The purpose of this study is to investigate the effect of real profit management in increasing the risk of falling stock prices by considering the role of managers' overconfidence. The current research is applied and from the methodological point of view, the correlation is causal type (post-event). The statistical population of the research is all the companies admitted to the Tehran Stock Exchange and using the systematic elimination sampling method, 146 companies were selected as the research sample and were examined in a 6-year period between 1396 and 1401. The results of the research hypotheses test showed that profit management has an effect on the risk of falling stock prices and managers' overconfidence moderates this relationship.

With the increasing expansion of joint-stock companies and the diversification of their capital structure on the one hand and the emergence of severe financial crises in the macro and micro dimensions on the other hand, the owners and various stakeholders of the companies are trying to create a cover and shield to protect themselves against These are the risks and this issue has led them to use predictive tools and models to evaluate the financial strength of companies. Based on this, the purpose of this research is to investigate the impact of economic uncertainty and the risk of falling stock prices with regard to the role of mediator. be intellectual capital. The current research is practical in terms of its purpose, and in terms of method, it is a causal (post-event) type of research. The statistical population of the research was the companies admitted to the Tehran Stock Exchange, using the method of systematic elimination, 144 companies were selected as the research sample in the period between 1394 and 1401. To test the research hypotheses, logistic regression was used using Eviuse software. The results of the research showed that economic policy uncertainty has a significant effect on the risk of falling stock prices, and intellectual capital has a mediating role on the relationship between economic uncertainty and the risk of falling stock prices. On the other hand, human capital, structural capital and physical capital also have a mediating role on the relationship between economic uncertainty and the risk of falling stock prices.

The relationship between corporate social responsibility disclosure and stock price risk is complex due to regulatory effects, indirect effects, and uncertain effects of some intervening factors. The purpose of this research is to investigate the relationship between social responsibility disclosure and stock price risk, considering the role of the company's performance moderator. The information required for this study is taken from the financial statements of 168 companies in the period 1393-1400. In terms of purpose, the research is part of applied research and the research method is correlational in terms of nature and content, and panel analysis has been used to analyze the hypothesis. The results showed that there is a negative relationship between the disclosure of social responsibility stock price risk; But this relationship is not significant; Also, the company's performance does not affect the relationship between social responsibility disclosure and stock price risk. This negative relationship is consistent with the balance theory, which suggests that companies that actively practice their social responsibility are more likely to disclose more information, increasing transparency and reducing information asymmetry.

Investors and shareholders are two groups that have a special interest in risk and returns information. So, the effect of environmental performance on the risk of stock price crashes is the most important information that is considered by users. The present study examines the impact of companies' environmental performance on the risk of stock price crash with an emphasis on accounting conservatism in the Tehran Stock Exchange. This research is applied in terms of purpose and descriptive-correlational in nature. To achieve the research goal, 109 companies were selected from the companies listed on the Tehran Stock Exchange during the years 1390 to 1398 by systematic elimination sampling method and a total of 981 years of the company was considered for analysis. To study the relationships between variables, multivariate regression was used to fit the logistic regression pattern. Also, the combined data method was used to test the hypotheses. The findings show that environmental performance has a negative and significant effect on the risk of stock price crashes. But accounting conservatism as a moderating variable undermines this relationship

Customer relationship management encourages firms to attract and retain majority customers for future corporate transactions. However, greater dependency on majority customers results in certain risks for firms. As such, the present study is concerned with investigating the effect of customer concentration on the corporate stock price crash risk. in doing so, two measures of negative skewness of stock returns and bottom-up volatility are employed to compute stock price crash risk, and  Herfindahl-Hirschman Index serves to calculate customer concentration. The research hypothesis is built on a sample of 96  firms listed on the Tehran Stock Exchange during the years 2016-2020 and tested using multivariate regression model based on panel data. The results suggest that higher customer concentration results in the enhancement of stock price crash risk. moreover, the results of sensitivity analysis reveal that using an alternative proxy to measure customer concentration fails to exert any significant influence on the research results, thereby confirming the robustness of the findings.

