This paper investigates the information content of the risk-neutral skewness derived from S&P 500 index option prices for forecasting future volatility. Empirical results show that the risk-neutral skewness provides incremental explanatory power for future volatility. Moreover, the models with the risk-neutral skewness dominate in terms of out-of-sample forecasting performance, especially during the 2007-2008 financial crisis.
