The FBF "Structured Products and Derivatives" Research Chair

The Fédération Bancaire Française (FBF) "Structured Products and Derivatives" Research Chair is under the scientific responsibility of Lionel Martellini, Scientific Director of EDHEC-Risk Institute.

The objective of the FBF Structured Products and Derivatives Research Chair is to examine structured products with regard to clients' specific requirements.

The research chair will focus on three research projects:

  • The optimal design of structured products.

  • Structured products and derivatives in active/passive management.

  • Structured products and derivatives on underlying instruments that are illiquid or lack liquidity.

The FBF (French Banking Federation) will support the research chair over a five year period. This research chair, which was awarded to EDHEC-Risk Institute, was one of five high-level research chairs in the field of corporate and investment banking offered by the FBF to increase the competitiveness of the French financial market.

In 2013, as the previous research chair on "Structured Products and Derivatives" draws to a close, FBF will be supporting a new research chair at EDHEC-Risk Institute, entitled "Innovations and Regulations in Investment Banking", which aims to provide advanced research in four areas: skewness as an asset class; corporate and sovereign credit default swap (CDS) markets; the evaluation of policies to regulate financial markets; and options on liquidity.

Analysing Statistical Robustness of Cross-Sectional Volatility
August 2013
Felix Goltz, Lionel Martellini, Stoyan Stoyanov
This paper proposes a robust method of estimation which is intuitive and is functionally similar to the weighted-average estimator studied by Garcia, Mantilla-Garcia and Martellini (2013) in the context of one-factor and multi-factor regression models. To meet this objective, we adopt a statistical technique called M-estimation.

The Relevance of Country- and Sector-specific Model-free Volatility Indicators
March 2013
Lixia Loh, Lionel Martellini, Stoyan Stoyanov
This paper tests for the presence of local volatility factors using model-free volatility indicators in contrast to the classical model-dependent approach through GARCH-type processes. It employs three different model-free methodologies – model-free option implied volatility (MFOI), realised volatility, and cross-sectional volatility (CSV). Although MFOI volatility relates to market expectations about future volatility levels, both MFOI and realised volatility represent systematic volatility measures. In contrast, CSV represents a measure of aggregate specific volatility which is, however, not empirically disconnected from the market index return.

Idiosyncratic Risk and the Cross-Section of Stock Returns
February 2011
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. Two key advantages of this measure are its model-free nature and its observability at any frequency, which allows us to present new results on the properties of daily idiosyncratic volatility series. Through central limit arguments, we formally show that the cross-sectional dispersion of stock returns can be regarded as a consistent and asymptotically efficient estimator for idiosyncratic volatility. We empirically confirm that the cross-sectional measure provides a very good proxy for average idiosyncratic risk as implied by standard asset pricing models and that it predicts well aggregate returns, especially at the daily frequency. The predictability power of idiosyncratic risk is further increased when adding a measure of cross-sectional skewness to the cross-sectional variance factor. We finally provide evidence that idiosyncratic risk is a positively rewarded risk factor.

Option Pricing and Hedging in the Presence of Basis Risk
February 2011
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.

Option Pricing and Hedging in the Presence of Cross-Hedge Risk
June 2010
Lionel Martellini, Vincent Milhau
This paper addresses the question of option pricing and hedging when the underlying asset is not available for dynamic trading, and some other asset is used as a substitute. It first provides an overview of the various hedging methodologies that can be used in this incomplete market setting, distinguishing between self-financing and non-self-financing strategies. Focussing on a local risk-minimization criterion, it presents an analytical expression for the optimal hedging strategy and the corresponding option price. It also provides a quantitative measure of the residual risk over the life of the option. The paper finds that the use of the optimal strategy induces a much smaller replication error compared to the replication error induced by a naive Black-Scholes strategy, especially for low levels of the correlation between the underlying asset and the substitute. In the absence of transaction costs, it also finds that cross hedge risk is more substantial than the risk induced by discrete trading for reasonable parameter values. While this result implies that trading in the substitute can only be rationalised for exceedingly high correlations, the presence of (higher levels of) transaction costs is likely, however, to make trading in the actual underlying asset a prohibitively costly alternative.

The Benefits of Structured Products in Asset-Liability Management
December 2008
Lionel Martellini, Vincent Milhau
This paper introduces a continuous-time dynamic asset allocation model for an investor facing liability constraints in the presence of inflation and interest rate risks. When funding ratio constraints are explicitly accounted for, the optimal policies, for which we obtain analytical expressions, are shown to extend standard Option-Based Portfolio Insurance (OBPI) strategies to a relative risk context, with the liability-hedging portfolio replacing the risk-free asset. We also show that the introduction of maximum funding ratio targets would allow pension funds to decrease the cost of downside liability risk protection while giving up part of the upside potential beyond levels where marginal utility of wealth (relative to liabilities) is low or almost zero.

 Présentation : Une meilleure mesure de la volatilité pour une meilleure gestion des risques
12 décembre 2011 - Paris

Les informations sur les fluctuations de volatilité étant d’une importance primordiale pour les acteurs du marché, plusieurs initiatives ont récemment été lancées afin de mettre des mesures de volatilité à la disposition des investisseurs dans la forme d’indices de volatilité.

Dans le même temps, on constate que dans le cadre d’une allocation d’actifs stratégique, la prévisibilité des rendements peut être perturbée par des changements importants dans la volatilité des cours d’actifs. Un bon modèle statistique pour capter ces perturbations est le modèle à changement de régime de Markov.

Dans le cadre de la chaire « Produits Structurés et Produits Dérivés » de l’EDHEC-Risk Institute, soutenue par la Fédération Bancaire Française, les professeurs Lionel Martellini et René Garcia de l’EDHEC présenteront les résultats de leurs derniers travaux dans ces deux domaines et démontreront la pertinence de ces recherches pour les professionnels de la finance.

 Séminaire : Les innovations et la régulation dans la banque d'investissement
17 janvier 2013 - Paris

La nouvelle chaire de recherche sur les innovations et la régulation dans la banque d’investissement conduite par l’EDHEC-Risk Institute avec le soutien de la Fédération Bancaire Française (FBF) se décline sur quatre thèmes principaux : la skewness en tant que classe d’actifs ; l’analyse du marché des contrats d’échange sur risque de crédit (CDS) souverains et d’entreprise ; l’évaluation des politiques de régulation des marchés financiers ; et les options sur la liquidité.

Lors d’un atelier d’une demi-journée le 17 janvier, 2013, dans les locaux de la FBF à Paris, le Professeur Lionel Martellini, Directeur Scientifique de l’EDHEC-Risk Institute, introduira cette nouvelle chaire de recherche et présentera ses futurs travaux. Une présentation du Professeur Raman Uppal, de l’EDHEC Business School, sur l’évaluation des politiques de régulation des marchés financiers, sera ensuite suivi par une discussion animée par Jean Tricou, Directeur du département Banque d’investissement et de marché de la FBF. Enfin, une présentation de Dominic O’Kane, Professeur de Finance Affilié à l’EDHEC Business School, analysera de manière approfondie le marché des CDS souverains et d’entreprises ainsi que son utilité économique. Cette présentation sera commentée par deux des membres du comité scientifique de la chaire de recherche de l’EDHEC-Risk Institute : Thierry Roncalli, Responsable recherche et développement de Lyxor Asset Management, et Michel Crouhy, Responsable de la recherche et du développement de Natixis.
