Nabil Sifouh, Khadija Oubal, Sara Bayoud


The purpose of this paper is to measure whether the investor operating on the Casablanca Stock Exchange displays a behavior of overconfidence, and to examine, under this hypothesis, the role of overconfidence in the explanation of fluctuations in the value of the MASI benchmark index over a 16-year period from 2002 to 2017.
