We stress the importance of distinguishing between realised volatility and implied volatility, and find that implied volatilities are essential for assessing the volatility feedback effect. We also study the impact of news on returns and volatility. We introduce a concept of news based on the difference between implied and realised volatilities (the variance risk premium) and find that a positive variance risk premium has more impact on returns than a negative variance risk premium.
