One of the most important aspects of investing is the risk of that investment. considering systematic and unsystematic risk as total risk, a part of risk that not deleted by diversification is called systematic risk. The purpose of this research is a comparison between two criteria of systematic risk assessment, the fundamental beta and historical beta. before that, the effect of financial statements information on the historical beta is investigated. For this purpose, the data of 33 companies that is selected by sifting method were collected during the period 1386-1395 using econometric methods of time series and pooled data. The results show that among the 7 accounting variables tested in this study (financial leverage, operating leverage, liquidity, fluctuation of earnings per share, percentage of dividend, size, and growth), 3 variables, namely, financial leverage, liquidity and size of firm affected The historical beta, and the historical beta, despite easiness in calculation, has a better performance than fundamental beta
