Independent Factor Autoregressive Conditional Density Model

In this article, we propose a novel Independent Factor Autoregressive Conditional Density (IFACD) model able to generate time-varying higher moments using an independent factor setup. Our proposed framework incorporates dynamic estimation of higher comovements and feasible portfolio representation within a non-elliptical multivariate distribution. We report an empirical application, using returns data from 14 MSCI equity index iShares for the period 1996 to 2010, and we show that the IFACD model provides superior VaR forecasts and portfolio allocations with respect to the Conditionally Heteroskedastic Independent Component Analysis of Generalized Orthogonal (CHICAGO) and DCC models

Une application de la formule de Jarrow et Rudd aux options sur indice CAC 40.

L'objectif de cet article est de verifier s'il est possible d'ameliorer l'evaluation des options sur indice CAC 40 grace a une meilleure estimation des parametres d'asymetrie et d'aplatissement de la fonction de distribution de l'actif sous-jacent.FIXATION DU PRIX ; MODELES ; PREVISIONS
