AB This article examines whether incorporating jumps with stochastic volatility can improve the predictive power of option-implied densities of the FTSE 100 index. A general double-jump model is used to fit the market prices of options and to estimate “risk-neutral” densities. “Real-world” densities are then converted from their risk-neutral form by means of alternative statistical calibrations. Both the risk-neutral and real-world densities are evaluated over five forecast horizons using two different tests. The empirical results indicate that adding jumps into the price and/or volatility processes not only substantially lowers the fitting errors of option prices, but also improves the predictive power of risk-neutral densities. Furthermore, satisfactory density prediction was consistently provided by the real-world densities, which were not dependent on the addition of jumps, the approach used to construct the densities, or the prediction horizon.TOPICS: Options, volatility measures, VAR and use of alternative risk measures of trading risk
