Several phenomena are at the origin of the stock exchange crises and the mimetic aspect of the behaviours of the investors would prevail on the fundamental analysis of the values. In this direction, the interpretation of information seems to play a central role in these particular events. One of the innovations of the current crisis is related to a world legislative alignment of financial accountancies. Standards IAS-IFRS would have had procyclic effects generated by a "legal herd behaviored". Fair Value [Chatelain and Levy 2007] and the pricing of the financial instruments, appeared to be one of the principal sources of the crisis.
