    Abstract

    Plusieurs phénomènes sont à l'origine des crises boursières et l'aspect mimétique des comportements des investisseurs prévaudrait sur l'analyse fondamentale des valeurs. En ce sens, l'interprétation de l'information semble jouer un rôle central lors de ces évènements particuliers. Une des nouveautés de la crise actuelle est liée à un alignement législatif mondial des comptabilités financières. Les normes IAS-IFRS auraient eu des effets procycliques engendrés par un " mimétisme légal ". L'évaluation à la Juste Valeur et la valorisation des instruments financiers, ont paru être les principales courroies de transmission de la crise.
