Un MEDAF à plusieurs moments réalisés

Cet article généralise l'approche de Bollerslev et Zhang (2003) qui consiste à utiliser des mesures et co-mesures de risque « réalisées » pour l'estimation des sensibilités dans les modèles d'évaluation des actifs financiers. Nous proposons ici d'étendre cette approche en introduisant les moments d'ordre supérieur et développons des méthodologies d'estimation visant à neutraliser les erreurs de spécification et de modèle. A partir d'une base de données des prix de haute fréquence du marché français des actions, nous établissons que le recours à des mesures réalisées d'ordre supérieur contribue à améliorer l'ajustement global aux données de marché. / This paper generalizes the Bollerslev and Zhang (2003) approach for the estimation of loadings of asset pricing models using “realized” measures and co-measures of risk. We propose here to extend this approach by including higher-moments in asset pricing models. Estimations are conducted using several methodologies aiming to neutralize data measurement and model misspecification errors, explicitly dealing with the inter-relations between financial asset returns. An empirical application performed on a high-frequency French stock price database shows that realized higher-moment measures contribute to improve the global adjustment of the extended model with market data.
