The study also checked for the normality, Autocorrelation and Heteroscedasticity for the select data. For the purpose of the study daily returns are considered of Nifty 50 and returns of five randomly selected banks listed on Nifty 50. The present study also shows if there exists any significant impact of these bank stock returns on the Nifty 50 returns. All these stock returns are converted into log form for normality purpose.
