Accordingly, the statistical population under study of this research includes all companies admitted in Tehran Exchange Market form 2006- 2015. The present research method considering the current payment situation, is from descriptive- correlation type. In this research, both methods of gathering information including librarian and field methods are utilized. The required studies about research theoretical bases, research thematic literature, problem backgrounds and research subject have been made by librarian methods and for studying references, theses, and research about the subject internet bases have been used. Also the present research is included in survey researches, regarding its methods. In order to examine the hypotheses of this research, we used multivariate regression model. The findings of research shows the extrapolating capital assets pricing models (X-CAPM),companies admitted in Tehran Exchange Market, hasn’t had high explanatory capability relative to other models, i.e. capital assets pricing models (CAPM), for instance reductive- undesirable capital assets pricing models (D-CAPM), adjustable capital assets pricing models (X-CAPM), interperiod capital assets pricing models, conditional capital assets pricing models (I-CAPM), revised capital assets pricing models (R-CAPM), consumption-based capital assets pricing models (R-CAPM), rewarding capital assets pricing models (RRM), behavioral capital assets pricing models (BAP
