Abstract
This paper investigates the information content of some accounting variables and degree of their association with risk and return by residual income model in Tehran stock exchange (TSE). In order to determine risk factors, we use Fama and French (1992) three-factor Model. The first contribution is that the fundamental value based on accounting figures, is highly correlated with stock prices, that is, the accounting numbers as residual income and book value and the fundamental value based on them, are important factors determining the market value of stocks. Our results indicate that beta coefficient cannot explain price differentials, and price differentials are not related to abnormal return. We further document that relative information content of price differentials and Systematic Risk are different. Finally, we find that price differentials with systematic risk do not contain incremental information content to explain returns in TSE.
