This study investigates the value relevance of operating income versus non
operating income at Iran capital market. Regarding the main objective of
accounting practice, value relevance is a concept that has always required more
attention by accountants and regulators. By definition a factor is relevant if its
reflection at asset market`s value is not negligible. For this study in the period
1379-1385 companies in each year and totally 581 company/year investigate.
We use regression and T test and Wald test. Our results show that operating
income is more relevant to the market. This result could be consistent with big
bath theory and as a result of market attention to management choice in order
to change non operating income; to achieve their objectives. Consequently the
non operating items have more relevant for the market.
