This study examines the impact of the managerial ability on the value relevance of accounting information in the Egyptian environment. Therefore, In the light of stock markets' main focus on accounting information and what value relevance represents for such information is an important standard to judge whether it is good or not. So, the current research uses (Ohlson, 1995) model to measure and evaluate the value appropriateness of accounting information in the Egyptian market as it is considered one of the leading models in this field; while testing the managerial ability of Chief Executive Officers (CEOs) through the measure which was developed by the study of (Demerjian et al., 2012) as one of the determinants of the value relevance of accounting information; which did not receive sufficient empirical concern from previous studies in this field. So that the current research will depend on two regression equations, the first is based on stock prices while its returns represent the other equation. Based on 60 firms representing the research community from Egyptian firms, distributed across different sectors, during the period 2009-2017 which including 540 observations. Using two models for the regression equations, the first is (Fixed Effect Model) for price regression, and the second is (Random Effect Model) for regression of returns. As indicated by the results of statistical tests in this regard; although the research found that through the measure (R2) there is an increase in the explanatory ability for both models after the inserting of the (managerial ability) variable, which means there is a significant improvement in the value relevance of accounting information with the inclusion of this variable. However, through the T-Test, the research reached the significance of the influence of the managerial ability on the value relevance of the earnings per share - as one of the information referred to in (OM) -in the two models of the research, and the lack of significance of its effect on the value relevance of the book value of the share - as one of the other information in (OM)- to make this significant effect of the book value of share on stock prices and returns is important in the interpretation of the study. The statistical results stated that there is value relevance for the variable of the book value of share separately from the variable of managerial ability “in terms of stock prices”, and its lack of significant effect in the returns model.
