Investigating the performance of companies is one of the most important issues for the users of accounting information. The purpose of this study is to provide evidence about the effect of asymmetric appropriateness on investors' expectations. The results of the research on accepted companies listed in the Tehran Stock Exchange during the period from 2012 to 2016. To collect data, a library method was used and referring to financial statements, explanatory notes and monthly stock exchange of the Stock Exchange. Using Cochran sampling method, 120 firms were selected as the statistical sample. To analysis the data, multivariate regression analysis was used to confirm the rejection and research hypotheses (Eviews software). The results showed that asymmetric accountability leads to different expectations of investors about the Corporate Perspective, and the negative relationship between asymmetric verification (conservatism) and investors' controversy is weaker with the release of good news and gets worse by the publication of bad news. The results are consistent with the documentation referred to in the theoretical framework of financial research and literature, such as the theory of Corporate Perspective and the concepts of behavioural and financial behaviour, and the publication of good and bad news has a significant role.
