Les marchés financiers sont-ils rationnels ?
Due to the recent stock market crises, many economists have been keeping aloof from the « core» of financial theory, whose main contention is that stock market prices are at any moment the best possible estimate of the « true» value of the issuing firms. Most of those economists have brought forward, in a way or another, the hypothesis that markets suddenly get crazy. This contribution, based on both observa~tion of the recent financial history (the crash of the « New Economy» securities) and results from « experimental economics», and using the complementary concepts of « mimicry» and « convention » to account for « self-referential dynamics», is opening a third way of thinking the efficiency problematic: investors fix their strategy based on the estimates of the other participants, even if they strongly believe they are wrong.

Consequently, the endogenous information is not of quality to question the efficiency, rather than the exogenous one shows significant results. The exogenous information allows forecasting future stock returns, and earning profit. It is getting a decision making tool. JEL Classification: G00, G14
