The objective of the study is to know the breaks at the specified breakpoints (Covid-19 Announcement). This paper applied the CUSUM of Squares test, chow breakpoint test, and F-Statistics on daily basis the event window (?30days, Event date,?+30days) of seven emerging and sustainable indices of the world namely, viz, China, India, Brazil, Mexico, Russia, Indonesia, and Turkey. The interpretation of the graph of the series indicates that breakpoint. The findings of simple regression are significant. The stability diagnostic of CUSUM Square test degradation shown out 5% level of significance, meaning the break in the model. In the Chow test, the null hypothesis is rejected, there is a break as on covid-19 date of announcement breakpoints, the value of f-statistic is significant at 5% level. It is life-threatening to consider the change due to the Covid-19 in selected sustainable indices. Our estimation allowed counterfactual experiment to indicate that the covid-19 affected the stock market deviation on the announcement of Nobel coronavirus in the world.
