Book Description
This dissertation contains three essays on empirical asset pricing. In the first essay, I study the relationship between idiosyncratic volatility and expected returns of risky assets. I find that when the true asset pricing model cannot be identified, the idiosyncratic volatility obtained from a misspecified model contains information regarding the hedge portfolio in Merton's (1973) ICAPM. Empirically, I find that from 1815 to 2018, a combination of equal-weighted idiosyncratic volatility (EWIV) and value-weighted idiosyncratic volatility (VWIV) can strongly forecast stock market returns over short- and long-term horizons. Furthermore, EWIV and VWIV jointly can explain the cross-section of average stock returns. I show that the combination of EWIV and VWIV is a proxy for the conditional covariance risk in the ICAPM. The deduction also provides new insights concerning the tail risk measure proposed by Kelly and Jiang (2014). The second essay is a joint work with Bing Han. We propose a new and robust predictor of stock market returns and real economic activities based on information from equity options. We aggregate the difference in implied volatilities of at-the-money call and put options across stocks and find that the aggregate implied volatility spread (IVS) is significantly and positively related to future stock market returns. We attribute the predictive power to common informed trading in equity options instead of time-varying risk premium. The third essay, coauthored with Yoontae Jeon and Raymond Kan, studies the expected option return under an extended Black-Scholes model that incorporates the presence of stock return autocorrelation. We show that expected returns of both call and put options are increasing functions of return autocorrelation coefficient of the underlying stock. We find strong empirical evidence from the cross-section of average returns of equity options to support this prediction. Average returns of calls and puts as well as straddle returns all show monotonically increasing relationship with the degree of underlying stock's return autocorrelation coefficient. We also examine how the information on stock return autocorrelation helps investors to improve the out-of-sample performance of their portfolios.

"This thesis comprises three essays in empirical asset pricing. My first essay entitled "Are stock and corporate bond markets integrated? A Big Data Approach" I document the existence a growing Factor Zoo of discovered characteristics and factors that predict the cross-section of corporate bond returns and generate a significant high minus low portfolio alpha. I determine a higher statistical benchmark, by accounting for those characteristics and factors that have been discovered in published and working papers and find that in cross-sectional regressions and portfolio sorts of over a hundred characteristics and factors, on average 2.4% predict the cross-section of corporate bond returns when adjusting for higher benchmarks. A multivariate horse-race of all characteristics and factors in cross-sectional regressions finds a higher number of corporate bond, rather than stock, characteristics and factors that predict the cross-section of corporate bond returns when adjusting for higher benchmarks. In addition to the lower number of corporate bond characteristics and factors that predict the cross-section of stock returns, my results show that the stock and corporate bond markets are more segmented than previously documented.My second essay is based on a joint working paper entitled "Do Option Implied Measures of Stock Mispricing Find Investment Opportunities or Market Frictions" where we find that existing option implied stock mis-pricing measures, the portfolios identified as being the most mispriced (highest quintile), typically have the highest shorting fee. When those stocks are omitted, the average abnormal returns of the long-short stock portfolios are insignificant or greatly reduced in economic magnitude. We propose a new measure, IPD, using a novel intra-day options trades data set, circumvents this and does not require shorting hard to borrow firms.My third essay is based on a joint working paper entitled "Accounting Transparency and the Implied Volatility Skew". We show theoretically and empirically that firms with higher accounting transparency have an implied volatility smirk that is more sensitive to leverage (vice versa). The more clear the accounting information the more skewed the implied volatility smirk. Our theoretical predictions rely on extending the Duffie and Lando [2001] credit risk model to stock option pricing whereby incomplete accounting information and the risk of bankruptcy together act as an economic source of jump risk for stocks. Empirical tests confirm the theoretical predictions of the model and the model can be solved in closed form solution up to Bivariate Standard Normal Cumulative Distribution Function"--

Book Description
"This thesis consists of three essays that explore alternative approaches to extracting information from option data, and, along somewhat different lines, examine the channels through which liquidity is priced in equity options.The first essay proposes a novel approach to extracting option-implied equity premia, and empirically examines the information content of these risk premia for forecasting the stock market return. Our approach does not require specifying the functional form of the pricing kernel, and does not impose any restrictions on investors' preferences. We only assume the existence of put and call options which complete the market, and show that the implied equity premium can be inferred from expected excess returns on a portfolio of options. An empirical investigation of S&P 500 index options yields the following conclusions: (i) the implied equity premium predicts stock market returns; (ii) the implied equity premium consistently outperforms variables commonly used in the forecasting literature both in- and out-of-sample; (iii) the implied equity premium is positively related to future returns and negatively related to current returns, as theoretically expected.The second essay studies the effect of illiquidity on equity option returns. Illiquidity is well-known to be a significant determinant of stock and bond returns. We are the first to report on illiquidity premia in equity option markets using a large cross-section of firms. An increase in option illiquidity decreases the current option price and predicts higher expected delta-hedged option returns. This effect is statistically and economically significant, and it is consistent with existing evidence that market makers in the equity options market hold net long positions. The illiquidity premium is robust across puts and calls, across maturities and moneyness, as well as across different empirical approaches. It is also robust when controlling for various firm-specific variables including a standard measure of illiquidity of the underlying stock. For long term options, we find evidence of a liquidity risk factor. In the third essay, we demonstrate that in multifactor asset pricing models, prices of risk for factors that are nonlinear functions of the market return can be readily obtained using data on index returns and index options. We apply this general result to the measurement of the conditional price of coskewness and cokurtosis risk. The price of coskewness risk corresponds to the spread between the physical and the risk-neutral second moments, and the price of cokurtosis risk corresponds to the spread between the physical and the risk-neutral third moments. Estimates of these prices of risk have the expected sign, and they lead to reasonable risk premia. An out-of-sample analysis of factor models with coskewness and cokurtosis risk indicates that the new estimates of the price of risk improve the models. performance. The models also robustly outperform competitors such as the CAPM and the Fama-French model." --