The purpose of this study is to provide a model for measuring the moral hazard of managers based on financial data. For this purpose, based on the literature, theories, and surveys of experts across the country, 22 variables of the source of moral hazard of managers were extracted and re-exposed to the comments of experts to rate the variables in terms of importance. 9 variables were selected based on the preference of experts and using the group Analytical Hierarchy process (GAHP), appropriate coefficients were assigned to each of the selected variables and the initial model was obtained. Finally, the obtained model was validated through the identified consequences. The information of the final model, which includes the variables of ownership structure, environmental uncertainty, monopoly in the product market, financial constraints, leverage ratio, free cash flows, capital expenditures, internal risk of the company, and life cycle of the company, is collected from Tehran Stock Exchange. The relationship between the number obtained from the model and the consequences of moral hazards was investigated and it was found that there is a positive and significant relationship with information asymmetry and stock price crash risk and a negative and significant relationship with investment efficiency. As a result, the proposed model can be effective for decisions, especially in the capital market. By making it possible to measure the moral hazard of managers, the necessary measures can be taken to reduce it through the establishment of strong corporate governance mechanisms for control and supervision.

Investors and shareholders are two groups that have a special interest in the information on risk and returns. Thus, the effect of environmental performance on stock price crash risk is the most important information considered by users. The present study examined the impact of companies’ environmental performance on stock price crash risk with an emphasis on political connection in Tehran Stock Exchange (TSE). This study was an applied and descriptive-correlational research in terms of purpose and nature. To achieve the research goal, 109 companies were selected from among those listed on TSE during the years of 2011-19 via the systematic elimination sampling method and a total of 981 years of the companies was considered for analysis. To study the relationships between the variables, multivariate regression analysis was used to fit the logistic regression pattern. Also, the combined data method was utilized to test the hypotheses. The findings showed that environmental performance had a significantly negative effect on stock price crash risk, but political connections as a mediator variable had no effects on the relationship between environmental performance and stock price risk.

According to the research of Jebranet et al (2019), one of the factors that can affect the Stock Price Crash Risk of companies, is the Confucianism Culture (managers) that so far, this attention has not been considered in the financial and accounting research literature. Managers of companies based in Confucianism are more influenced by social norms and they spread bad news in a timely manner as a result, unethical managerial approaches (Moral hazards) are curbed, and even this will lead to the immunization of managerial behaviors, leads to a reduction in the Stock Price Crash Risk of companies and also institutional ownership be used as a corporate governance mechanism can weaken the negative relationship between the culture of Confucianism and the Stock Price Crash Risk of companies. Therefore, the purpose of this research is to investigate the Moderating role of Institutional Ownership on the relationship between Confucianism Culture and Stock Price Crash Risk. To achievement this research, Information on financial statements of 116 listed companies has been collected in the period of 2009 to 2020. To test the research hypotheses, the logit and multivariate regression model with panel data using fixed and random effects methods has been used. To measure the Confucianism Culture, the criterion of Geographical proximity-based from model Du (2015) has been used. The results show that there is not relationship between the Confucianism Culture and the Stock Price Crash Risk. Also, Institutional Ownership does not weaken the negative relationship between Confucianism Culture and the Stock Price Crash Risk of companies. The Stock Price Crash Risk does not realize the consequences of the Confucianism Culture which is due to the prevailing conditions in the Iranian capital market and also, the variable of Confucian culture is a new issue and its theoretical foundations as well as its importance have not been tangible or obvious to managers, shareholders and other stakeholders of companies. In Iranian companies, institutional ownership has not been able to play an effective role in explaining the relationship between the Confucianism Culture and the Stock Price Crash Risk.

The present study seeks to explain the effect of readability of financial statements on stock price risk and shareholder behavior. Readability of financial statements is expected to reduce the risk of falling stock prices, which can have a positive effect on shareholder behavior.

