Investigating the Effect of Specific Charecteristics of Firms on the Relationship between Working Capital Accruals and Volatility of Stock Return

In this research, the relationship between working capital accruals and volatility of stock returns in listed companies in Tehran Stock Exchange has been investigated. The sample of this research includes 156 companies admitted to Tehran Stock Exchange during the period from 1388 to 1394. A multivariate regression model was used to analyze the data and test hypotheses. The results show that volatility of stock returns has no significant effect on working capital accruals. Also, the financial distress does not have a significant effect on the relationship between volatility of stock returns and working capital accruals. But the company's operating cycle has a significant effect on the relationship between volatility of stock returns and working capital accruals. Also, the sensitivity of asset component of working capital versus debt component of working capital versus stock return volatility varies. The results of this research are similar to those of Aref et al (2016).
