In general, investor behavior has an important place in the valuation of the rights of the owners of an economic unit. Therefore, several studies have concluded that investor behavior based on financial information (including accounting profit) will lead to changes in the price and return of the economic unit's stock. In this regard, the main goal of this study is to evaluate and compare the power of the initial and optimized models (based on profit-related perspectives) of accounting information value. In the present study, to obtain the index and power of the initial and optimized models, 170 companies listed on the Tehran Stock Exchange were examined in the period 1393-1402. In this regard, paired t-tests and Wong's difference tests were used to test the research hypotheses. The research findings show that there is a significant difference between the average power of the initial and optimized models and the average trend power (increasing/decreasing) of the initial and optimized models of accounting information value.
