Volatility is … inherently latent, and Section 1 begins with a brief intuitive account of various key volatility concepts. Section 2 then …

A rapidly growing literature has documented important improvements in volatility measurement and forecasting … provides a practical framework for non-parametrically measuring the jump component in realized volatility measurements … an easy-to-implement reduced form model for realized volatility results in highly significant jump coefficient estimates …

This study reconsiders the role of jumps for volatility forecasting by showing that jumps have a positive and mostly … significant impact on future volatility. This result becomes apparent once volatility is separated into its continuous and … yields) shows that the proposed techniques improve significantly the accuracy of volatility forecasts especially in periods …
