of four corporate investment-grade bond indices each, one for the US market and the other for the euro-denominated bond market. First, we review the uses of bond indices as well as the challenges involved. We then analyse the risk-return properties and the heterogeneity of the indices in each set. Although the indices in each market resemble each other, there are still some differences. Moreover, an analysis of the stability of the indices’ risk exposures (interest rate and credit risks) reveals very unstable measures over time and, perhaps most importantly, this instability is accentuated in the two indices with the smallest number of bonds: the more investable the index is meant to be, the less reliable it is. Finally, we find great differences between US and euro-denominated indices: US corporate bond indices showed higher credit risk, with longer terms to maturity and hence longer durations. More...

ALM and Asset Management
Lionel Martellini, Vincent Milhau This paper provides a joint quantitative analysis of capital structure decisions
and debt structure decisions within a standard continuous-time capital-structure
model. In the presence of interest rate and inflation risks, we are able to obtain quasi-closed form expressions for the price of various forms of indexed- and non-indexed bonds issued by the firm, which allows us to generate computationally efficient estimates for the optimal debt structure. Our analysis shows that debt-structure decisions have a strong impact on capital structure decisions. It also suggests that substantial increases in firm value can be
generated by optimal debt structures. More...

Commodities
Devraj Basu, Joëlle Miffre This paper constructs factor-mimicking portfolios that capture the hedging-pressure-based risk premium of commodity futures. It considers single sorts based on the open interests of either hedgers or speculators, as well as double sorts based on both positions. It finds strong evidence for a risk premium arising from the combination of the two positions. Further tests show that the hedging pressure-based risk premium rises with the lagged volatility of commodity markets and that the cross-sectional price of commodity risk is positive. Our risk premium is also found to explain part of the performance of active portfolios based on momentum and/or term structure. More...

Risk
Noël Amenc, Felix Goltz, Stoyan Stoyanov Since the global financial crisis of 2008, improving risk management practices—management of extreme risks, in particular—has been a hot topic. The postmodern quantitative techniques suggested as extensions of mean-variance analysis, however, exploit diversification as a general method. Although diversification is most effective in extracting risk premia over reasonably long investment horizons and is a key component of sound risk management, it is ill-suited for loss control in severe market downturns. Hedging and insurance are better suited for loss control over short horizons. In particular, dynamic asset allocation techniques deal efficiently with general loss constraints because they preserve access to the upside. Diversification is still very useful in these strategies, as the performance of well-diversified building blocks helps finance the cost of insurance strategies. More...

Business Analysis
Ekkehart Boehmer, Julie Wu This paper shows that stock prices impound more information when short sellers are more active. First, in a large panel of NYSE-listed stocks, high-frequency informational efficiency of prices improves with greater daily shorting flow. Second, at monthly and annual horizons, more shorting flow accelerates the incorporation of public information into prices. Third, greater shorting flow reduces post-earnings announcement drift for negative earnings surprises. Fourth, we demonstrate that short sellers change their trading around extreme return events in a way that aids price discovery. These results are robust to various econometric methodologies and model specifications. Overall, the results highlight the important role that short sellers play in the price discovery process.

Risk
Ferhat Akbas, Ekkehart Boehmer, Egemen Genc, Ralitsa Petkova This paper studies the liquidity exposures of value and growth stocks over business cycles. In the worst times, value stocks have higher liquidity betas than in the best times, while the opposite holds for growth stocks. Small value stocks have higher liquidity exposures than small growth stocks in the worst times. Small growth stocks have higher liquidity exposures than small value stocks in the best times. The results are consistent with a flight-to-quality explanation for the countercyclical nature of the value premium. More...

Alternative Investments
Greg N. Gregoriou, François-Serge Lhabitant, Fabrice Douglas Rouah This paper attempts to determine whether exchange-listed hedge funds experience longer lifetimes than non-listed funds, even after factors known to affect survival, such as size and performance, are considered. The Kaplan-Meier estimator is used to compare survival times of listed and non-listed funds. The Cox proportional hazards model is used to make the same comparison, but by controlling for additional factors. The accelerated failure time (AFT) regression model is used to estimate the median survival time of hedge funds, based on values of explanatory variables. A revisited version of this paper was published in the December 2009 issue of the Journal of Applied Research in Accounting and Finance. More...

Real Estate
James Chong, Joëlle Miffre, Simon Stevenson This paper studies the temporal variations in the conditional correlations between REIT returns and equity, bond and commodity returns. While REITs are often presented as useful tools for diversification, little is known of the way their returns correlate with the returns of other asset classes over time and in periods of high volatility. This paper addresses this issue and draws two conclusions. First, the correlations between REITs and equity returns rose over the period analyzed, while the correlations with bonds and commodities fell. This indicates to equity portfolio managers that real estate has lost some of its diversification properties, but to bond and commodity portfolio managers it has become attractive for strategic asset allocation. Second, the correlations with REITs rose especially in periods of above average volatility in equity and bond markets. This is unfortunate as it is precisely in periods of high volatility that investors need the benefits of diversification the most. A revisited version of this paper was published in the April 2009 issue of the Journal of Real Estate Portfolio Management.

Derivatives
Rene Garcia, Daniel Mantilla-Garcia, Lionel Martellini Idiosyncratic volatility has received considerable attention is the recent financial literature. Whether average idiosyncratic volatility has recently risen, whether it is a good predictor for aggregate market returns and whether it has a positive relationship with expected returns in the cross-section are still matters of active debate. We revisit these questions from a novel perspective, by taking the cross-sectional variance of stock returns as a measure of average idiosyncratic
variance. More...

Institutional Investment
Samuel Sender EDHEC surveyed corporate pension funds, their sponsors, and advisers to assess how sponsors manage pension risk and how pension funds manage sponsor risk. There are 100 respondents to the survey; they manage pension funds assets of more than €730 billion (the assets of sponsoring companies are greater than €5.5 trillion). Sponsors that give their employees pension plans are subject to the risk of having to make additional contributions to make up for shortfalls in pension funds as well as to a more specific accounting risk that arises because of the arbitrary accounting assumptions that differ from those typical of financial economics.

Regulation
Paul Klumpes, Peter Welch This paper reviews the arguments for and against the decoupling of capital ratio calculations based on IFRS from those based on Basel II. We analyse recent trends in both accounting and regulatory supervision after the financial crisis and identify areas where there are still deficiencies in the transparency of IFRS-based financial reports and regulatory-based capital disclosures and calculations. We find that the variation in disclosure practices across IFRS and BIS-based capital estimations is significant for a sample of major European banks. More...

Asset Pricing
Lionel Martellini, Vincent Milhau This paper addresses the problem of option hedging and pricing when a futures contract, written either on the underlying asset or on some imperfectly correlated substitute for the underlying asset, is used in the dynamic replication of the option payoff. In the presence of unspanned basis risk modeled as a Brownian bridge process, which explicitly accounts for the convergence of the basis to zero as the futures contract approaches maturity, we are able to obtain an analytical expression for the optimal hedging strategy and corresponding option price. Empirical analysis suggests that the hedging demand against basis risk is an important ingredient of the hedging strategy. For reasonable parameter values, we also find the replication error implied by the optimal strategy to be substantially lower than that implied by heuristic strategies routinely used in practice.

Noël Amenc, Samuel Sender This publication looks at how non-financial
risks and failures have impacted the regulatory agenda in Europe and traces
the management of liquidity, counterparty, compliance, misinformation, and other financial risks in the fund industry. By identifying the distribution of risks and responsibilities in the industry, it examines how convergence between country regulations could be achieved. Finally, it assesses how fund unit-holders can best be protected with appropriate regulations, improved risk management practices, and greater transparency. More...

