This is a descriptive correlational research and it uses post event methodology. For testing the hypothesis of the research, we've used ordinary least square regression model with panel data. The main hypothesis of this research is that the transparency can enhance firm's liquidity and valuation. For measuring transparency we've combined four proxies according to Lang et al. (2012): accruals quality, management EPS prediction deviation, auditor type and TSE's transparency scores. Also Tobin's' Q has been used as a proxy for firm valuation and mean of daily trading volume for measuring liquidity. After running the model, we’ve found significant and negative relationship between transparency and liquidity. Also there was no significant relationship between transparency and firm valuation.
