Several studies have examined the investor sentiment in the behavioral finance. But, most prior studies solely document the phenomenon that investor sentiment could affect stock price combined with accounting information and indicate the heterogeneity of the sentiment effect. However, the existing literature rarely provides a theoretical basis for the mechanism behind the effect of sentiment and the accounting information. Therefore, this paper the through theoretical basis effect of investor sentiment on the expected earnings growth rate analyzes the mechanism behind the effects of investor sentiment and accounting information on stock price based on the residual income valuation model. In order to reach this goal, the study has been carried out on a sample of 560 companies, during the 2009-2016 reporting period based on the Multivariate regression. The results show that higher sentiment leads to more optimistic expectations regarding future earnings growth and these optimistic expectations leads that investor sentiment changed the expected earnings growth rate, thus affecting the accounting information and stock price.

Estimating informative efficiency in financial market is crucial for investors. They can gain unusual profit when the market is inefficient. As informative efficiency is evolving and undergoing changes in emerging markets such as Iran, classic methods for efficiency estimation in these kind of financial markets are not suitable. Therefore, in such markets a hybrid method needs to be applied in such a way that the existing status of efficiency (static approach) and the efficiency during time (dynamic approach- in the absence of static efficiency) can be studied. The present study aims to determine the efficiency of Tehran Stock Exchange market by both static and dynamic approach. In order to obtain this goal, a combination of TVPGARCH and Kalman filter methods were applied on weekly total price index data during 2008 to 2017. Results indicate that the performance in Tehran Stock Exchange market in the static form does not have week efficiency. On the other hand, there is no evidence of efficiency dynamicity in Tehran Stock Exchange market performance during the studied period. Manuscript profile

The study of the probability of the occurrence of the extreme events (the events which occur with low probability of occurrence) is an important issue in the risk management. Extreme value theory calculates risk measures using extreme events for a financial basket, regardless of the distribution function of the return of the financial assets. In this theory, the method of peaks over threshold is practically the most appropriate and applied method by the use of which separate modeling of the tail part of the dataset is possible by using the generalized Pareto distribution and the start of the appropriate threshold. For this reason, in this paper, the methods of maximum likelihood estimator, likelihood moment estimator, Zhang and the weighted nonlinear least squares under the POT framework have studied and compared to estimate the parameters of the generalized Pareto distribution in order to estimate the value at risk and the expected shortfall of indices of food other than sugar, banks, car, chemicals, pharmaceuticals, cement, agriculture, petroleum products, textiles, coal, financial , industrial, the price of 50 companies, free float and the second market of Tehran stock exchange from March 25, 2013 to May 18, 2016. The overall results show that the expected shortfall is a more coherent measure for risk calculation, and the nonlinear weighted least squares estimator under the POT framework provides better estimation for generalized Pareto distribution.

The aim of this study is the examination of put option transactions volume increasing in Tehran Stock Exchange as result of increasing in stock returns and volatility of stock index. A put option is an option contract giving the owner the right, but not the obligation, to sell a specified amount of an underlying security at a specified price within a specified time. 32 companies which issued put option during the 1391 to 1394 have been selected as the study population were studied. Based on the findings and results of statistical analysis in case of desired and positive stock returns due to high investment risk, investors are more willing to trade put option. Therefore, despite the expected positive returns, Shareholders insure their equity investment against the risk. But if the volatility index was high, it means the risk would be high. In such a case, despite the high risk Shareholders do not tend to enter the market of put option. Manuscript profile

The present research tries to assess and compare the Capital Asset Pricing Models in stock exchange of Tehran. Financial data of 108 companies in stock market (2009-2014) are processed. The important issue is to use suitable patterns and models for evaluating and price setting in stock market. These models must have the ability to predict the behavior of the prices and also can estimate the outcome and efficiency of the so-called investment. The models investigated in this research, include the traditional investment financial pricing, 3-factor model and FAMA and French 5-factor and consumption investment models. In order to analyze the data and to test the hypothesis, we used OLS model for time series models. In this study, models are investigated according to the models of significance lateral distance from the source (Jensen's Alpha). A model, of which efficiency is high, should have a zero intercept. Generally, FAMA and French 5-factor models that were developed in 2014, work more efficiently. Then comes the Capital Asset Pricing Model Manuscript profile

Inferring and inducing among the relations for many of the phenomenas is common in most of sciences. Accordingly, econophysics experts are trying to fill the gap between microeconomics and macroeconomics to explain complex financial systems, using the statistical physics tools. Using a dynamic econometric model, the impact of exchange and gold markets shocks on the stock market is studied. The results show the more significant contribution of the foreign exchange market shocks than the gold market shocks on the fluctuations of stock market. Furthermore, this study forms an assumptive portfolio consisting of three assets including stock, exchange and gold and use random portfolio theory to analyze the risks and uncertainty. The level of uncertainty and risk is studied by using the characteristics of the Castaing, Gagne & Hopfinger distribution functions. The results indicate a high level of uncertainty and risk in the macroeconomic assets portfolio. In other words, the occurrence of financial crises in these markets is expected. Manuscript profile
