Abstract: 

One of the most important tasks of the financial economy is modeling and forecasting of the price volatility of risky assets. For analysts and policymakers, price volatility is a key variable that helps to understand market fluctuations. Therefore, the analysts need to be able to predict the correctness of price volatility as an essential input for tasks such as risk management, portfolio assignment, value at risk and transaction option pricing and future contracts. Accordingly, in the present research, return on stocks of Tehran Stock Exchange has been dealt with using PLS and TVP-SV models and its comparison with OLS method in MATLAB and XLSTAT software from March 2003 till August 2013 (monthly) using true variables (industrial output, real estate investment in housing, economic growth, government spending share in GDP and Non-oil exports growth rate) and monetary variables (inflation, money supply, exchange rate, oil price and domestic price of gold). Based on PLS model, the result was that the variables of economic growth and oil price have more influence of return of Tehran Stock Exchange in comparison with other variables. Then, we entered the variables of economic growth and oil price in TVP-SV model. Based on the results, TVP-SV model has more efficiency in comparison with OLS model. Based on the results of TVP-SV model after the first interruption of stock returns, the economic growth has the highest effect on stock returns.

Abstract: 

The information content of high frequency data has made them the main instruments for studying market microstructure. However, the noise content of this data may negatively affect the results of studies on market microstructure. Using maximum likelihood methodology, we disentangle from high frequency observations on the transaction prices of a sample of Tehran Stock Exchange stocks a fundamental component and a microstructure noise component. We then relate these statistical measurements of market microstructure noise to different financial measures of their market depth. We find that stocks with higher market depth have higher noise measured from their high frequency returns. This is in accordance with Fischer Black’s hypothesis that the existence of noise traders and the noise, which can be caused by the activities of this group of traders, to be the vital condition of a liquid market. We also find that pre-trade depth measures are the most powerful depth measure in explaining the noise in the market.

Abstract: 

In this article utility of investors contains utility from consumption and utility from fluctuations in their investments. To prove the effect of prior performance of investors on stock price first the utility function was defined based on Prospect theory and variables relating to prior outcomes and loss aversion were factored into utility function and then price equations were defined. In the other form, variables relating to prior performance in utility function were removed and price equations were defined. Next, the P/D ratio and logarithmic growth of stock prices were simulated in both forms and compared against real market data. By utilizing ANOVA and K-Means in the 1381-1393 period, it became clear that the mean and standard deviation in the first form are closer to real market data than those of the second form, meaning that removing variables relating to investors' prior returns from the utility function resulted in weaker estimates, the effect of prior investment performance of investors was confirmed.

Abstract: 

This study examines the Impact of investment firms ownership on management opportunistic behaviors in earnings overstatement, using the theoretical foundations of strategic alignment hypothesis, in a sample of 96, listed firms in Tehran stock exchange for a period of 8 years, from 2006 to 2013 that were simple random sampling selected. Data and theoretical foundations collected through library studies and analyzed using correlation method and multiple regression. The study results suggest that there is a significant and positive relationship between earnings overstatement and investment firms ownership. In other words, investment firms as a major shareholder, want to get the benefit of their investee firms. Investee firms managers maximize earnings for responding to its major shareholder too. This is approved in line with the strategic alignment hypothesis. The results also show that earnings overstatement have a significant and positive relationship with the variables of firm size, return on asset ratio and debt ratio. But there is a significant and negative relationship about operating cash flow.

Abstract: 

One of the most important applications of futures, hedging is that this application is also evident in the futures coins and various stakeholders can use it. In this paper, using time series dollar in free market and price of futures contracts coin during the period 1390 to 1393 to assess the risk of cross hedging exchange rate using futures contracts coin. First, the correlation between the exchange rate and price time series econometric model for future Coin vector regression (VAR) found. After the confirmation of residual autocorrelation and heteroscedasticity conditional on the VAR, the model BEEK (which is a multivariate GARCH model), conditional variance Currency and coins was estimated future prices and then by minimum variance hedge ratio was calculated for different maturities and the profit or loss resulting from currency risk hedging gain or loss resulting from exchange rate fluctuations were real. The results show that there is a high correlation with the price of the coin exchange rate (US Dollar), possibility of covering cross-currency risk using futures contracts provide for gold coins. Also, due to long-term memory between exchange rate fluctuations and price estimation of future coins hedge ratio through BEEK-GARCH model, and using this model include more than 70 percent to compensate losses from currency risk.

