In this study, the financial information’s qualitative characteristic was used for evaluating earning quality. Regarding to limitations, we examined 85 firms accepted in Tehran Stock Exchange in 1375-1384 period. At first, dimensions of relevance and reliability of earning for all of sample firms, was estimated by using of Time series and Panel data analysis. Then, the firms with cluster analysis method, was classified, and firms with high and low earning quality was segregated. Finally, Ohlson’s price-earning regression for test hypotheses was applicator. The result show that earning response coefficient and explanatory power of earnings are significantly higher in portfolios of firms with high quality earnings compared to firms with low quality earnings. Therefore, all of hypotheses were accepted. In this study was shown that, the earning quality reflects decision usefulness to investors.

The anticipating models could be helping the investor and other usages to prognosis the investing efficiency from analysis and techniques.

The research uses a leverage-based approach for investigation about the ability of book-to-market ratio for risk proxy. On the past researches and used model (pooled regression) and approach, we expected that effect of this ratio on historical stock returns, should be result of book leverage and market leverage factors.Our results confirm applied model. Therefore, book-to-market effect relates to market leverage and book leverage, and could be a proxy for risk.

In this article we investigated the role of accruals in interpreting earnings quality in Tehran Stock Exchange (TSE), and the relation between earnings quality based on accruals and it's components with normal and abnormal returns By using data from TSE over period 1377-1384 (Iranian calendar). We separated accruals in discretionary and nondiscretionary items.In order to obtain the relation between earnings quality and stock returns six hypotheses have been analyzed. We suggest that stock returns affected by extent of accruals and its components. Furthermore stock returns of companies with high accruals and low accruals have been related together significantly.

In this paper we investigate the relation between asymmetric timeliness of earnings and the market to book ratio by using data of firms listed in Tehran Stock Exchange (TSE). The difference between the coefficients of earnings on positive and negative returns is called asymmetric timeliness of earnings. In the accounting literature it is used as a conservatism measure. The recent literature focused on the negative relation between two measures of conservatism: asymmetric timeliness of earnings and the market to book ratio (MTB) in short periods. We expected this relation would be positive when asymmetric timeliness of earnings measured cumulatively over long horizons. The result inconsistent to our predict show negative relation between two measure of conservatism that statistically significant.

This study is designed to provide insights into the monitoring role of institutional investors by examining whether institutional ownership affects the corporate value. Prior studies examining the relation between the shareholdings by institutional investors and corporate value have produced mixed results. In this study, different hypothesis (Effective Monitoring Hypothesis & Convergence of Interest Hypothesis) in relation to institutional investors, are tested. A multifold linear regression analysis is used to test the relation between corporate value and institutional ownership. The results demonstrate significant evidence of a positive association between institutional ownership and corporate value and approve Effective Monitoring Hypothesis. In addition, this study does not find significant linear relationship between concentrated institutional ownership and corporate value and Convergence of Interest Hypothesis is not approved.
