In this study, the impact of CEO’s overconfidence on the relationship between cash holding and excess returns is investigated in companies listed in Tehran Stock Exchange during the years 2011-2018. For CEO’s overconfidence, overinvestment in assets, and for excess returns, the difference between a firm’s stock return and the return of the firm’s benchmark portfolio over the same period is used. By systematic sampling, a sample of 157 companies is selected, and the models have run based on panel data with fixed effects. The results have shown that (1) cash holding has a positive and significant impact on excess returns, (2) CEO’s overconfidence has a negative and significant impact on excess returns, and lastly, (3) CEO’s overconfidence has a negative and significant impact on the relationship between cash holdings and the excess returns. With increasing CEO’s overconfidence, the excess returns will be reduced. Overconfident managers keep cash at a higher level that leads to overinvestment. It consequently decreases excess returns.
