Chance of our ignorance, lack of information which prohibits predict what the future brings, and the existence of multiple causes that cross the path of winning anyway, all this creates major undesirable effects of this that financial institutions have fully made the effort to graduate uncertainty or rather determine the predictability that now was mathematical statistics and not deterministic form. Among the methods most used in the context of risk management in finance is the Value at risk. This method allows materializing the risk of losing a position or the entire portfolio. The goal of this paper is to clarify some notions about this approach and to have more ideas and trace while giving tracks to highlight the risks, corrected to overcome weaknesses and to better understand the fluctuations. Thus we would calculate the Value At Risk of a diversified portfolio composed of three assets.

Abstract: (french)

Le hasard de notre ignorance, le manque d'information qui interdit de prédire ce que l'avenir apporte, et l'existence des causes multiples qui croisent le chemin du gain de toute manière, tout cela engendre de grands effets non souhaitables, de ce fait les institutions financières ont pleinement fait l'effort afin de graduer l'incertitude ou plutôt déterminer la prédictibilité qui désormais fut statistique mathématique et non pas déterministe. Parmi les méthodes les plus utilisé dans le cadre de la gestion des risques en finance est la Value at risk. Cette méthode permet de matérialiser le risque de perte d'une position ou de l'ensemble d'un portefeuille. Le but de ce papier est de clarifier quelques notions sur cette approche et d'en avoir plus d'idées et de traces tout en donnant des pistes permettant de souligner les risques, les corrigées afin de surmonter les faiblesses et de mieux appréhender les fluctuations. Ainsi nous calculons la Value At Risk d'un portefeuille diversifié composé de trois actifs.