Private Equity
Florencio Lopez-de-Silanes, Ludovic Phalippou, Oliver Gottschalg This paper examines the determinants of private equity returns using a newly constructed worldwide database of 7,500 investments made over forty years. The median investment IRR (PME) is 21% (1.3), gross of fees. One in ten investments goes bankrupt, whereas one in four has an IRR above 50%. Only one in eight investments is held for less than two years, but such investments have the highest returns. The scale of private equity firms is a significant driver of returns: investments held at times of a high number of simultaneous investments underperform substantially. More...

Alternative Investment
Gideon Ozik, Ronnie Sadka This paper measures the differential impact of alternative media outlets. We classify news items about equity hedge funds over 1999 to 2008 into three source groups: General newspapers, Specialized magazines, and Corporate Communication. Applying a textual analysis to news items, we uncover three types of media biases. First, a reporting style bias, that is, when a fund is covered by multiple sources at the same time, the sentiment is most positive in Corporate coverage and least in General coverage. The differences in source sentiment are more significant in cases of exclusive coverage, indicating a second bias, editorial selection. Finally, examining post-coverage, sentiment-adjusted fund performance, we document that Corporate-covered funds outperform and General-covered funds underperform, with a performance difference of about 11% annually.

Socially Responsible Investment
Noël Amenc, Felix Goltz, Lin Tang This document reviews the concept of green investing and reports the results of a European survey of investment management professionals. The objective is to provide background on industry and academic research into green investing and assess the views and uses of green investing. Our survey shows that green investing is a significant movement in which survey respondents are heavily involved. Nearly 90% of respondents consider environmental protection an investment theme and the same percentage plans to do more green investing in the future. More...

Private Wealth Management
Noël Amenc, Sergio Focardi, Felix Goltz, David Schröder, Lin Tang A survey drawing on responses from 159 European private wealth managers, the three main findings of which are: Private wealth managers see the relationships they forge with their clients as the principle source of the value they add but they fail to exploit this close relationship to customise the services they offer their clients (when portfolios are designed for clients, market factors are taken into account more frequently than are the individual characteristics of the clients); Private wealth managers fail, on the whole, to provide state-of-the art means of horizon-dependent asset allocation. In fact, when human capital, the time and state dependency of investment opportunities, and other causes of horizon effects are not recognised, one can conclude that horizon-based allocations are approximate rather than optimal; Private wealth managers see the great potential of taking into account client-specific spending objectives, but only a small minority actually attempts to realise this potential.

Investable indices tend to recursively underperform their non-investable versions. In light of recent events, we can wonder whether the liquidity crisis that occurred in the wake of the Lehman collapse and had a significant impact on the performance of hedge fund strategies (more particularly on the strategies that are exposed to credit risk) has increased this excess return or not. In this respect, it would be interesting to compare the excess returns of non-investable indices and those of their investable counterparts before and after 2008. More...

Performance
Laetitia Drusch, Abraham Lioui We use a sample of 148 events related to corporate social responsibility (CSR) to assess the impact of CSR on corporate financial performance. There is considerable heterogeneity in market reaction to different dimensions of CSR. Not all dimensions offer a positive reward; some yield a negative and even statistically significant impact on the firms’ stock returns. One main conclusion of this study is that socially responsible investment is not an excuse for passive management. There is still room for timing and stock picking within the socially responsible universe of stocks. More...

Investment Management
Lionel Martellini, Vincent Milhau This paper proposes a quantitative dynamic asset allocation framework for sovereign wealth funds, modelled as large long-term investors that manage fluctuating revenues typically emanating from budget or trade surpluses in the presence of stochastic investment opportunity sets. The optimal asset allocation strategy takes into account the stochastic features of the sovereign fund endowment process (where the money is coming from), the stochastic features of the sovereign fund's expected liability value (what the money is going to be used for), and the stochastic features of the assets held in its portfolio.

Risk Management
Rodrigo Dupleich, Daniel Giamouridis, Chris Montagu This paper investigates the potential improvement in the implementation of style rotation strategies by techniques addressing estimation errors. We select two approaches that have recently stood out in the statistics and econometric literature and have been applied to portfolio construction literature. One builds on regularization methods which address estimation error by focusing on the weights of the constructed portfolios. And a second method that uses pooled forecasts obtained across different observation windows. Thus it focuses on minimizing estimation error in the moments of the return distribution that may arise due to structural breaks. We conclude that overall there are benefits from departing from naïve approaches which can be as significant as an improvement in the information ratio of about 54%, i.e., from 0.65 (naïve) to about 1 (dynamic). A revisited version of this paper was published in the Winter 2012 issue of the Journal of Portfolio Management. More...

Equity Markets
Ekkehart Boehmer, Sudheer Chava, Heather E. Tookes This paper examines how the existence of individual equity options, publicly traded corporate bonds and credit default swap (CDS) contracts affects equity market quality for a panel of NYSE-listed firms during 2003-2007. We find that firms with listed equity options have more liquid equity and more efficient stock prices. By contrast, firms with traded CDS contracts have less liquid equity
and less efficient stock prices, especially when these firms or their capital structures are complex (i.e., hard to value). The impact of having a publicly traded bond market is somewhat mixed; however, we observe a signicantly negative role for all trading activity in the related markets (i.e., in both bonds and options) for efficiency and liquidity. Taken together, these results imply an
overall negative effect of related markets when those markets are tied to debt in a firm's capital structure. More...

Paul Klumpes This paper explores the financial statement implications of alternative measurement bases underlying defined benefit pension accounting rules via a simulation analysis. Simulation analysis can be used to examine the effect of alternative discount rate assumptions on the strength of associations between an economic or generational accounting basis, an actuarial funding basis of measurement and two alternative accounting measurement bases of pension assets and liabilities; value-in-use and value-in-exchange. Accounting measures are found to be more highly correlated with economic unfunded pension liabilities when they are discounted using market instead of value in use rates. The value at use rates are also more highly sensitive to differences in funding method, real versus nominal interest rates and plan initiation dates. The findings suggest that the use of alternative measurement bases for pension reporting and funding involves a trade-off between the relevance and reliability of the resulting pension disclosures.

Risk Management
Frank J. Fabozzi, Sergio Focardi, Masao Fukushima, Dashan Huang, Zudi Lu, Baimin Yu Instead of assuming the distribution of return series, Engle and Manganelli (2004) propose a new Value-at-Risk (VaR) modeling approach, Conditional Autoregressive Value-at-Risk (CAViaR), to directly compute the quantile of an individual asset’s returns which performs better in many cases than those that invert a return distribution. This paper explores more flexible CAViaR models that allow VaR prediction to depend upon a richer information set involving returns on an index. Specifically, we formulate a time-varying CAViaR model whose parameters vary according to the evolution of the index. A revisited version of this paper was published in the March 2010 issue of Studies in Nonlinear Dynamics & Econometrics. More...

Asmerilda Hitaj, Lionel Martellini, Giovanni Zambruno Since hedge fund returns are not normally distributed, mean-variance optimisation techniques, which would lead to substantial welfare losses from the investor’s perspective, need to be replaced by optimisation procedures incorporating higher-order moments and comoments. In this context, optimal portfolio decisions involving hedge fund style allocation require not only estimates for covariance parameters but also estimates for coskewness and cokurtosis parameters. This is a formidable challenge that severely exacerbates the dimensionality problem already present with mean-variance analysis. This paper presents an application of the improved estimators for higher-order co-moment parameters, recently introduced by Martellini and Ziemann (2010), in the context of hedge fund portfolio optimisation.

Serge Darolles, Mathieu Vaissié In spite of a somewhat disappointing performance throughout the crisis, and a series of high-profile scandals, investors are showing interest in hedge funds. Still, funds of hedge funds keep on experiencing outflows. Can this phenomenon be explained by the failure of fund of hedge fund managers to deliver on their promise to add value through active management, or is it symptomatic of a move toward greater disintermediation in the hedge fund industry? Little attention has been paid so far to the added value, and the sources of the added value, of funds of hedge funds.

