The goal of this paper is to introduce a new model to predict the high volatility of Tehran Stock Exchange. For do it, a Markov switching GARCH models was modeled. With Estimating this model, the transition probability matrix of two states of high and low volatility, was calculated. Using this matrix, we can forecast the probability of market fluctuations in the each period ahead and we can obtain a suitable model for forecasting high volatility. According to the model selection criteria consist of AIC and BIC, the Markov regime switching GARCH model with GED distribution is the best model for forecasting volatility in Tehran Stock Exchange. Based on this model, in this paper, an Early Warning System has been introduced in Tehran Stock Exchange.

Valuation is a knowledge which helps modeling all effective factors in the company's cash flow, while helping the share holders to determine stock intrinsic value, through discounting company's cash flow. One objective of a valuation system is to help students simulate changes in a firm’s financial strategies and discover how these changes affect a firm’s credit health or its value. It also simulates all company's financial affairs, through which the investors could calculate the relative reports on stock intrinsic value efficiency and regulate their transactions, as regards to the expected profit.Moreover, the Managers could also measure their decisions efficiency before the operations and render the highest return (value) to the stockholders.This research is a study over the efficiency of applying deferent approaches of valuation in obtaining the acceptable stock intrinsic value of private banks in Tehran securities exchange. Tentative instances show that discounted operating cash flow model has the most correlation coefficient with actual price of stock. Manuscript profile

In this study, Quadratic Discriminant Analysis (QDF) model and the hybrid model of Genetic Algorithm based on Artificial Neural Network)ANN-GA) are used to estimate manipulation of stock prices in Tehran Stock Exchange. In this study, first by using screening data method, a sample of 345 companies listed in Tehran Stock Exchange were selected and then information about the 'TEDPIX' index, closing price, volatility of closing price and trading volume in the timeframe years 1387 to 1391 were collected. Afterwards the selected companies categorized into manipulated and non-manipulated groups by using duration dependence test and run test. Then with scrutiny of the trend of Tedpix's chart and volume chart of the manipulated group, Start of price manipulation is determined. In next step by using Linear Discriminant Function)LDF) ,Quadratic Discriminant Function)QDF) and Genetic Algorithm based Artificial Neural Network and by using closing price, volatility of closing price and trading volume variables and also using information in range one year before starting manipulation group and in range four years for non-manipulation group, designed models for forecasting manipulation. At the end, the prediction ability of the models was examined. According to the results, the prediction ability of QDF model compared to the ANN model is better. Manuscript profile
