You can apply the std calculations to the resulting object: If you don't plan on using the rolling window object again, you can write a one-liner: Keep in mind that ddof=0 is necessary in this case because the normalization of the standard deviation is by len(Ser)-ddof, and that ddof defaults to 1 in pandas. The empirical results show that: (1) Both the idiosyncratic volatility and jump risk should be independently priced; (2) When added the idiosyncratic volatility into jump risk-return model, the jump measurement components have less explanatory power for stock premium, indicating these two risk factors that contains common information for the stock premium; (3) The explanatory effects of idiosyncratic volatility and jump risk on return mainly origins from the non-linear form of their interaction, which provides empirical experience for theoretical analysis of the specific forms of risk.
