The growth of oil prices has had a negative and significant effect on all stock market index regimes. Also, in the high regime of the stock market index, the prevalence and increase in the coronavirus cases will lead to a decrease in the stock market index, and on the contrary, in the low regime of the stock market index, the prevalence and increase in the coronavirus cases will increase the stock market index.
