The stock market liquidity is very important due to its various roles and effects in the capital market and plays an important role in the stock market quality. On the other hand, the Stock price synchronicity reflects the amount of market information relative to specific information in the stock price of the companies. some studies have examined the effect of stock market liquidity on Stock price synchronicity and other studies that test the effect of the Stock price synchronicity on stock market liquidity. Therefore, the present study examines the relationship between stock market liquidity and Stock price synchronicity in listed companies in the Tehran Stock Exchange during the period from 2008 to 2015. In this study, 66 companies were selected as samples Using a systematic Omissive method and for the simulation of Stock price synchronicity, the model presented by Piotroski and Roulstone (2004) has been used. Then simultaneous equations system was estimated using a two-step regression method. The results of the estimation indicate the existence of a two-way relationship between the Trading volume, stock turnover, the stock market illiquidity ratio (Amihud), and the Amivest liquidity ratio as the criteria for assessing stock market liquidity and Stock price synchronicity in Tehran Stock Exchange.
