In recent years, a liquid market for options on a broad credit default swap index (CDX) has developed. We study the extent to which these options are priced consistently with options on a broad equity index (SPX). We consider a rich structural credit risk model in which firm assets follow a...

We examine whether the dynamics of the implied volatility surface of individual equity options contains exploitable predictability patterns. Predictability in implied volatilities is expected due to the learning behavior of agents in option markets. In particular, we explore the possibility that...

This paper describes an empirical study of the information content of daily share prices and American put and call option mid-quotes about their generating process. Considering stock return and its volatility as the risk factors and without parameterizing their historical joint dynamics, two...

This paper explores the contagious propagation of jumps among international stock market indices by exploiting a rich panel of stock and options data. We propose a multivariate option pricing model designed to allow for, but not superimpose, time and space amplification of jumps in option...

We find that informed trading in the option market prior to dividend initiation is negatively related to announcement period price reactions. This relation is more prevalent among firms with abnormal trading in call options, higher stock price runup, and higher option liquidity. We also find...

We formally compare two versions of the market Variance Risk Premium (VRP) measured in the equity and option markets. Both VRPs follow common patterns and respond similarly to changes in volatility and economic conditions. However, we reject the null hypothesis that they are identical and find...

We examine stock return predictability of "Out-of-The-Money (OTM) put-to-OTM call trading volume ratio" (OTMPC). Our numerical analysis predicts that informed investors hardly write OTM options because the leverage effect is not sufficient to compensate for transaction costs. OTMPC, thus,...