Lionel Martellini, Vincent Milhau In an attempt to address the concern over financially illiterate individuals being increasingly responsible for investment decisions related to retirement risk, the financial industry has started to design dedicated mutual fund products known as target date funds. These funds, whose aim is to provide investors with one-stop solutions to their life-cycle investment needs, typically propose a deterministic decrease of equity allocation until a date called the target date of the fund. This approach, however, has been found inconsistent with the prescriptions of standard life-cycle investment models (Viceira and Field 2007). A revisited version of this paper was published in the November-December 2010 issue of Bankers, Markets & Investors.

Four main weighting schemes are analysed: efficient indices, fundamental indices, minimum-volatility indices, and equal-weighted indices. Empirical results for US and Developed World data on these indices show that the average returns of all four alternative index construction methods are superior to those of cap-weighted equity indices in both universes and that, by several measures of risk-adjusted performance, they are likewise superior.

Abraham Lioui The ban on shorting had negative effects on the hedge fund industry. It also had a negative impact on the returns and the market quality of the stocks placed off limits by the ban. This paper examines the impact of the ban on broad market indices in the US and in Europe (the United Kingdom, France, and Germany). Since these indices and their performance are of great concern to the asset management and hedge fund industries, it is important for practitioners and policy-makers to understand the impact of changing the rules of the game (banning short sales) on the return distribution of these indices and to assess the potential spillover effects of a counter-cyclical regulation affecting only one segment of the financial market. The paper shows that the ban had a broad impact on the markets. A revisited version of this paper was published in the Winter 2011 issue of the Journal of Alternative Investments. More...

Noël Amenc, Samuel Sender As part of the CACEIS research chair on non-financial risks in investment funds, EDHEC surveyed UCITS and alternative asset managers, their service providers, external observers, and investors for their views of structuring hedge fund strategies as UCITS. The 437 respondents report assets under management (AUM) of more than €13 trillion. Investment fund managers account for roughly €7 trillion of these assets. In general, the survey suggests that institutional investors bound by quantitative restrictions will ask fund managers and distributors to repackage hedge fund strategies as UCITS. For their part, managers of alternative funds are concerned by the uncertainties surrounding the directive on alternative investment fund managers (AIFMs) and may consider packaging their strategies as UCITS. Most respondents, however, fear that structuring hedge fund strategies as UCITS will distort strategies and diminish returns. More...

Abraham Lioui, Patrice Poncet This paper develops a capital asset pricing model based on the production side of a monetary economy. Relying on a general version of the standard Real Business Cycle model with cash and credit goods, we find that the factors determining the mean excess returns on financial assets are i) real capital growth, ii) the nominal interest rate and iii) the capital-to-wealth ratio. Our model is parsimonious in that the results rely neither on any particular specification of the production function nor on capital adjustment costs. Empirical evidence gives strong support to the presence of the elicited factors in the cross section of excess returns on portfolios sorted i) by firm characteristics and ii) by industry. More...

Noël Amenc, Felix Goltz, Adina Grigoriu This paper examines the ways dynamic asset allocation techniques can be used to manage portfolios of exchange-traded funds (ETFs). First, dynamic allocation to stock and bond ETFs and traditional static diversification are compared. Second, tactical allocation to stock and bond ETFs and risk-controlled allocation—with both forms of allocation informed by the same return forecasts—are compared. The paper shows that dynamic asset allocation techniques that can be used with frequently traded and broadly diversified instruments such as ETFs make it possible better to address investor concerns over drawdown and intra-horizon risk, whether or not the manager wishes to make return predictions.

Hilary Till Because many facets of the global oil markets have not been sufficiently transparent, it is unclear how much of the oil-price rally that peaked in July 2008 can be put down to speculation. This uncertainty has led to concerns that there was actually excessive speculation in the oil derivatives markets. In an effort to make the oil markets more transparent, the U.S. Commodity Futures Trading Commission has recently launched the “Disaggregated Commitments of Traders” report. This report includes three years of enhanced market-participant data for twenty-two commodity futures contracts. This report makes it possible to examine whether, over the last three years, speculative position-taking in the exchange-traded oil derivatives markets has been excessive relative to commercial hedging needs.

Octave Jokung In this paper we analyze the conditions under which the presence of a multiplicative background risk induces a more “prudent” behavior. We show that the results from Kimball (1990) concerning the convexity of the marginal utility are no longer sufficient with multiplicative risk. An agent is multiplicative risk prudent when the coefficient of relative prudence is greater than two. We introduce the concept of quintessence in order to guarantee the decrease of relative temperance. Both decreasing relative prudence and decreasing relative temperance are sufficient to guarantee more “prudent” behavior with a multiplicative risk-prudent agent. More...

Christophette Blanchet-Scalliet, Nicole El Karoui, Monique Jeanblanc, Lionel Martellini Many investors do not know with certainty when their portfolio will be liquidated. Should their portfolio selection be influenced by the uncertainty of exit time? In order to answer this question, we consider a suitable extension of the familiar optimal investment problem of Merton (1971), where we allow the conditional distribution function of an agent’s time horizon to be stochastic and correlated to returns on risky securities. In contrast to existing literature, which has focused on an independent time horizon, we show that the portfolio decision is affected.

It views the optimal asset allocation problem of a sovereign wealth fund as the decision-making problem of an investor with non-tradable endowed wealth (oil reserves). Optimal portfolios combine speculative demand (optimal growth) as well as hedging demand (hedging resource fluctuation risk) and the level of risk taking should depend both on the fraction of financial wealth to resource wealth and on the oil shock hedging properties of the investments.

Philippe Foulquier Since the turn of the millennium, a profound shift in the management of insurance companies has been underway. The main catalysts of this shift are the growing complexity of risks, the sophistication of the means of measuring them, and the demands made by investors for greater transparency and for higher-quality management. In this environment, prudential (Solvency II) and accounting (IFRS) requirements must also adapt to create new frameworks offering a better view of the risks borne by companies. All insurers, regardless of their characteristics (public companies, mutual insurers, provident societies) will be subject to the new prudential rules and will thus have to make heavy investments in the data collection, risk measurement, and simulations required by the supervisor. This study shows how, by having these investments respond to objectives more inherent to the company, these Solvency II constraints can be capitalised on. More...

Private Wealth Management
Noël Amenc, Lionel Martellini, Vincent Milhau, Volker Ziemann While the private banking industry is in general relatively well equipped on the tax planning side, with tools that can allow private bankers to analyse the situation of high net worth individuals operating offshore or in multiple tax jurisdictions, the software packages used on the financial simulation side often suffer from significant limitations and cannot satisfy the needs of a sophisticated clientele. In fact, most financial software packages used by private bankers to generate asset allocation recommendations rely on single-period mean-variance asset portfolio optimisation, a tactic that, for at least two reasons, cannot lead to proper strategic allocation. This study provides a formal framework suggesting that asset-liability management can ensure that private wealth managers are able to offer their clients investment programmes and asset allocation advice that truly meet their needs.

fierce debate in most developed countries between advocates of a tighter regulation designed to provide explicit incentives for pension funds to increase their focus on risk management, and those arguing that imposing short-term funding constraints and solvency requirements on such long-term investors would only increase the cost of pension financing. We analyse this question in the context of a formal continuous-time dynamic asset allocation model for an investor facing liability commitments subject to inflation and interest rate risks. In an empirical exercise, we find that the presence of short-term funding ratio constraints indeed involves a positive welfare cost, but that cost is not found to be prohibitive for reasonable parameter values.

