In competitive markets, companies try to reach more shares of the market. In current paper, we investigated impact of information asymmetry on relationship between market share and rate of liquidity in companies listed in Tehran stock exchange during 2006 and 2011. In this research, 7 industrial groups were investigated as the sample and related data were analyzed.We used regression patterns in order to test hypotheses and liquidity was based on market share and asymmetry information. The results indicated that significant and positive relationships exist between market share and rate of liquidity. In other words, by increasing market share, rate of liquidity will be raised. Furthermore, result of coefficient indicated that size (controlling variable) showed a significant and positive relationship between size and liquidity. Consequently, share of bigger companies had more ability of liquidity. On the other side, by entering of information asymmetry variable to test hypothesis; amount of relationship between liquidity and market share will decline.
