Recent work considers whether information is simultaneously reflected in both option and equity markets. We provide new evidence supporting Black's (Financ. Anal. J. 31:36–72, 1975) conjecture that information is first revealed in option markets. Specifically, changes in call and put...

We dissect the impact of information contained for future asset returns in the implied volatility skew. Future returns are linked to the discrepancy between call and put volatilities of at-the-money options and to the left side of the volatility skew, calculated as the difference between...

This paper examines the information content in option prices and volatility surrounding analyst recommendation changes. The sample includes 7,549 recommendation changes of optionable stocks over the period January 1996 to December 2005. As expected, mean underlying asset returns are positive on...

Recent work has considered whether information is simultaneously reflected in both option and equity markets. We provide new evidence supporting Black's (1975) conjecture that information is first revealed in option markets. Specifically, changes in call and put open interest levels have...

This study investigates if changes in risk-neutral systematic volatility, skewness, and kurtosis, are priced, either symmetrically or asymmetrically, as systematic risk factors in the cross-section of stock returns. The moments are constructed using options on the S&P 500, and represent...

Using the risk-neutral volatility and skewness computed from options on the S&P500, we show there is an asymmetric contemporaneous relation between stock returns and changes in implied market volatility and skewness. Changes in expected market volatility and skewness are cross-sectionally priced...

Assuming a symmetric relation between returns and innovations in implied market volatility, Ang, Hodrick, Xing, and Zhang (2006) find that sensitivities to changes in implied market volatility have a cross-sectional effect on firm returns. Dennis, Mayhew, and Stivers (2006), however, find an...

While insurers manage underwriting risk with various methods including reinsurance, insurers increasingly manage asset risk with options, futures, and other derivatives. Previous research shows that buyers of portfolio insurance pay considerably for downside protection. We add to this literature...

Quarterly earnings conference calls are becoming a more pervasive tool for corporate disclosure. However, the extent to which the market embeds information contained in the tone (i.e. sentiment) of conference call wording is unknown. Using computer aided content analysis, we examine the...

Using computer based content analysis, we quantify the linguistic tone of quarterly earnings conference calls for publicly traded Real Estate Investment Trusts (REITs). After controlling for the earnings announcement, we examine the relation between conference call tone and the contemporaneous...