Felix Goltz The EDHEC European Investment Practices Survey 2008 (EDHEC 2008) sheds light on current practices in the industry and compares these practices with the recent state of the art as described in the investment literature.
The results of the survey show that the industry does not fully exploit a number of proven portfolio optimisation techniques that research has made readily available, such as management of extreme risks, improved covariance
estimation or Bayesian and resampling techniques.
We called for reactions to these results; the objective was to get feedback from

Noël Amenc, Lionel Martellini, Volker Ziemann This paper presents an empirical analysis
of the benefits of alternative forms of
investment strategies from an asset-liability
management perspective. Using a vector error correction model (VECM)
that explicitly distinguishes between short-term
and long-term dynamics in the joint
distribution of asset returns and inflation,
we identify the presence of long-term
cointegration relationships between the
return on typical pension fund liabilities
and the return of various traditional and
alternative asset classes. A revisited version of this paper was published in the Summer 2009 issue of The Journal of Portfolio Management. More...

Véronique Le Sourd This paper analyses twelve years of data on EDHEC Alternative Indexes for different hedge fund strategies to provide some perspective on their performance. The extraordinary events of 2008 were not without an impact on hedge fund returns. Funds of hedge funds lost 17% in 2008, posting their worst annual returns since we began keeping records in 1997. Hedge fund investments lost value across the board. Except for CTAs and Short Sellers, all strategies posted their worst losses in 2008. Even after the impact of a calamitous year, half the strategies still post cumulative returns above 100% for the past ten years, that is, a compound annual return above 7%. More...

Greg N. Gregoriou, François-Serge Lhabitant For more than seventeen years, Bernard Madoff operated what was viewed as one of the most successful investment strategies in the world. This strategy ultimately collapsed in December 2008 in what financial experts are calling one of the most detrimental Ponzi schemes in history. Many large and otherwise sophisticated bankers, hedge funds, and funds of funds have been hit by his alleged fraud. In this paper, we review some of the red flags that any operational due diligence and quantitative analysis should have identified as a concern before investing. We highlight some of the salient operational
features common to best-of-breed hedge funds, features that were clearly missing from Madoff’s operations. A revisited version of this paper was published in the Summer 2009 issue of The Journal of Wealth Management. More...

Felix Goltz, David Schröder Like any investors, investors in hedge funds are naturally interested in knowing how hedge fund managers allocate their initial investment, and whether this allocation yields positive returns or not. It is not only information on past investment returns that is of particular interest; prospects for future gains or losses are relevant to investors as well. Yet, unlike mutual funds, hedge funds are reluctant to provide detailed information on their investment portfolios. Since many hedge funds use highly speculative investment strategies, fund managers fear that a thorough disclosure of their portfolio holdings would significantly decrease their chances of winning their bets, and thereby reduce investors' returns. But incomplete disclosure can have some undesirable side effects. A revisited version of this research was published in the Spring 2010 issue of the Journal of Alternative Investments.

Regulation
Noël Amenc, Samuel Sender The financial crisis has put great pressure on banks and led to a number of emergency measures intended to restore confidence in the banking system: tentative changes to accounting standards, recapitalisation of the banking industry, and higher capital requirements. Each measure targets a specific concern that has arisen during the crisis. Governments and regulators, however, have yet to deal with one of the essential causes of systemic risk: the inflexibility of prudential regulation for banking. As it happens, a single minor change would make it possible to restore much of the confidence in the
banking sector without requiring any capital injections in the short term: acknowledging that banking capital ratios fall during downturns would have made most of the injections of public funds unnecessary. Making this change today would give governments far more room to support the real economy. More...

The call for reaction received more than 800 responses and represents the first international survey on the relevance of the reforms carried out by the IASB under pressure from the European Commission. The results of this study correspond to EDHEC’s initial arguments. Fewer than a quarter of the respondents believe that these amendments are necessary and well suited to resolving the problems of bank solvency.

Private Wealth Management
With the great economic growth of the past decade, private wealth management
has become a very profitable business for banks worldwide. As a result, more

These industry changes have led to renewed attempts to improve client relationships and to develop tools and methods to enhance advisor effectiveness. Catering to the client’s specific needs is thus a central concern of private wealth managers. To take the client objectives into account, investments are frequently adapted to the client’s risk aversion, tax situation, and investment horizon.

In US dollar terms, crude oil prices increased 525% from the end of 2001 through July 31st, 2008. Was this rally yet another speculative bubble? Specifically, was the oil-price rally based on speculative excess rather than fundamental supply-and-demand factors? In a new position paper, “The Oil Markets: Let the Data Speak for Itself”, we argue that when the oil supply-and-demand balance becomes sufficiently tight and that when effective OPEC spare capacity becomes sufficiently low that it is logical to see very high prices to ration demand and/or encourage additional supply. That is the job and message of price, even if this message is unpopular. More...

David E.

If a manager of a fund of hedge funds (FoF) finds that the exposure of the FoF to a certain systematic exposure or the risk level broadly has become excessive, then the FoF manager may want to hedge. The purpose of this article is to outline the major issues involved with overlay hedging in a fund of funds portfolio and to provide relevant solutions to these issues. These include the determination of whether to hedge, exposure estimation, hedging single exposures with futures, options, and other instruments, and hedging exposures broadly using a multi-factor approach.

Furthermore, an analysis of both the style exposures and the sector exposures of characteristics-based indices reveals a significant value tilt. When properly adjusting for this tilt, these indices do not show any abnormal performance. A revisited version of this paper was published in the February 2009 issue of European Financial Management.

The EDHEC European ETF Survey 2008 is part of the EDHEC Risk and Asset
Management Research Centre’s Indices and Benchmarking research programme. This programme has led to extensive research on indices and benchmarks in both the hedge fund universe and the more traditional investment classes. In 2006, EDHEC published a study of the quality
of major stock market indices. Following up on this study, EDHEC is carrying out
work that assesses the advantages and disadvantages of various new forms of
equity indices.
In view of the growth and development of ETFs in Europe, and in view of their
growing popularity as investment media for both index management and
the construction of benchmarks, it is only natural that EDHEC should devote
significant resources to research into ETFs. In 2006, with the support of iShares, we published the first EDHEC European ETF survey. The present survey, an update and extension of the 2006 survey, sheds light on recent developments and trends in ETF investing.

As part of its ongoing policy of monitoring asset management practices and comparing them with the results of academic research, the EDHEC Risk and Asset Management Research Centre undertook an in-depth survey of the risk management, portfolio construction, strategic allocation, and performance measurement practices of European asset managers and investors.
The EDHEC European Investment Practices Survey is built on a sample of 229 institutional investors and asset managers who, with respect both to the nationality of survey respondents and to the amount of assets under management, are largely representative of the European asset management industry. In all, respondents to the survey have more than €10 trillion of assets under management and include the major European firms in the industry (nearly fifty respondents manage more than €100 billion each).

Noël Amenc, Felix Goltz, Véronique Le Sourd This paper analyses a set of characteristics-based indices that were recently launched on the US market and that, it has been argued, outperform standard market cap-weighted indices over particular backtest samples by a considerable margin. It analyses the performance of an exhaustive list of these indices and shows that i) the outperformance over value-weighted indices may be negative over long time periods, and ii) that there is no significant outperformance over simple equal-weighted indices. Furthermore, an analysis of both the style and sector exposures of characteristics-based indices reveals a significant value tilt. When properly adjusting for this tilt, these indices do not show any abnormal
performance. Therefore, the paper argues that the main value these indices add may be to provide investors with a liquid, systematic, and relatively cheap alternative to other value-tilted strategies. However, if one recognises the possibility to implement tilts of exposures to sector or style factors, constructing
factor portfolios that beat the characteristics-based indices in the sense of mean-variance efficiency is straightforward. More...

