We nest multiple volatility components, fat tails and a U-shaped pricing kernel in a single option model and compare their contribution to describing returns and option data. All three features lead to statistically significant model improvements. A second volatility factor is economically most important and improves option fit by 18% on average. A U-shaped pricing kernel improves the option fit by 17% on average, and more so for two-factor models. Fat tails improve option fit by just over 3% on average, and more so when a U-shaped pricing kernel is applied. Our results suggest that the three features we investigate are complements rather than substitutes.
