Given the inherent complexity of financial markets, a wide area of research in the field of mathematical finance is devoted to develop accurate models for the pricing of contingent claims. Focusing on the stochastic volatility approach (i.e. we assume to describe asset volatility as an...

This paper proposes a new reduced-form model for the pricing of VIX derivatives that includes an independent stochastic jump intensity factor and co-jumps in the level and variance of VIX, while allowing the mean of VIX variance to be time-varying. I t the model to daily prices of futures and...

The rapid growth of exchange traded products (ETPs) has raised concerns about their implications for financial stability. A case in point is the abrupt market crash of short volatility strategies on February 5th 2018. In this paper, we describe this “Volmageddon” event and illustrate the...

This paper presents a joint analysis of the term structure of credit default swap (CDS) spreads and the implied volatility surface. The rapid development of the CDS market has provided convenient products to extract credit risk, and its interaction with equity volatility has been analyzed in...

In this paper, we consider hedging and pricing of illiquid options on an untradable underlying asset, where an alternative instrument is used as a hedging instrument. We assume that the trade price of the hedging instrument is subject to market impacts caused by the hedger, as well as the...

In this paper, we promote the approach of relative indifference pricing as a conceptual enhancement of real options theory whenever incompleteness comes into play. As until now the discussion of this concept is limited to the field of mathematical finance, our goal is to stimulate its diffusion...

This paper examines the joint time series of the S&P500 index and its options with a two-factor Hawkes jump-diffusion model that captures jump propagation (i.e., the phenomenon in which the strike of one jump substantially raises the probability for more to follow). The propagation effect...

I investigate the relation between option prices and daily stock return serial correlation. I demonstrate that the variance ratio, calculated as the ratio of realized to implied stock return variance, has both a contemporaneous and predictive relation with stock return serial correlation. The...

We examine whether option prices correct for predictable bias in stock prices associated with accounting anomalies. Evidence from put-call parity violations suggests that they do not. Rather, option prices accurately track contemporaneous stock prices. Further analysis suggests that high costs...