James Chong, Joëlle Miffre The article studies the temporal variations in the conditional return correlations between commodity futures and traditional asset classes (global stock and fixed-income indices). It reveals that the conditional correlations between commodity futures and S&P500 returns fell over time, a sign that commodity futures have become better tools for strategic asset allocation. The correlations with equity returns also fell in periods of above average volatility in equity markets. We see this as welcome news to long institutional investors as they need the benefits of diversification most in periods of high volatility in equity markets. Similarly, falls in return correlations between commodity futures and Treasury-bills go hand in hand with rises in short-term interest volatility, suggesting that adding commodity futures to Treasury-bill portfolios reduces risk further in volatile interest rate environments.

This model is applied to international equity and bond markets to investigate their dependence structure.

The results obtained using Monte Carlo analysis show that investors should allocate between 45% and 63% of their
portfolio to such portfolio insurance strategies. Moreover, the inclusion of portfolio insurance strategies leads to important utility gains. The results are robust with respect to the choice of the objective, the presence of realistic levels of market friction, heterogeneous expectations on volatility, and various parametric assumptions.

Aron Balas, Rafael La Porta, Florencio Lopez-de-Silanes, Andrei Shleifer Djankov et al. (2003a) propose and measure for 109 countries in the year 2000 an index of formalism of legal procedure for two simple disputes: eviction of a non-paying tenant and collection of a bounced check. For a sub-sample of 40 countries, that authors compute this index every year starting in 1950, which allows them to study the evolution of legal rules. They find that between 1950 and 2000 the formalism of legal procedure did not converge, and possibly diverged, between common law and French civil law countries. At least in this specific area of law, the results are inconsistent with the hypothesis that national legal systems are converging, and support the view that legal origins exert long-lasting influence on legal rules.

Lionel Martellini Following recent research on the relevance of idiosyncratic risk in asset pricing models, this paper proposes to use total volatility as a model-free estimate of a stock's excess expected return, and analyze the implications in terms of the design of improved equity benchmarks. It finds that maximum Sharpe ratio portfolios consistent with such expected return proxies, and built upon improved estimates of the correlation parameters, significantly outperform market cap weighted schemes on a risk-adjusted basis. This analysis, which rehabilitates the role of the tangency portfolio from modern portfolio theory, suggests that better equity benchmarks can be designed, provided that a sophisticated portfolio optimization procedure is used that relies on robust estimates of moments and co-moments of stock return distributions. This paper has important potential implications for the ongoing debate on appropriate weighting schemes for equity indices.

Real Estate
The EDHEC Risk and Asset Management Research Centre has released a new survey that is drawn from its research programme in asset allocation and alternative diversification. This programme has led to extensive research on the benefits, risks, and integration methods of alternative classes and instruments in asset allocation.
Real estate, probably the most traditional of alternative classes, is enjoying renewed favour as institutional investors search for diversification benefits and competitive yields. Institutional demand for real estate exposure has brought about improvements in market transparency and the development of new indirect and synthetic investment tools. With target allocations to real estate
increasing, research into real estate as an asset class must enable industry participants to refine traditional approaches and to consider real estate within the bounds of asset management and asset-liability management. It is in this way that research can help real estate take its place in multistyle, multi-class portfolios, contribute to the design of integration methods that optimise its risk/return trade-off, and, finally, enable the class to deliver on its full potential.
The EDHEC European Real Estate Investment and Risk Management Survey, the first phase of this research, takes stock of developments in the real estate investment market, reviews academic evidence on allocation to and management of real estate, and analyses the results of a large-scale, pan-European survey of institutional practices.

A recent publication by the EDHEC Risk and Asset Management Research Centre has drawn conclusions that highlight the shortcomings of well known capitalisation- or price-weighted stock market indices and argues that the choice of benchmark for asset allocation or performance measurement is a task requiring particular care.
In a call for reactions to this publication, EDHEC finds that the answers of the more than eighty respondents (asset management firms, pension funds, insurance companies, private banks, etc.) tend to reinforce the conclusions drawn by the original publication.
Although it would at first appear that the majority of respondents are not, in general, dissatisfied with the indices they use as benchmarks (18.82% of respondents express degrees of dissatisfaction), further examination soon reveals that the shortcomings of these indices, such as inefficiency, lack of stability, and susceptibility to price bubbles, are widely recognised by the

European leaders, eager for an explanation absolving them of responsibility, have once again laid blame on the seemingly detrimental role played by hedge funds in this summer’s crisis. This crisis is the result of a sudden fall in asset
prices, combined with increased aversion to risk on the part of investors. To suggest that hedge funds are to blame for this crisis is simplistic but tempting, as their speculative, unregulated, and opaque nature make them easy targets - all the while, more delicate market and regulatory issues are avoided. So, as a counterpoint to these accusations that often come from France, it seemed necessary to us to provide a French perspective on the lessons to be learned with respect to financial regulation in France.

This brief article suggests three approaches for how to benefit from structural opportunities in the commodity markets, drawing from the recently published book, “Intelligent Commodity Investing.” The author notes how over long time horizons, the term structure of a commodity futures curve becomes the dominant driver of return for individual futures contracts. For shorter time horizon opportunities, the author discusses mean-reverting commodity spread trades that have approximately seasonal frequencies. More...

Within the equity risk sub-module of the third Quantitative Impact Study (QIS3) undertaken by the Committee of European Insurance and Occupational Pension Supervisors (CEIOPS), a preamble to the Solvency II supervisory standard, all alternative investments are subject to a capital charge of 45%, nearly 50% higher than the 32% applied to regular equity exposures. In this article, we briefly go over the calculations required for equity risk, and then include a reminder of why hedge funds on average are certainly not the riskiest bet an investor can make.

Order Execution
Rudy De Winne, Catherine D’Hondt This paper investigates why traders hide their orders and how other traders respond to hidden depth. Using a logit model, the authors provide empirical findings suggesting that traders use hidden orders to manage both exposure risk and picking off risk. Using probit models, they show that hidden depth increases order aggressiveness. The authors' interpretation of this empirical evidence is threefold. First, hidden depth detection is possible and frequent. Second, when traders detect hidden volume at the best opposite quote, they strategically adjust their order submission to seize the opportunity for depth improvement. A revisited version of this paper was published in the September 2007 issue of Review of Finance (formerly European Finance Review). More...

Xiafei Li, Chris Brooks, Joëlle Miffre Numerous studies have documented the failure of the static and conditional capital asset pricing models to explain the differences in returns between value and growth stocks. This paper examines the post-1963 value premium by employing a model that captures the time-varying total risk of the value-minus-growth portfolios. The results show that the conditional variance model incorporating time-varying idiosyncratic risk can fully capture the post-1963 value premium. The conclusion is robust to the criterion used to sort stocks into value and growth portfolios, to the inclusion of the size premium into the conditional asset pricing model, and to the country under review (US and UK). This paper therefore adds to the debate on the possible role of idiosyncratic risk in explaining equity returns. A revisited version of this paper was published in the November/December 2009 issue of the Journal of Business Finance and Accounting. More...

David Kuenzi Volatility is an alternative beta—a risk premium captured by hedge fund managers and investment bank proprietary traders—that is today moving closer to the mainstream and should be thought of as a veritable asset class. For many investors, it is difficult to derive intuition as to why volatility should deserve an ongoing allocation within a larger portfolio. If volatility is an asset class, then to what accepted asset class can it be compared? More...

Harry M. Kat, Joëlle Miffre This paper highlights the importance of non-normality risks and tactical asset allocation in assessing hedge fund performance. As such, it underlines the inaccuracies of previous papers on hedge fund performance that ignored higher moments in the distribution of hedge fund returns and assumed constant asset allocation. Correcting for these shortcomings, the authors find that failure to account for non-normality risks and tactical asset allocation on average leads to an overstatement of performance by 1.54% and to incorrect statistical inference on the performance of 1 out of 4 funds. On average, non-normality risks and conditional asset allocation explain 23.1% of the abnormal performance of hedge funds as commonly perceived. A revisited version of this paper was published in the Spring 2008 issue of the Journal of Alternative Investments. More...