In this study, using insights of CAPM and three-factor model (Fama and French, 1993), PEG and four-factor models was developed. Using financial data of 270 companies traded in TSE during the beginning of 2006 to the end of 2014, three-stage methodology and the portfolio study methodology used to calculate the risk factor. The results show that first, there are inverse size effects, inverse value effects and PEG effects, second, PEG model cannot explain stock risk premium, But the four-factor model compared with other models, has higher power for explaining of the risk premium. Market participants can use these results to improve investment performance and academics recommended that test models of the study.

Abstract: 

Intangible information, which is often obtained from the unofficial sources, causes information asymmetry in the capital market. This information will primarily create advantages for some investors; however, over time, with the release of intangible information and turning it from underhand information to revealed information, the value and power of this information advantage will be reduced. On the other hand, in decision making model for herding behavior, unconditional compliance of other investors, because of assuming that they have an informational advantage, is the basis for decisions. These decisions lead to the influx of investors to trade the stock and fluctuation in prices that causes inefficiency, instability and fragility of the market. In this study, the effect of intangible information on herding behavior of institutional investors has been studied in Tehran Stock Exchange during 2010 to 2014. In this regard, by comparing the results of Christie and Huang model and also Lakonishok, Shleifer and Vishny model, the effect of intangible information on herding behavior of institutional investors was analyzed. The results indicate that, confirming the impact of intangible information on herding behavior of institutional investors, the impact is more intense on the Christie and Huang model compared to the Lakonishok, Shleifer and Vishny model.

Abstract: 

In the present study a batch of questionnaires was handed out to a group of stock market investors in Tehran addressing the question: “Why individual investors yearn for dividends? ” The data was gathered later on and the results revealed that this inclination on getting the dividends is, to a certain extent that the cost of cashing dividends turns out to be a lot lower than that of selling shares. The results are, on one hand, strongly confirming and corroborating the “Signaling Model” of Bhattacharya (Imperfect information, dividend policy and the bird in the hand) and of Miller and Rock (Dividend policy, growth and the valuation of shares), and yet on the other hand, opposing the “Agency Theory” of Jensen. Furthermore, it is drawn from the results that the “Behavioral Finance Theory” of Shefrin and Statman for cash dividends is not confirmed. In conclusion, the findings of the study are indicative of the fact that individual investors have no tendency on spending a large part of their dividends.

Abstract: 

Trying to identify an appropriate model to enhance measurement accuracy by using value at risk measures is of particular importance. Conditional Value at Risk (CVaR) with having some of the shortcomings of VaR, is a more reliable measure. In this study, the characteristics of the Tehran Stock Exchange index data usage FIGARCH-EVT model to calculate value at risk if states have been more accurate. GARCH-EVT hybrid implementation model and its development, FIGARCH-EVT model, we found that the effect of clustering, dynamic and long-term memory has been included in the modeling. FIGARCH model for log data output index, which will be modeled in terms of the above properties. In addition, the wide trail property index return data using extreme value theory (EVT) is used for residual FIGARCH model. To compare the results, NORMAL-GARCH models and t-Student-GARCH, historical simulation and GARCH-EVT indicator is used for data output. The results of the model using retrospective tests were evaluated. The results of this study indicate that the data distribution is skewed and asymmetrical index returns do not follow a normal distribution. The tests Standardized Exceedance Residuals and The Cumulative Violation Process and Expected shortfall backtesting and loss function Lopez FIGARCH-EVT model over other models is more accurate.