The statistical population of the present study is Tehran Stock Exchange. The required data has been extracted from Rahavard Novin database, the site of the Exchange Organization and the site of the Codal. Based on the screening, 89 units were selected and studied during the period 1390 to 1397.

The results show that there is a significant relationship between the readability of financial statements with the risk of falling stock prices and shareholder behavior. But the results of testing the third hypothesis showed that readability does not have a significant effect on the relationship between stock price volatility risk and shareholder behavior.

The results of this study suggest that the readability of financial statements affects the behavior of shareholders and this can affect the liquidity of stocks.

The present study examines the relationship between external financing activities, earnings smoothing and the risk of falling stock prices. This research is applied in terms of purpose and in terms of methodology of correlation is causal (post-event). The statistical population of the study is all companies listed on the Tehran Stock Exchange and using the systematic elimination sampling method, 120 companies were selected as the sample of the research in a period of 6 years between 2012 and 2017. The method used to collect information is a library and the relevant data for measuring variables were collected from the Cadal site and the companies' financial statements. The results show that there is a significant inverse relationship between earnings smoothing and the risk of falling stock prices. However, there is a positive and significant relationship between foreign financing activities and the risk of stock price falls. Also, foreign financing activities have a direct and significant effect on the relationship between earnings smoothing and the risk of falling stock prices.

Literature shows that increasing the quality of audit financial statements information increases the Accounting information comparability between peers’ firms. On the other hand, increasing comparability can also reduce the stock price crash risk. Using a panel data regression model, we explore the moderator role of audit quality on the relationship between the comparability of accounting information and stock price crash risk of 137 firms, for the period 2009 to 2018. The results showed that the earnings management as proxy of audit quality mitigates the severity of the negative and significant relationship between the comparability of accounting information and stock price crash risk. This can be due to upward earnings management. This conclusion is robust to the use of different control variables and econometric models. Present study contributes by providing theoretical and empirical evidence on auditing and finance literature. Keywords: Accounting information comparability, audit quality, earnings management and stock price crash risk

The stock price crash risk is always the inhibiting factor to attract liquidity on the capital market. Tehran stock exchange is at a lower level in terms of efficiency. Sudden changes of stock return have been observed. This will lead to liquidity transfer to non–productive markets including the Exchange of exchange and gold. The aim of this paper is to model the stock price crash risk in Tehran stock exchange. In this regard, the effect of factors such as cash management, financial distress, and disclosure quality and board composition were measured in the stock price crash risk. Also, the agency cost is considered as an intermediary variable. The statistical population of the companies listed in Tehran stock exchange is in the period from 1392 to 1396. To test the hypotheses, multivariate linear regression analysis and structural equation method are used. The results of the hypotheses tests show that, apart from the financial distress of other studied variables, the stock price crash risk is effective

The act of hiding and accumulating the bad news within the company by management has led to the creation of massive negative information. The sudden outburst of this news to the market would cause a stock price crash. In this regard, information disclosure about the risks faced by the company can lead to transparency of information and thus reduce the stock price crash risk. The goal of this research is to survey the effect of disclosure of risk and its types on stock price crash risk. In this study, 548 company-years during the period from 2011 to 2019 have been selected using systematic deletion method and research hypotheses have been tested using regression based on panel data with fixed effects. The results indicate that the disclosure of total risk has a negative and significant effect on the stock price crash risk. types of risk disclosures including financial risk, non-financial operating risk and strategic non-financial risk have a negative and significant effect on stock price crash risk.

