The present research paper bondage of Indian stock market and other global empirically examines randomness and long term equilibrium stockmarkets, especiallyMIST county stock markets are a affiliation amongst the emerging stock market of India and vital one, because it will provide considerable motivation Mexico, Indonesia, South Korea and Turkey from the monthly time series data during February 2008 to October 2019. The for the Indian investors to look for the new investment researcher employs by the way, Run test, Pearson’s correlation opening across the globe for diversifying their portfolio for test, Johnsen’s multivariate cointegration test, VECM and getting higher returns. For understating of the volatility Granger causality test with reference to post-September 2008 estimation and forecasting, GARCH, EGARCH and Global financial crisis. The test results of the above finds that TARCH models are employed to estimate time-varying Nifty 50 and BSE Sensex is significantly cointegrated either correlation and leverage effects.In addition, the evidence of among themselves or with MIST countries particularly during cointegration and causality will enable to estimate long term the post-September Global financial crisis. No random walk is parameters or equilibrium with unit root variables and to found during the study period. The ADF (Augmented Dickey- check the direction of causality.

Leverage effect was randomness and volatility. apparent during the study period. So the influx of bad news has a bigger shock or blow on the conditional variance than the influx II. THEORETICAL FRAMEWORK OF THE STUDY of good news. The residual diagnostic test (Correlogram-Squared residuals test, ARCH LM test and Jarque-Bera test) confirms A number of studies reviewed the previous literature to GARCH (1,1) as the best suited model for estimating volatility know how the proposed research is related to prior research andforecasting stock market index. and identify new ways to interpret prior research. It permits Key terms: equilibrium, leverage effects, volatility clustering, us to detect volatility and comovement amongstock markets asymmetric effect, cointegration, causality, random walk, wherever cointegration occurs and when if the stock market persistence rise with big swings in either direction.
