Abstract The purpose of this research is to investigate the relationship between quality of accounting information, stock price delinquency and future stock returns. The poor quality of accounting information implies a reduction in quality of firm's information environment, increase in market friction in the form of information asymmetry, inadequate information and liquidity reductions. When market response to information is slow, it is said that there is a kind of time delay between providing information and reflecting on firm stock prices. For this purpose, 99 firms from Tehran Stock Exchange were selected through a screening technique in 11 years (2016–2006). Research variables have been analyzed using multivariate regression. By conducting F Lemmer and Hausman tests to determine the most appropriate regression model, we have tested hypotheses through pool and panel data. The findings of this research showed that quality of accruals has a significant direct and relationship with delay of stock price, and there was also no significant relationship between accounting information quality and abnormal stock returns.
