We use the informational content of VIX derivatives to infer implications on the non-affine modeling of the stock returns' variance dynamics. We find that both a non-affine diffusion and variance jumps are necessary to capture the short- and long-term implied volatility distribution. In- and...

We analyze pricing models for VIX derivatives which account for the theoretical link to stock options, taking Log-VIX models as a benchmark. We focus on up to three risk factors to model variance risk. To assess the performance of the models, we do not only look at the pricing errors, but also...

This paper studies the volatility-of-volatility (VVIX) term structure. We find that the slope of the VVIX, defined as VVIX' second principal component, predicts excess returns of S&P500 and VIX traddles. Its informational content is incremental to the VIX term structure and the variance risk...
