This study survey and tests the underlying psychological mechanisms on how investors’ past perceived portfolio returns affect their trading and risk-taking, and is these psychological mechanisms are significant mediators. This study by use of structural equation modelling –partial least squares look into the relationship between past return and financial behavior and use psychological biases as a mediate variable. The statistical population of the present study is real investors who have come to Tehran Stock Exchange or close brokers in January and December of the year 2017. The research tool is a Likert Scale questionnaire distributed among investors. In this research, we use psychological biases as multiple mediators for first in Iran. The results lead to the conclusion that the presence of psychological biases plays as a full variable mediator in this study. The relationship between investor’s behavior and past return is indirect by a variable mediate called psychological biases.The results lead to the conclusion that the presence of underlying biases deteriorates financial behaviors

The interaction of managerial ownership and corporate performance in accordance with their endogenous nature is studied in this research. In other words, interrelations of mentioned variables along with some relevant variables of using three stage simultaneous equations and panel data are inquired. To do this, quasi-research method is used for 134 listed companies of Tehran Stock Exchange during period of 1380 to 1389. Results of testing research hypotheses indicate positive significant effectiveness of performance on managerial ownership. The most important factors of making managerial ownership which lead to better performance are considered as bonus shares of management bonus plan and information asymmetry problem. Moreover, results of research do not confirm performance effectiveness from managerial ownership. Thus, research findings do not verify this predicate that “due to coordination of management and tockholders’ interests increasing managerial ownership causes agency expenses decreases and increases in stockholders’ interests

In capital assets pricing model (CAPM) frame, the all effective factors in expected return, are summarized in Beta. As many assumptions in this model are not real, it necessitates the development of new models, and each one of them in its own part caused a new deficiency in mentioned assumptions. In CAPM the assumptions are based on the fact that distribution of returns is normal and all investors are risk averse. However, distribution of returns is not always normal and often there is a significant difference between normal distributions. Mean-variance can be the best method for decision making. If distribution of returns is not normal, then mean-variances generalization is not working. Existence of representative problems, valid or limited debts, correlation between volatility and pricing, and compound returns are factors lid to asymmetry in portfolio returns. As a result, this paper by using cross sectional data and based on Fama-Mac Beth model is analyzing the effect of higher moments on future stock return. In this paper, because of applied target as descriptive research there is a correlation which the effect of skewness and kurtosis of equity return distribution and nonsystematic volatility on future stock return is examined by three different hypothesis. In order to accomplish this paper, a sample of 76 firms participating in Tehran exchange stock between 1389 to 1393 as systematically elimination is selected. As a result of this research, skewness coefficient is effective on future stock return and has a negative relationship with it. On the other hand, whatever the skewness of distribution is negative, then the future stock return is going up. And also there is a positive effect between nonsystematic volatility of equity return and future’s return. On other word, investor by increasing nonsystematic volatility and accepting higher risks, expects higher return in the future

Issues and problems associated with financial statements have raised ambiguities about the role and responsibilities of the board of directors as well as the audit committee in financial reporting. Accounting restatements indicates that the financial statements of the past periods are unlikely to be presented in accordance with the generally accepted accounting principles. In addition, the Accounting Restatements may indicate weakness in the firm's internal control system. An efficient director labor market wills likely reward directors who have a reputation for effectiveness with additional board positions and associated benefits, and penalize the poor performers by loss of their positions and benefits. In the present study, the consequences of financial statements as a reporting failure for non-executive directors with an emphasis on the audit committee are examined. For this purpose, 43 listed firms were selected as the main sample and 43 listed firms as the control group during the years 2012 to 2016 from Tehran Stock Exchange. According to the results of the study, the financial restatements have not led to the imposition of labor market fines for outside director

Applying effective supply chains and planning the models of evaluating performance have been considered in recent years. The main purpose of this chain is reducing costs, increasing the effectiveness and efficacy and in general improving profit for all its stakeholders. The present study attempted to investigate the possible effect of Financial Supply Chain Management (FSCM) on performance of companies that listed in Tehran Stock Exchange. For this purpose, the 3 month interim (seasonal) data of 37 pharmaceutical and cement companies (888 seasons - company) during 2009-2014 were utilized as sample. The results showed that there was a meaningful negative effect of Days of Sales Outstanding, Days of Inventory, and Operating Cash Cycle on performance. Thus, firms’ managers could improve their performances by adopting plans and policies in the field of financial supply chain. However, there was not found any significant effect on Days of Payables Outstanding, Cash Conversion Cycle on firms’ performance

In this study, using a sample consisting of 2702 firm-year observations of firms listed in Tehran Stock Exchange, which their data were obtained for a period of 11 years from 1382 to 1392, we investigate whether firms with small pre-managed negative earnings, manage their income through real earnings manipulation to avoid losses or not. The implication of behavioral studies suggests zero earnings threshold might function as an important psychological reference for which managers have strong incentive to beat or exceed it and they are likely to engage in activities like offering customers price discounts to temporally increase sales, overproduction to lower cost of goods sold and decreasing discretionary expenditures to improve earnings reported to stakeholders. Our initial findings documented a significant discontinuity and irregularity in the pooled cross-sectional empirical distributions of earnings scaled by the total assets in intervals close to zero. Despite the evidence was consistent with earnings management explanation, other statistical findings did not provide evidence and support the prediction that managers boosted their income through activities like unusual sales discounts, overproduction, and cutting discretionary expenses to meet the earnings threshold
