The Effect of Overconfidence Bias on Investors Decisions in the Egyptian Stock Market: The Role of Information Acquisition

Abstract

The aim of this paper is to empirically test the relationship between overconfidence bias on investor decisions. This paper also contributes to a better understanding of the role of information acquisition in moderating the relationship between behavioral biases and investor decisions. The findings confirm that behavioral biases (overconfidence bias) distort the rationality of individual investors' decisions, and that information acquisition significantly moderates the relationship between overconfidence bias and investor decisions. This study adds to the existing behavioral finance literature by highlighting the underutilized potential of information acquisition in managing irrationality caused by overconfidence bias. Individual investors can benefit from this study by better understanding the negative impact of behavioral biases as well as the utility of information acquisition in dealing with irrationality caused by overconfidence bias. The study attempts to combine behavioral finance and information acquisition literature with an aim concept to extend a theoretical understandings of investor decisions.