In this study, EDHEC-Risk Institute, while recognising that the directive allows the conditions in which investment companies can operate on the regulated markets or over-the-counter to be harmonised, warns of the eventual adverse effects relating to the obligation of transparency for systematic "internalisers" and the obligation of "best execution". The authors find, in the case of the obligation imposed on systematic “internalisers” to maintain a public spread of prices, that it is prejudicial for this restriction to be removed for the least liquid securities. This provision will lead, in a certain number of cases, (small-caps on markets that are centrally organised at present), to a deterioration in the pre-trade transparency that is currently provided to investors.

Wealth Management
Working from the observation that the contribution of asset-liability management techniques developed for institutional investors is not yet familiar within private banking, a new study from the EDHEC Risk and Asset Management Research Centre, entitled “Asset-Liability Management Decisions in Private Banking” shows the expected benefits of a transposition of that kind. According to the authors of the study, Noël Amenc, Lionel Martellini and Volker Ziemann, asset-liability management represents a genuine means of adding value to private banking that has not been sufficiently explored to date. Within the framework of private financial management offerings, personal wealth managers tend to confine their clients to mandates that are only differentiated through their level of volatility, without the client’s personal wealth constraints and objectives being genuinely taken into account in order to determine the overall strategic asset allocation. In that sense, private wealth management is not sufficiently different from the management of a diversified or profiled mutual fund. More...

Performance
Walter Briec, Kristiaan Kersten, Octave Jokung This paper proposes a nonparametric efficiency measurement approach for the static portfolio selection problem in mean-variance-skewness space. A shortage function is defined that looks for possible increases in return and skewness and decreases in variance. Global optimality is guaranteed for the resulting optimal portfolios. We also establish a link to a proper indirect mean-variance-skewness utility function. For computational reasons, the optimal portfolios
resulting from this dual approach are only locally optimal. This framework makes it possible to differentiate between portfolio efficiency and allocative efficiency, and a convexity efficiency component related to the difference between the primal, non-convex approach and the dual, convex approach. Furthermore, in principle, information can be retrieved about the revealed risk
aversion and prudence of investors. An empirical section on a small sample of assets serves as an illustration. A revisited version of this paper was published in the January 2007 issue of Management Science. More...

Ana-Maria Fuertes, Joëlle Miffre and Wooi-Hou Tan This paper examines the role of non-normality risks in explaining the momentum puzzle of equity returns. It shows that momentum returns are not normally distributed. About 70 basis points of the annual momentum profits can be attributed to systematic skewness risk. This finding is pervasive across nine strategies and is reinforced when time dependencies in abnormal returns and risks are explicitly modeled. The analysis also reveals that the market and skewness risks of momentum portfolios evolve over the business cycle in a manner that is consistent with market timing and risk aversion.

Daniel Giamouridis and Ioanna Ntoula This paper compares a number of different approaches for determining the Value at Risk (VaR) and Expected Shortfall (ES) of hedge fund investment strategies. The authors compute VaR and ES through completely model-free methods, as well as through mean/variance and distribution model-based methods. Among the models considered certain specifications can technically address autocorrelation, asymmetry, fat tails, and time-varying variances which are typical characteristics of hedge fund returns. They find that conditional mean/variance models coupled with appropriate distributional assumptions improve their ability to predict VaR, 1% VaR in particular. They also find that the goodness of ES prediction models is primarily influenced by the distribution model rather than the mean/variance specification.

Exchange-Traded Funds
In a new survey, The EDHEC European ETF Survey 2006, the EDHEC Risk and Asset Management Research Centre has carried out an in-depth study on the use of ETFs (Exchange-Traded Funds) by European investors. The results of the survey show that following rapid growth, ETFs are being widely used by European institutional investors, private bankers and asset managers. The increasing popularity of ETFs is reflected in the responses of survey participants. More than half of the respondents are current or planned users of ETFs in equity investments (61%), and this is the case for more than a quarter of respondents (26%) for bond investments.
More remarkably, among those that use Equity ETFs, 92% were satisfied, which indicates an extremely high level of satisfaction. With 45% of responses, the most distinct reason for satisfaction was the reliability of the tracking error. 23% were satisfied with the good performance of ETFs, while 21% were pleased with the level of liquidity, and only 4% cited the reduced expenses of ETFs. Interestingly, half of the respondents who were not satisfied with Equity ETFs pointed to the poor level of liquidity of ETFs. More...

A new study jointly produced by the EDHEC Risk and Asset Management Research Centre and the EDHEC Financial Analysis and Accounting Research Centre entitled ‘The Impact of IFRS and Solvency II on Asset-Liability Management and Asset Management in Insurance Companies’ reveals the contradictions inherent in the current Solvency II and IFRS provisions for insurance companies. The report shows notably that the numerous provisions proposed by the IFRS are at odds with the good risk management practices put forward by Solvency II. While IFRS and Solvency II should lead to a genuine evolution in the management of insurance companies, by empowering them with respect to their risks (identification, measurement and management), one is forced to observe today that the standards implemented often oppose their initial objectives: the adoption of modern asset management and ALM techniques with a view to reducing the exposure to risks is considerably penalised by the IFRS treatment by leading to additional purely accounting volatility, without any connection to the economic reality.

Transaction Cost Analysis
Jean-René Giraud, Catherine d’Hondt MiFID is the second step in the harmonization of the European capital markets industry and intends to adapt the first Investment Services Directive (ISD 1 issued in 1993) to the realities of the current market structures. After having clarified the nature of the new regulation, this paper first describes the role of Transaction Cost Analysis in the fulfilment of the best execution obligation as well as the limits of existing frameworks. Then, the paper presents a new methodology that makes it possible to measure the quality of execution as part of peer group review and identify whether the broker, trader or algorithm has implemented the execution too aggressively or too slowly. This approach relies on a couple of indicators allowing an easy comparison of a large universe of trades and providing insightful information not only about the final performance (EBEX absolute indicator) but also about the possible justification of the performance (EBEX direction). In order to illustrate both the framework and the level of interpretation made possible, the results of a preliminary study conducted on 2737 orders on Euronext blue chips over a 4-month sample period are reported.

We disagree with this conclusion, which is based on mere speculation. We outline the fallacies in the reasoning of the FSR article and makes some propositions on how to assess the welfare impacts of hedge funds. In particular, we argue that it would be worthwhile for financial regulators to work towards obtaining data on hedge fund leverage and counterparty credit risk. Such data would allow a reliable assessment of the question of systemic risk. In addition, we argue that besides evaluating potential systemic risk, it should be recognised that hedge funds play an important role as “providers of liquidity and diversification.” More...

The results show that the non-linear character of the returns on protective option strategies offers appealing risk reduction properties in the pure asset management context. Consequently, such strategies should optimally receive a significant allocation, especially when investors are concerned with minimising extreme risks.

Without quality benchmarks, it is not possible to differentiate between returns due to the investment style of the manager and returns due to the talent of the manager, which in turn makes it difficult to measure relative returns. This paper examines the issue of hedge fund strategy benchmarks in the light of improvements in hedge fund index construction methodologies and management principles, and with the launch of new series of investable hedge fund indices.

Because ETFs can be sold short even on a downtick, global strategies that diversify risk across country-specific ETFs generate efficiency gains that cannot be achieved by simply investing in a global index open- or closed-end fund. Besides, the benefits of international diversification can be achieved with country-specific ETFs at low cost, with low tracking error and in a tax-efficient way. For all these reasons, country-specific ETFs may be considered serious competitors to traditional country open and closed-end funds.

