Book Description
In the first chapter, my coauthor and I examine the information content of option and equity volumes when trade direction is unobserved. In a multimarket asymmetric information model, equity short-sale costs result in a negative relation between relative option volume and future firm value. In our empirical tests, firms in the lowest decile of the option to stock volume ratio (O/S) outperform the highest decile by 0.34% per week (19.3% annualized). Our model and empirics both indicate that O/S is a stronger signal when short-sale costs are high or option leverage is low. O/S also predicts future firm-specific earnings news, consistent with O/S reflecting private information. In the second chapter, I show that in many asset pricing models, the equity market's expected return is a time-invariant linear function of its conditional variance, which can be estimated from options markets. However, I show that when the relation between conditional means and variances is state-dependent, an observer requires the combined information in multiple variance horizons to distinguish among the states and thereby reveal the equity risk premium. Empirically, I show that while the VIX by itself has little predictive power for future S & P 500 returns, the VIX term structure predicts next-quarter S & P 500 returns with a 5.2% adjusted R-squared.

Book Description
This dissertation consists of three essays. The first essay tests whether stock returns can be predicted using divergence from put-call parity. Using a robust methodology that controls for the early exercise premium of American put and call options, the study shows that stocks with upside divergence from put-call parity outperform stocks with downside divergence from put-call parity. Predictability is persistent over multiple holding periods and divergence is also predictive of tail events. The second essay examines segmentation of equity and option markets in the presence of information asymmetry. The study uses the slope of the implied volatility skew as a proxy for negative jump risk, option implied stock price as a measure of deviation from put-call parity, and the daily short-sell volume ratio as a measure of negative information flow in the equity market. The option market based signals predict future returns more reliably than the short-sell based signals. Short-sellers only profit when their convictions line-up with negative signals in the option market. The third essay introduces a measure of fear derived from the implied volatility smile. The study examines the relationship between fear and the cross section of option returns. The results show that put options written on stocks with high fear premium outperform put options written on stocks with low fear premium. Fear does not predict the realization of a tail event. This finding confirms the irrational nature of fear.

Book Description
Do financial derivatives enhance or impede innovation? We aim to answer this question by examining the relationship between equity options markets and standard measures of firm innovation. Our baseline results show that firms with more options trading activity generate more patents and patent citations per dollar of R&D invested. We then investigate how more active options markets affect firms' innovation strategy. Our results suggest that firms with greater trading activity pursue a more creative, diverse and risky innovation strategy. We discuss potential underlying mechanisms and show that options appear to mitigate managerial career concerns that would induce managers to take actions that boost short-term performance measures. Finally, using several econometric specifications that try to account for the potential endogeneity of options trading, we argue that the positive effect of options trading on firm innovation is causal.

Book Description
These two essays demonstrate the important role that derivative markets play in assimilating information into financial markets. In the first essay I use the 2008 short-selling ban to examine the impact of single-stock futures (SSFs) trading on options market quality. I show that there is a substitution effect between options trading and SSFs trading during the ban period. In addition, my results show that SSFs trading had a significant effect in narrowing the bid-ask spreads of options contracts. Moreover, compared to stocks without SSFs, stocks with SSFs were less likely to violate put-call parity during the ban period. My results suggest that SSFs trading helps mitigate the negative effect of the short-selling ban on options market quality documented in the literature.In the second essay I look at information flows through large option trades. The motivation comes from CNBC's "Halftime Report" which regularly covers unusual option activity, i.e., those abnormally large trades, and recommend investors to follow the "smart money". I investigate the impact of the CNBC coverage on underlying stock prices and whether investors can indeed profit by following the "smart money". I document an immediate spike in trading volume and abnormal returns at the time of the CNBC coverage, and evidence that the unusual option trades are informative of stock prices around the coverage. However, I also document a significant reversal in underlying stock prices following the CNBC coverage. Using the same criteria advocated by the CNBC commentators, I identify unusual option activities for a large sample of stocks without CNBC coverage. I confirm that the unusual option trades significantly predict underlying stock returns, but find no evidence of reversal in underlying stock prices. My findings suggest that the CNBC coverage of unusual option activity has a destabilizing effect on underlying stock prices and investors cannot profit by simply following the CNBC reporting on the "smart money".

Book Description
This dissertation consists of three essays that explore the information content embedded in equity options. The results improve our understanding of the cross-section of option returns, informed trading in the options market, and the industry effect of IPOs. In the first essay, we study the relation between option-implied skewness (IS) and the crosssection of option returns under daily hedging to better understand skewness pricing in isolation from lower moments. Creating portfolios of delta-hedged (D-hedged) and delta-vega-hedged (DV-hedged) options with daily rebalancing, we find that IS is negatively (positively) related to call (put) option returns, but the relation to put options is statistically significant only during economic recessions. The relation is more substantial when the underlying stock has a larger market beta and when the firm has more severe information opacity. Our results suggest that investors' skewness preference grows stronger with greater market risk and lower information quality. In the second essay, we examined the informed trading in the options market before FDA drug advisory committee meetings. We find significant abnormal options trading volume before both meeting dates and report creation dates, particularly for small drug firms. Abnormal volume significantly predicts post-meeting stock returns. Informed traders prefer out-of-the-money options and choose maturities to cover the dates when reports are publicly released. They prefer to sell options close to the meeting date, perhaps to capture returns from both expected stock price changes and the sharp drop in implied volatility post-meeting. In the third essay, I investigate the effect of initial public offerings (IPOs) on industry competitors' options market. I find that rival firms' put (call) options volume increases (decreases) around IPOs, leading to price pressure on call options relative to put options as measured by the implied volatility spread. Rival firms' reaction in the options market also predicts the IPO firms' post-IPO stock performance. Lastly, rival firms with strong operating income experience less negative impact in the options market, suggesting competitive operation performance help stabilize rival firms' options market around IPOs.

Book Description
How do option and equity markets interact with each other? This is the central question that is answered from three different angles in this dissertation. The first Chapter discusses how option-implied information is incorporated into equity markets. Based on a novel rescaled option-implied Value-at-Risk (rVaR) measure, it is shown that option-implied information is priced differently depending on whether it is based on options with strikes close to the current price of the underlying or far-out-of-the-money options. The findings provide novel insights in the joint interaction between option and equity markets and help to explain contradictory results in previous studies. The second chapter provides an in-depth analysis of how to estimate risk-neutral moments robustly. A simulation and an empirical study show that estimating risk-neutral moments presents a trade-off between (1) the bias of estimates caused by a limited strike price domain and (2) the variance of estimates induced by micro-structural noise. The best trade-off is offered by option-implied quantile moments estimated from a volatility surface interpolated with a local-linear kernel regression and extrapolated linearly. The third chapter expands volatility targeting to option strategies. The chapter shows that option trading strategies can be managed by increasing exposure if volatility is low and reducing exposure if volatility is high to achieve a constant risk exposure over time. These volatility controlled option strategies generate economically and statistically significant alphas over their unmanaged counterparts, have reduced maximum drawdowns, lower downside risk, and more normal return distributions.
