The purpose of this research is to investigate the relationship between the disclosure of prospective financial information and the volatility of stock returns of companies listed on the Tehran Stock Exchange, as well as to investigate the effect of companies' good reputation on this relationship.

In order to achieve the goals of the research, two hypotheses have been developed that test the meaningfulness of the relationship between the disclosure of prospective financial information, the fluctuations of stock returns and good reputation in the companies listed on the Tehran Stock Exchange. Disclosure of prospective financial information was measured using content analysis method. The statistical method used to test the hypotheses presented in this research is the step-by-step regression analysis method, and the statistical sample of the research includes 120 companies in the years 2018 to 2022.

The results of the analysis of the research hypotheses show that the disclosure of forward-looking financial information leads to a decrease in the volatility of stock returns of companies listed on the Tehran Stock Exchange.

The present article explains the effect of some macroeconomic indicators on stock return fluctuations .Artificial exchange rate pricing in the years before the crisis and preventing it from adjusting to the economic conditions is one of the main reasons for the recent currency crisis. Also, the calculation of the foreign exchange market pressure index indicates that the highest numbers obtained for this index are related to the time when the gap between the free exchange rate and the official exchange rate has increased. The results also showed that the effect of exchange rate fluctuations on stock return fluctuations is positive and significant, which indicates that there is a high correlation between stock returns and the exchange rate market. Also, the positive sign of the coefficient indicates a positive and significant effect of interest rates on the variability of stock returns. This result shows that higher interest rates have led to more fluctuations in stock returns. Finally, GDP per capita was not significant in any of the error levels of 1, 5 and 10%, which indicates that it did not have a significant effect on stock fluctuations.

The sample of this study consists of 102 listed companies in Tehran Stock Exchange during 2011 to 2019. In order to test the hypotheses, linear regression model and the panel data method have been used. The results of testing hypotheses indicated that there is a negative and significant relationship between the value of the firm and net working capital and the cash conversion cycle. Therefore, with an optimal working capital management and a reduction in the cash conversion cycle, the value of the firm can be increased. Results also showed that net working capital has no effect on stock return volatility.

The purpose of this study is to investigate the Relationship between multiple Earnings quality measures and stock return volatility. Research in terms of purpose is part of applied research and research method in terms of nature and content is cause and effect.

To collect information, data from 142 companies listed on the Tehran Stock Exchange in the period 1391-1399 have been used. The results of this study show that accrual quality and persistent earnings have a negative and significant relationship and conservatism and earnings smoothness have a positive and significant relationship with stock return volatility; But the relationship between profit predictability and stock return volatility is not significant

Corporate social responsibility is a key factor in the survival of any organization. Companies see social responsibility as a kind of business strategy, which increases their credibility in competitive markets and also increases their market share. . Liquidity risk and its management method has become one of the most important issues in organizations. The potential effects that this branch of risk can have on the performance of companies are sometimes so wide that they lead to the bankruptcy of these units. The present study investigates the relationship between corporate social responsibility, liquidity risk and stock return fluctuations of the Tehran Stock Exchange in the period 2015 to 2019. Sampling was performed using a systematic elimination method and The selected sample includes 140 companies. The model used in the research follows the study of Bechti et al. (2015) The results show that the liquidity risk variable has a positive and significant effect on stock return fluctuations. This means that with increasing liquidity risk, the amount of stock return fluctuations also increases. The effect of social responsibility variable on stock return fluctuations is negative and significant. Annual sales growth, company size and fixed assets have a negative and significant effect on stock return fluctuations. According to the results of both research hypotheses, the 95% confidence level is confirmed.

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).
