The option implied volatility spread and skew predict stock returns. These variables also reflect the expected cost of borrowing stock to sell short. The stock borrowing fee implied from options prices predicts changes in quoted borrowing fees and stock returns; however, the volatility spread...

Property-casualty (P&C) insurers are exposed to rare but severe natural disasters. This paper analyzes the relation between catastrophe risk and the implied volatility smile of insurance stock options. We find that the slope is significantly steeper compared to non-financials and other financial...

Since the collapse of the Metallgesellschaft AG due to hedging losses in 1993, energy practitioners have been concerned with the ability to hedge long-dated linear and non-linear oil liabilities with short-dated futures and options. This paper identifies a model-free non-parametric approach to...

We study implications of asymmetries in both preferences and fundamentals for put option demand across investors and the resulting market behavior. A heterogenous-agent model populated by investors with asymmetric preferences alongside standard risk-averse agents rationalizes the size and the...

In this paper, we propose a methodology for measuring information flows underpinning option price movements, and for analyzing the distribution of these flows. We develop a framework in which flows of information can be measured in terms of relative entropy between risk-neutral distributions...

The paper shows how the traditional credit model based on contingent claims analysis can be adjusted when the capital structure includes a short position in a call or put option. The stochastic features of the asset underlying the option introduce additional risk elements into the analysis of...

The monthly trading volume and proportion of Zero-Day-to-Expiry (0DTE) options have increased from zero to 26 million contracts and from zero to 40% between 2011 and 2022. We study how 0DTE option trading affects the volatility of the underlying asset. We find that more 0DTE options trading...
