If the information asymmetry exists، some investors have private and confidential information about companies more and better than other investors .Information asymmetry cause inefficient information flow which can influence company's future returns. This study investigates the impact of information asymmetry and the company's life cycle on future stock returns. With a sample of 670 firms - year regarding 67 companies listed in Tehran Stock Exchange during the period 1380-1389, we tested the hypothesis using multivariate linear regression model based on panel data. The findings of this study indicate that there is a significant negative relationship between information asymmetry and futures stock returns. In fact, with increasing asymmetry of information, future returns of stocks of companies decreased. Another result of study shows there is a significant positive relationship between year life cycle and future stock returns. In other words, with the increase in corporate life, the future stocks returns also increases.
