Based on the findings and results of statistical analysis in case of desired and positive stock returns due to high investment risk, investors are more willing to trade put option. Therefore, despite the expected positive returns, Shareholders insure their equity investment against the risk. But if the volatility index was high, it means the risk would be high.
