Abstract

This article tries to examine the efficiency market hypothesis. Therefore, the efficiency is studied through endogenous and exogenous information. The goal of this paper is to describe the literature review the most exhaustive of effi iency studies. We show that distinct conclusions can be emphasized following the type of analyzed information. 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
