The study begins with reviewing the Efficient Market Hypothesis (EMH) and the theory of Behavioral Finance. Theoretically, markets are efficient and investors are rational under EMH theory; however, it is found that many markets are not following the rules of EMH and a question whether people tend to behave logically and rationally has raised with the appearance of market anomalies. This is where the Behavioral Finance theories started to originate studying the psychological biases that affect decision making. Researchers have found that investors are irrational and overconfident about the precision of their skills and knowledge. Study hypotheses are proposed and then tested through questionnaires distributed to individual investors at Beirut Stock Exchange using quantitative method.
