Financial market volatility is an important indicator for measuring risk in the market, which has an important impact on investors' decision to measure risk, manage investment portfolios, and pricing, and is a common concern of government regulators, investors, and capital markets. Mean-variance trade-off in periods of strong financial market volatility, there is a negative correlation between stock returns and changes in volatility, because expected returns are related to the conditional variance of returns in periods of weak volatility. The aim of this research is to present a model based on the effect of the financial market volatility regulator and the average variance relationship of stock returns. The statistical population of this research consists of the companies accepted in the Tehran Stock Exchange, based on the systematic elimination method, the number of 112 companies during the years 1394-1400 was selected as the sample size. The method of collecting information is library and field. The data analysis was done using the multivariable regression model provided in the research with the help of Stata software. The results of the research hypothesis test showed that financial market fluctuations have a significant relationship with the average variance of stock returns. The amount of total volatility has also had a positive effect on the average unpredicted variance of stock returns, which shows that the stock price is the focus of investors on the stock market and has reduced investment risk and adverse shocks in the stock market, increasing the volume of stock return transactions. Also, the rate variables have increased. Currency, inflation, real output growth has been able to increase the mean variance of stock returns.

The capital market is considered as one of the most important markets in the economy of each country due to the accumulation of small funds for implementation of large investment projects. The purpose of this research is analyzing the impact of the monetary and fiscal policies on Iran's capital market in the Construction, Reform, Justice and Hope in a long-term of  25-year period. The number of observations of this research was 100 observations. In this research, the most important capital market indices were included total index and number the of companies accepted in Tehran Stock Exchange as a dependent variable and in the sector of monetary and financial policies the monetary and financial variables were converted from nominal to real by using the general index of prices in all observations. In this research, out of 360 models, 2 final models were extracted and analyzed. In analyzing the data to determine the effect of the independent variable on the dependent variable multiple Regression was used, as well as to compare the different governments the Wald test was used and to test the root of the Dickey Fuller test, that means the total stock index is different in the governments of Iran, and there is no significant difference between the variables of the number of companies