Sentiment, as an inevitable factor, always affects stockholders’ transac-tions in the market and lead to incorrect stock pricing in the market. On the other hand, earnings management and providing unreal reports of company’s profitability can affect investors’ sentiment and encourage them to sell or buy the stocks. These may create stock price bubble and consequently increase the stock price crash risk. Thus the present rsearch, for the first time, investigate the association between investors’ sentiment and stock price crash risk with respect to the moderator role of earnings management. In this research, we use ARMS index and neg-ative coefficient of skewness in order to evaluate investors' sentiment and stock price crash risk, respectively, which the relationship between them is tested by the Multiple Linear Regression. Also, the statistical population of the study contains 102 accepted companies in Tehran stock exchange for the period between 2013 and 2018. The results show that the more positive and optimistic sentiment is, the more stock price crash risk we have. Also, the earnings management, as a moderator fac-tor, can reinforce their relationship.

The results showed that short-term sales restriction had an impact on the risk of falling stock prices and this is a positive effect. On the other hand, investment inefficiency has a positive effect on this relationship.

This study investigates the relationship between corporate innovation strategy and the risk of falling stock prices with emphasis on managers' behavioral factor. The purpose of this study is applied and is a causal (post-event) type of research methodology. The statistical population of the study consisted of all listed companies in Tehran Stock Exchange. Using systematic elimination sampling method, 114 companies were selected as the sample of the study. The method used for data collection was a library and logistic regression was used to test the research hypotheses. The results of the research hypotheses show that there is a significant inverse relationship between the firm's innovation strategy and the risk of falling stock prices.

Management ownership and more information by the company's management and the willingness of managers to disclose asymmetric news leads to a future risk of falling stock prices. The fall in stock prices has led to a sharp drop in returns. The purpose of this study is to investigate the effect of management ownership on the risk of future stock price collapse in companies. For this purpose, the data of 115 manufacturing companies accepted in Tehran Stock Exchange during the years 1390-1395 were analyzed. The result of estimating research models using combined data shows that there is a direct and direct relationship between management ownership and the risk of falling stock prices, that is, with the increase of management ownership, the risk of falling stock prices increases. In addition, the cost of representation affects the relationship between managerial ownership and the risk of falling stock prices. This means that the impact of managerial ownership is on the increased risk of future stock price collapse in companies with higher representation costs

The purpose of the present study is to investigate the effect of financial constraint on the risk of stock price collapse by emphasizing the moderating role of tax avoidance and corporate governance in listed companies in Tehran Stock Exchange. For this purpose, 140 companies were selected for the implementation of this research from 2012 to 2016. Combined data approach was used to test the research hypotheses. The results showed that financial constraint has a direct and significant effect on the risk of falling stock prices. That is, the constraint on financing is linked to stockpiling bad news and ultimately to falling stock prices. The sample companies were also divided into two groups of companies with strong and weak corporate governance, as well as those with and without tax avoidance. The hypothesis test results showed that the positive effect of financial restraint on the risk of falling stock prices is more severe in companies with poor corporate governance or tax avoidance. Finally, the findings show that the results are consistent with representation theory.

The purpose of the present study is to determine the impact of the trade credit financing on the risk of stock price crash risk by emphasizing the role of information asymmetry.

In order to achieve the research objectives, 141 companies is selected from the listed companies in Tehran Stock Exchange during 2008- 2017. Multiple regression model and panel data is used to test the research hypotheses using two criteria of stock price crash risk.

The results indicate that trade credit financing does not have a significant effect on the stock price crash risk. Also, information asymmetry cannot affect this relationship.

The results of the research suggest that suppliers can not prevent future stock price risk through regulatory and information mechanisms, in other words, suppliers can not prevent bad news from accumulating. In fact, Trade credit does not provide much of an advantage to the supplier, and the supplier cannot evaluate and monitor its customers.

Most of the research about the stock price crash risk has focused on the uncertainty of information, corporate governance, and operating activities and has not paid much attention to the impact of financing. In this study, the relationship between financing through trade credit  and the  risk of stock price crash  is discussed, Given the issues that may affect this relationship, an analysis and consideration of one of these factors, that is, the gap between the producer and the user and is known as information asymmetry, Paid.
