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.

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.