This inadequacy came to light in a study published by EDHEC in 2003, a study that showed that a very large majority of European hedge fund managers were satisfied with a reporting method designed for investment in traditional asset classes. This method proposes a mean variance-structure that is inappropriate for the risk and return profiles of alternative investment and does not inform investors of extreme risk and risk factors affecting the different returns of the hedge fund strategies in which the funds of funds are invested.

The share of return variance explained by backwardation rises from 24% at a one-year horizon to 64% using five-year time periods.

Lionel Martellini. In this paper, the author considers an intertemporal portfolio problem in the presence of liability constraints. Using the value of the liability portfolio as a natural numeraire, he finds that the solution to this problem involves a three fund separation theorem that provides formal justification to some recent so-called liability-driven investment solutions offered by several investment banks and asset management firms, which are based on investment in two underlying building blocks (in addition to the risk-free asset), the standard optimal growth portfolio and a liability hedging portfolio.

The study generated responses from 151 European institutional investors representing, at 30/09/2005, a total volume of over one trillion euros of assets under management. The survey shows that 51% of European institutional investors are already exposed to hedge fund strategies. These represent, on average, 7% of their global assets. More...

Daniel Capocci Hedge funds have an absolute return performance objective stated independently of the global market conditions. Nevertheless they have been compared to classical bond and equity indices by academics since the late 90s. Independently of their absolute or relative performance it is of particular importance to determine if some hedge funds consistently outperform their peers. This is exactly the objective of this study: Do some hedge funds consistently and significantly outperform others? Do some individual funds or some strategies continuously create alpha in comparison to others? More...

Lionel Martellini, Mathieu Vaissié and Volker Ziemann. One of the by-products of the bull market of the 90’s has been the consolidation of hedge funds as an important segment of financial markets. It was recently announced that the value of the hedge fund industry worldwide had passed the $1 trillion mark for the first time, with approximately 7,000 hedge funds in the world, around 1,000 of which were launched in 2003. One of the key reasons behind the success of hedge funds in institutional money management is that such alternative investment strategies seem to provide diversification benefits with respect to other existing investment possibilities. In an attempt to fully capitalize on such beta benefits in a top-down approach, investors or (funds of hedge funds) managers must be able to rely on robust techniques for optimization of portfolios including hedge funds.

Operational Risk
Jean-René Giraud Operational risk is by far the most complex and intriguing issue investors are dealing with when allocating capital to hedge funds. Due to sophisticated trading strategies, potentially high levels of portfolio turnover, investment in illiquid or difficult to price instruments and a moderately regulated environment, hedge funds tend to exhibit high levels of extreme risks related to non-financial events (fraud and misappropriation, misrepresentation, model risk, infrastructure risk, etc.).

Asset-Liability Management
Noël Amenc, Lionel Martellini, Felix Goltz. As a consequence of entering a more mature stage, the hedge fund industry has extended its investor base to institutional investors, who are now faced with a large number of product offerings including not only single hedge funds, but also funds of funds and, more recently, investable indexes. Although the existing literature seems to concur on the interest of hedge funds as valuable investment alternatives, there still remain a large a large number of institutional investors who wonder whether they should invest in hedge funds, and more importantly, how they should do it. In order to address these questions, this paper looks at the risk factors in hedge fund strategies and attempts to assess the diversification benefits investors can expect from allocating part of their wealth to hedge funds.

Strong assumptions are often made to simplify the risk estimation process and there has to be a trade-off between ease of estimate and accuracy. In this paper, “Is there a gain to explicitly modelling extremes? A risk measurement analysis”, Jean-Christophe Meyfredi of the Edhec Risk and Asset Management Research Centre develops a copula-based approach in order to estimate the Value-at-Risk of portfolios containing financial assets.

This seems to be surprising given that an increasingly thorough range of structured products has been developed over the past few years, which allows investors to tailor the risk-return profile of their portfolio in a more efficient way than simple linear exposure to traditional asset classes. The salient characteristic of structured products is the repackaging of strategies that involve long and short positions in derivatives and the underlying or a risk-free asset into an investment vehicle that is easily accessible by investors.

Asset Allocation
Lionel Martellini, Branko Uroševic In this paper, we generalize Markowitz analysis to the situations involving an uncertain exit time. Our approach preserves the form of the original problem in that an investor minimizes portfolio variance for a given level of the expected return. However, inputs are now given by the generalized expressions for mean and variance-covariance matrix involving moments of the random exit time in addition to the conditional moments of asset returns. While efficient frontiers in the generalized and the standard Markowitz case may coincide under certain conditions, we demonstrate, by means of an example, that in general that is not true. In particular, portfolios efficient in the standard Markowitz sense can be inefficient in the generalized sense and vice versa. As a result, an investor facing an uncertain time-horizon and investing as if her time of exit is certain would in general make sub-optimal portfolio allocation decisions. Numerical simulations show that a significant efficiency loss can be induced by an improper use of standard mean-variance analysis when time-horizon is uncertain.

Walter Géhin, Mathieu Vaissié. Two studies, by Watson Wyatt and UBS (both from March 2005), give a pessimistic view of the hedge fund industry’s capacity to generate long-term returns, due to its increasing size. Unfortunately, these studies focus almost exclusively on alpha. In the present paper, we show the importance of considering not only the exposure to the market (the traditional beta), but also the other exposures (the alternative betas) to cover all the sources of hedge fund returns. To do so, we examine the real extent to which the variability and level of hedge fund returns are affected by (static) betas, dynamic betas (i.e. factor timing), and pure alpha (i.e. security selection). A revisited version of this study was published in the Summer 2006 issue of The Journal of Alternative Investments.

Frank J. Fabozzi, Lionel Martellini, Philippe Priaulet This paper presents evidence of predictability in the time-varying shape of the U.S. term structure of interest rates using a robust recursive modelling approach based on a Bayesian mixture of multi-factor models. We find that variables such as default spread, equity volatility, short-term and forward rates, among others, can be used to predict changes in the slope of the yield curve, and also, albeit to a lesser extent, changes in the curvature of the yield curve. By using systematic trading strategies based on butterfly swaps, we also find that this evidence of predictability in the shape of the yield curve is economically significant in addition to being statistically significant.

Using active bond portfolio management as an example, they present evidence on the use of derivatives by managers for generating and delivering abnormal performance, and also for packaging such performance in a form that is consistent with the modern core-satellite approach to institutional portfolio management, for which they explore both a standard static version and also a dynamic extension allowing for dissymmetric control of active management risk.

Most of these problems can be avoided by using an adequate compensation theme.

Temporal aspects complicate the problem but give rise to special
opportunities for dynamic investment strategies.Within these models, the portfolio must be re-revised in the face of transaction and market impact costs.

Just like with good and bad cholesterol, there is “good” tracking error, which refers to out-performance of a portfolio with respect to the benchmark, and “bad” tracking error, which refers to underperformance with respect to the benchmark. By severely restricting the amounts invested in active strategies as a result of tight tracking error constraints, investors forgo an opportunity for significant out-performance, especially during market downturns.

Tactical Allocation
N. Amenc, P. Malaise, L. Martellini and D. Sfeir. There is now a consensus in empirical finance that expected asset returns, and also variances and covariances, are, to some extent, predictable. The use of predetermined variables to predict asset returns has produced new insights into asset pricing models, and the literature on optimal portfolio selection has recognized that these insights can be exploited to improve on existing policies based upon unconditional estimates. While the performance of tactical style allocation models is well documented in equity markets, very little evidence is available on the performance of systematic dynamic allocation decisions among various bond indices. This paper investigates the predictability of fixed-income style portfolio returns using a robust recursive modeling approach based on multi-factor models for the return on bond indices.

to remain meaningful even if their numerical parameters are not estimated
with very high accuracy or, alternatively, if small perturbations are applied to
the parameter values. Things can be quite different, however, with models developed for financial

that existing style indexes can provide a somewhat confusing picture of the return on these
factors. More...

