This paper studies the cash flows forecast models and compares the predictive ability of models based on absolute forecast error. Also in this paper, as the indicator of volatility of business environment, the effects of volatility of sales and volatility of operating profit have been used and the effect of firm size on predictive ability of each model has been considered.
In order to study above mentioned, three following hypotheses have been tested in this paper:
Hypothesis 1: the predictive ability of future cash flows based on accruals models is more than those models which only use the cash flows information.
Hypothesis 2: the predictive ability of accruals based models and those models which only use the cash flows in their predictions, change as volatility of sales and volatility of operating profit.
Hypothesis 3: the predictive ability of accruals based models and those models which only use the cash flows in their predictions, increase as the firm size increases.

In this study we investigate the possibility of earning abnormal returns through the use of contrarian trading strategy in Tehran Stock Exchange (TSE). Contrarian trading strategy states that stocks which had better performances in the past, should be sold and stocks that had poor performances, should be bought. This strategy is based on the belief that capital market shows overreaction to the recent information and determines the price of Winner stocks more than their real value and the price of less Losers than their real value. Consequently in the subsequent periods, market will recognize its mispricing and return reversal will be observed in these stocks. Five major industries of Tehran Stock Exchange (TSE) which were studied between the years of 1379 to 1384, formed statistical sample of this study. Statistical Method of T-test were used to analyze the gathered data. Results revealed that it is possible to increase return of investments on securities in the TSE through the use of contrarian investment strategy.

This paper investigates the value relevance of accounting information for firms’ market values prediction. In the study the value relevance of Book Values, Earnings, Operating Cash Flows and Investment Cash Flows as proxies of accounting information are investigated for equity valuation of companies listed in Tehran Stock Exchange (TSE). We examine fifteen models and four independent variables, as well as the explanatory power of these variables. If accounting information can be used as relevant variables in prediction models of firms’ market values then, the hypothesis of value relevance of accounting information can be accepted.
For examining the relationship between research variables and firms’ market values, four hypotheses, using four regression models, are tested. For more analysis, other eleven multiple regression models are used. Through examining the 15 models, we can select the superior model for ability of prediction.
For hypotheses testing, a sample of 50 companies listed in Tehran Stock Exchange (TSE) is selected. The dada needed for the study is gathered manually via a variety of resources. The pooled data for years of 2001-2006 and fifty companies listed in TSE are used.
