The aim of this research is to investigate the explanatory power of asset turnover (ATO)/Profit Margin (PM) model in determining of changes of operating income of listed companies in Tehran Stock Exchange. Dependent variable is ratio of changes of operating income to net operating assets in forward year that is used to measure the information content of ATO/PM model in identifying earnings management. In this study, we propose a simple diagnostic of earnings management that relies on the widely held notion underlying DuPont analysis that sales is a fundamental driver of a firm’s investment and income, and that net operating assets on the balance sheet and net operating income on the income statement should vary directly with sales. Moreover, we note that changes in ATO and PM in opposite directions could signal earnings management. Independent variables contain upward and downward EM based on ATO/PM model. Also, operating income to net operating assets ratio in current year, changes of operating income to net operating assets ratio in current year, to net operating assets to sale ratio in current year, changes of net operating assets to sale ratio in current year, changes of ATO, changes of PM, components of managed accrual items based on abnormal accrual items (Jones adjusted Model), and market value to book value were applied as control variables. Statistical population contains 133 companies during 2004-2011. The panel/pooled regression models exerted to testify research hypotheses.
Findings indicate that ATO/PM model compared with Jones adjusted abnormal accruals items model is of less relative information content in identifying earnings management.

In this research, the effect of firm size, current ratio Total liabilities/ total assets ratio and accounts receivable/total assets ratio variables on qualified audit report and relationship between previous year's audit report and audit firm’s type with qualified audit report were investigated. By investigating the qualified and unqualified audit reports for Tehran stock exchange firms during 1381-1383, the information of 144 firms were collected. The results of Logit regression and chi-squared independence test show that the current ratio and accounts receivable/ total assets ratio affect the qualified audit report. However, it shows that there is a significant relationship between previous year’s audit report and audit firm’s type with qualified audit report. But, firm size and total liabilities/total assets ratio have no effects on the qualified report.

After initial Pricing of stocks at Tehran stock exchange, security prices will fluctuate according to the market prices. The question is which theoretical model, the market price of securities, will follow? The aim of this study is to identify among the best theoretical models, a model, which can best define the market price.
In this research, three valuation models which are best recommended in financial management literature are chosen, and the stocks which are traded at Tehran stock exchange are valued by them. Then the actual security prices, revealed by market are compared with those calculated values. The results of this study shows that if the required rate of return is calculated by CAPM, the Walter model compared to Gordon growth model and present value model of future cash flows, calculate security values closer to the market prices of the securities. The results also indicate when the fixed required rate of return of 40% is used; Gordon growth model will give values closer to the market prices of the securities.