L. Martellini, B. Urosevic. Executive compensation packages are often valued in an inconsistent manner: while employee
stock options (ESOs) are typically valued ex-ante, i.e., before uncertainties are resolved, cash
bonuses are valued ex-post, i.e., by discounting the realized cash grants. Such a lack of
consistency can, potentially, distort empirical results. A related, yet mostly overlooked, problem
is that when ex-post valuation is used pay-performance measures can not be well defined.
Consistent use of ex-ante valuation for all components of a compensation package would
simultaneously resolve both of these problems and provide a natural framework for the analysis of agency problems. More...

Noël Amenc, Philippe Malaise, Lionel Martellini and Daphne Sfeir. Even though there is little evidence of predictability in stock specific risk in the absence of private information, most equity market neutral managers still rely on stock picking as the preferred way to generate abnormal returns. In this paper, we document the benefits of a new form of market-neutral portfolio strategy that aims at deliver absolute return over the full business cycle through systematic equity style timing decisions. A revisited version of this paper was published in the Summer 2003 issue of the Journal of Alternative Investments. More...

Business Analysis
Edhec has conducted a major survey into the practices of the leading 400 European asset management firms which generated responses from 60 companies. The survey is the first study conducted in Europe dealing with the application of the results of academic research within investment management companies. The survey results reveal that in spite of their extensive knowledge of the concepts involved in research into portfolio management and the progress made, the major European asset managers were either not implementing them or not adopting them rapidly as part of their investment management process.

In this paper, we propose an integrated framework for assessing the risk-adjusted performance of
mutual fund managers. The methodology is designed so as to be consistent not only with modern
portfolio theory but also with constraints imposed by practical implementation in a context where
the presence of a variety of investment styles needs to be accounted for. A revisited version of this paper was published in the Summer 2003 issue of the Journal of Performance Measurement.

Different hedge fund indexes available on the market are constructed from different data, according to diverse selection criteria and methods of construction, and they evolve at differing paces. As a result of this heterogeneity, investors cannot rely on competing hedge fund indexes to obtain a “true and fair” view of hedge fund performance. Investors are therefore at a loss when selecting benchmarks. As a response to the needs of investors, the Edhec Risk and Asset Management Research Center proposes an original solution by constructing an “index of indexes.” The aim of the methodology used to construct this “index of indexes” is to construct a benchmark with degrees of representativity and stability that are significantly higher than those of the indexes available on the market.

Asset Allocation
Jaksa Cvitanic, Ali Lazrak, Lionel Martellini and Fernando Zapatero.
What percentage of their portfolio should investors allocate to hedge funds? The
only available answers to the above question are set in a static mean-variance framework,
with no explicit accounting for uncertainty on the active manager’s ability to generate abnormal return, and usually generate unreasonably high allocations to hedge funds.
In this paper, we apply the model introduced in Cvitanic, Lazrak, Martellini and Zapatero
(2002) for optimal investment strategies in the presence of uncertain abnormal returns
to a database of hedge funds. Wefind that the presence of model risk significantly
decreases an investor’s optimal allocation to hedge funds. Another finding of this
paper is that low beta hedge funds may serve as natural substitutes for a significant
portion of an investor risk-free asset holdings. A revisited version of this paper was published in the February 2003 issue of Quantitative Finance. More...

The present paper conducts an empirical study by examining the Market Model and the three versions of the 4-State Model (translated, rotated and un-rotated) in a mean-beta framework. Using daily returns from the CAC 40 Index’s assets, we find that the explanatory power of the 4-State Model is greater than the one of the Market Model and this effect is improved by rotation. A reduction in the non-systematic risk is also observed when switching from Market Model to 4-State Models. Surprisingly, the betas are more stable when using any version of the 4-State Model.

Two competing approaches are used in practice to build portfolios: bottom-up and topdown.
The bottom-up approach is the older and the more traditional, and focuses on
individual stock picking. The top-down approach gives more importance to the choice of
different markets as opposed to individual security selection, and, as such emphasizes the
importance of asset allocation. More...

While there has been a significant amount of research on the predictability of traditional
asset classes, very little is known about the predictability of returns emanating from alternative vehicles such as hedge funds. This paper attempts to fill this gap by documenting evidence of predictability in hedge fund returns. A revisited version of this paper was published in the September/October 2003 issue of the Financial Analysts Journal. More...

The fact that hedge funds have started to gain widespread acceptance while remaining a somewhat mysterious asset class enhances the need for better measurement and benchmarking of their performance. One serious problem is that existing hedge fund indices provide a somewhat confusing picture of the investment universe. In this paper, we first present detailed evidence of strong heterogeneity in the information conveyed by competing indices. We also attempt to provide remedies to the problem and suggest various methodologies designed to help build a “pure style index”, or “index of the indices” for a given style. More...

The growth of alternative investment has been considerable in recent years.

Laurent Favre, José-Antonio Galeano. Based on the normal Value-at-Risk, we develop a new Value-at-Risk method called Modified Value-at-Risk. This Modified Value-at-Risk has the property to adjust the risk, measuring with
the volatility only, with the skewness and the kurtosis of the distribution of returns. The Modified
Value-at-Risk allows to measure first the risk of portfolio with assets non normally distributed
like hedge funds or technology stocks and to compute optimal portfolio by minimizing the
Modified Value-at-Risk at a given confidence level. A revisited version of this paper was published in the Autumn 2002 issue of the Journal of Alternative Investments. More...

Fund performance measurement is an important issue both for professionals, for whom it is the
justification of their remuneration, and for researchers, for whom the right evaluation of returns and risks constitutes the very core of modern portfolio theory.
This twofold academic and professional issue underlies extensive research and numerous methods
for evaluating the performance of funds.
Indeed, the diversity of the resulting models and methods has consequences on fund performance rankings and the evaluation of fund performance.
Identifying the best managers actually presupposes taking two areas into account - the risk and the management style. The modelling of those two areas is subject to substantial debate and theoretical and statistical options. More...

Laurent Favre, Andreas Signer. In this paper, the use mean-variance approach for the determination of the benefits of allocations
to hedge funds is critically evaluated. The advantages of investing in hedge funds are often
explained and demonstrated with reference to a shift in the efficiency frontier of traditional
portfolios. The added value of hedge funds is almost always indicated in a mean-standard
deviation environment and should in our view be reconsidered. The estimated risk exposure can
be quantified by the introduction of Value-at-risk analysis corrected according to higher moments
of distribution. With this new risk measure, we are able to obtain a corrected value. A revisited version of this paper was published in the Summer 2002 issue of the Journal of Alternative Investments. More...

Laurent Favre, José-Antonio Galeano. In this article, we analyze the returns distribution of Hedge Funds strategies, the average returns
obtained over the past ten years and their correlation with a traditional portfolio. The aim is to
identify the characteristics of each Hedge Fund investment strategy in order to be able to
construct an optimal Hedge Fund portfolio for a Swiss pension fund. We will show that the
classical linear correlation and the classical linear regression cannot be applied for Hedge Funds.
Moreover, we will show that only three strategies, Convertible Arbitrage, Market Neutral and
CTA, give diversification during market downturns. The techniques used are non-linear
regressions and local correlations. A revisited version of this paper was published in the Spring 2002 issue of the Journal of Alternative Investments. More...

François-Serge Lhabitant. Under the efficient market hypothesis, overwriting calls or purchasing
insurance should not improve risk-adjusted portfolio returns. A proper analysis
should show that if options are traded at a fair cost, the risk-reward characteristics
of an option position would fall on the efficient market line. In this paper we
show that, due to several limitations of mean-variance analysis, this is not the
case in practice. We quantify and identify the nature of the resulting biases for
performance evaluation, and explain why alternative measures such as semi
variance do not help in avoiding such biases. A revisited version of this paper was published in the Winter, 7(2) issue of Derivatives Quarterly. More...
