We consider a tractable affine stochastic volatility model that generalizes the seminal Heston (1993) model by … variance, and we examine the impact of the distribution of jumps on the associated implied volatility smile. We provide … sufficient conditions for the asymptotic behavior of the implied volatility of variance for small and large strikes. In …

This paper examines the cross section of options implied volatility and corporate bond returns. We document a strong … predictive ability of corporate bond returns using changes in call and put options implied volatility.

Speculators who wish to bet on higher future volatility often purchase options to “go long volatility.” Should … investors who buy options expect to profit when realized volatility increases? If so, under what conditions? To answer these … questions, we conduct an analysis of the relationship between long volatility performance (buying options) and contemporaneous …
