Recent developments allow a nonparametric separation of the continuous sample path component and the jump component of realized volatility. We add implied volatility from option prices to this analysis. We show that implied volatility has incremental information relative to both the continuous and jump components of realized volatility, subsuming the information content of both in most of our specifications, when forecasting subsequently realized return volatility. Furthermore, implied volatility has predictive power for future values of both components of realized volatility, consistent with the notions that option markets aggregate information efficiently, and that even the jump component of realized volatility is, to some extent, predictable.
