  This study examines the effective factors in bid ask spread as a measure for information asymmetry among listed firms in Tehran’s stock exchange. In this study, the effect of share’s liquidity risk variables, market liquidity risk, , market liquidity, number of transactions, and trading volume of bid ask spread is investigated. In this line, five hypotheses were suggested. A sample consisting of 107 firms (642 firms-year) among the Listed Firms in Tehran’s Stock Exchange (from 2007 to 2012) were collected and tested through combined data method to test the hypotheses. The results verify the first and second hypotheses in that the number of transactions and trading volume has significant relationship with bid ask spread.  However, no relationship was found to be between liquidity risk, market liquidity risk, and market liquidity with bid ask spread.

Earnings forecasting by management is widely used in assessing profitability, profit-related risk, stock price judgments, and valuation models (Manfred & Inky, 2014). Our purpose in this study is to investigate and investigate the impact of dimensionality trading strategies on predicting daily stock market returns by the fuzzy logic approach of firms. This study is a library-analytic-causal study based on panel data analysis (panel data). In this study, the financial information of 19 companies listed in Tehran Stock Exchange during the period 2011-2018 was reviewed. The results showed that using stock trading strategy and stock price reduction strategy have significant effect on prediction of daily stock market returns, but trading volume reduction strategy has no significant effect on market forecasting.
