The jumps in stock volatility are found to be so active that this discredits many recently proposed stochastic … volatility models, including the classic affine model with compound Poisson jumps that is widely used in financial modeling and … practice. Additional empirical work presents strong evidence for many common jumps, or co-jumps, in both the stock price and …

We consider the hedging of options when the price of the underlying asset is always exposed to the possibility of jumps … hedge in the presence of jumps cannot be improved upon by increasing the rebalancing frequency. In contrast, the superior … empirical support for the existence of jumps of random size in the movement of the S&P 500 index. We also find that the …

This article analyzes the specifications of option pricing models based on time-changed Levy processes. We classify option pricing models based on (i) the structure of the jump component in the underlying return process, (ii) the source of stochastic volatility, and (iii) the specification of...
