Using leverage adjusted index option data, a novel prediction of the anchoring adjusted option pricing model is tested. The anchoring model is based on the idea that the risk of the underlying stock is used as a starting point that gets adjusted upwards to estimate call option risk. The...

We analyze the effect of option trading on the return predictability of short interest. There is no difference in the return predictability of short-interest ratios between stocks with and without traded options. The predictability of the put-call open interest ratio (PCOIR) is weaker than that...

Are options on more volatile assets expected to provide higher or lower return? Using analytics, we show the ambiguous nature of the answer when the volatility differential is due to the systematic/priced risk. Here the difference in the expected return of the assets also matters and has an...

In this paper, we explore the relation between information uncertainty and S&P 500 index option returns. Since underlying state variable affecting economy is unobservable, investors have to obtain their own estimations based on available information. During such procedure, it is inevitable that...

In literature, many researchers focus on information contained in stochastic volatility dynamics, such as CBOE VIX index and its risk premium. However, there are relatively fewer studies on stochastic skewness dynamics. Simple linear regression indicates that stochastic volatility and stochastic...

An anchoring-adjusted option pricing model is developed in which the volatility of the underlying stock return is used as a starting point that gets adjusted upwards to form expectations about call option volatility. I show that the anchoring price lies within the bounds implied by risk-averse...

Constantinides et al (2013) put forward a number of empirical findings regarding leverage adjusted S&P 500 index option returns. Their findings are puzzling in the context of the Black-Scholes-Merton Option Pricing Model and the Capital Asset Pricing Model. Experimental evidence as well as the...

I show that the inventory risk faced by market-makers has a first-order effect on option prices. I introduce a simple approach that decomposes the price impact of trades into inventory risk and asymmetric information components. While both components are large for option trades, the inventory...

Prior research documents that volatility spreads predict stock returns. If the trading activity of informed investors is an important driver of volatility spreads, then the predictability of stock returns should be more pronounced during major information events. This paper investigates whether...

Speculators who wish to bet on higher future volatility often purchase options to “go long volatility.” Should investors who buy options expect to profit when realized volatility increases? If so, under what conditions? To answer these questions, we conduct an analysis of the relationship...
