The high quality of profit makes investors eager to make more investments. When investors are sure that the quality of the company's profit is high, they invest more in securities. One of the potential consequences of profit quality is the effect of information asymmetry. Information asymmetry increases the risk of incorrect selection and as a result reduces liquidity in financial markets, and its relationship with the quality of profit is important for financial analysts, investors and other people.

The statistical population of this research is the companies accepted in the Tehran Stock Exchange and its statistical sample includes the data of 105 companies for the 5-year period of 2016-2019.

The research results showed that profit quality has a negative and significant effect on information asymmetry. Also, the results showed that the audit partner's industry expertise strengthens the negative and significant effect of profit quality on information asymmetry. Other results showed that the audit firm's industry expertise strengthens the negative and significant effect of earnings quality on information asymmetry.
