The importance of predicting the price of energy carriers for the development of the economy and industry today is not overlooked. Meanwhile, predicting natural gas prices as one of the most important carriers of energy and an important role in providing clean energy can be considered as an important tool in industrial development decision making. In this paper, we have investigated the nonlinear behavior of natural gas prices in a multi-year period, as well we have introduced methods for the development and synthesis of fractalization (FDGM) has been used to predict the price of natural gas. The results of the price forecast based on the introduced methods, Indicates the effectiveness of these methods. At the same time, given the fractal nature of the price of natural gas in the period under review, the results show that the forecast error using the FDGM method is always below 7%. And very good results were obtained using combination fractional and fractional methods. Manuscript profile

The effect of information disclosure procedures and policies on the cost of equity capital is one of the important issues which always is considered by regulators, entities and financial and accounting researchers. This relation is affected by various contextual characteristics (e.g. ownership structures, legislating system, economy and so on). The aim of this research is to examine the effect of ownership dispersion on the relation between voluntary disclosure and cost of equity capital. In doing so, the number of 610 firms of TSE listed Company were selected via systematic screening method. Data for variables were collected from several databases, such as CODAL, Central Bank, TSE-Client 2 software, and Statistical Centre of Iran. These data were analysed by the regressions model. The evidence shows that voluntary disclosure, ownership dispersion, and their interaction have significantly negative relations with the cost of equity capital. These findings indicate that an increase in voluntary disclosure and ownership dispersion causes a decrease in cost of equity capital. In addition, ownership structure intensifies the negative effect of voluntary disclosure on the cost of equity capital. Manuscript profile

This study is examines the effect of default risk on explanatory power of Fama-French five factor model from 2009 to 2017 in Tehran Stock Exchange. In this regard, time series regression and GRS tests were used. For reaching the research purpose, Fama-French five factor model results compared with six factor model results, which default risk regarded as sixth variable using GRS test. In addition, for investigating the effect of default risk on return, time series regression was used. The research results showed that default risk variable has not a significant effect on the explanatory power of the Fama-French five factor model. In other words, default risk factor is not significant in explaining return change. Also, the results showed that among 36 investigated portfolios in this research, in most portfolios there is a positive relationship between default risk and portfolio’s return but only in 8 portfolios this relationship was significant.

The purpose of this study is to find an appropriate answer to the question of whether the abnormal accruals have an impact on the financing activities of companies accepted to the Tehran Stock Exchange or not? For this purpose, the financial information of 105 active companies in the Tehran Stock Exchange for the period of 6 years 2011- 2016 was tested using a combined analytical. In order to investigate the purpose of the research, three main hypotheses were presented separately using multiple regression models. Based on the analysis of the first hypothesis, it was found that anomalies of accruals have a negative and significant relation with the future profitability of the companies under study. The result of the second hypothesis is that there is no significant relationship between accrual accounting anomalies and adjusted returns at error level less than 5%. In the third hypothesis it was stated that anomalies of accruals have a positive and significant correlation with the cash flow from financing activities. These findings indicate the need for more attention from policy makers and market capitalists to the abnormal accruals. Manuscript profile

The aim of this study is to investigate the behavior of individual and institutional investors in Tehran Stock Exchange. For this purpose, we examined the portfolio statement of individual and institutional investors during a five-year period from 2012 to 2016. The result show that Investors’ behavior reflects some behavioral biases. Specifically, both individual and institutional investors tend to sell stocks that have appreciated in price, but not those that have depreciated in price (consistent with a disposition effect), although this tendency is more for individual investors. They also appear to believe that past returns are indicative of future returns (a representativeness bias), and their trading behavior shows that they are overconfidence. In the following, to investigate the effect of characteristics of investors on the cognitive errors, behavioral biases and trading error are investigated based on characteristics of investors.

Generally, the greatest risk in the capital market or in the portfolio of investors occurs when large sudden changes occur in the unfavorable portfolio. These losses are in the distribution sequence, and for this purpose they are called "limitative values". In this research, the logarithmic efficiency of the Tehran Stock Exchange Index based on the information received during the time interval between the day (due to the use of high frequency data) during the years 1392 to 1395, and the use of the maximum block approach in measuring the VaR value index is used. It turned out VaR index was calculated using historical simulation methods and variance-covariance method as the traditional risk assessment criteria and the results were compared. The results of data analysis in R software showed that the use of monthly information in calculating the risk-weighted value index has a higher predictive accuracy and the error rate (test error) in this case is lower than traditional risk assessment methods.

The use of models based on stochastic differential equations has attracted the attention of financial researchers in recent years and one of the most famous models is the Brownian Geometric Motion model. The purpose of this study is to predict the Tehran Stock Exchange total index, one of the important economic indicators for investors, using the geometric Brownian motion model. For this purpose, the total index of Tehran Stock Exchange was investigated in the period from the beginning of 1380 to the end of 1395. Finally, the results showed that the model was able to predict the 1 day horizons with high accuracy. Also, by increasing the length of the prediction horizon, the accuracy of the predicted values by the model is reduced, and the GBM model's ability to simulate the total index value of the stock exchange decreases Nevertheless, the predicted values are still high accurate until the 90-day forecast horizon.
