Available in PDF, EPUB and Kindle. Book excerpt: (cont.) I focus on the general case in which differential information leads to the problem of "forecasting the forecasts of others" and to non-trivial dynamics of higher order expectations. I prove that the model does not admit a finite number of state variables. Using numerical analysis, I compare equilibria characterized by identical fundamentals but different information structures and show that the distribution of information has substantial impact on equilibrium prices and returns. In particular, asymmetric information might generate predictability in returns and high trading volume.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation studies the effect of parameter uncertainty on the return predictability and volatility of the stock market. The first two chapters focus on the decomposition of market volatility, and the third chapter studies the return predictability. When facing imperfect information, the investors tend to form a learning scheme that encompasses both historical data and prior beliefs. In the variance decomposition framework, the introducing of learning directly impacts the way that return forecasts are revised and consequently the relative component of market volatility based on these forecasts, namely the price movements from revision on future discount rates and those from future cash flows. According to the empirical study in Chapter 1, the former is not necessarily the major driving force of market volatility, which provides an alternative view on what moves stock prices. Learning is modeled and estimated by Bayesian method. Chapter 2 follows the topic in Chapter 1 and studies the role of persistent state variables in return decomposition in order to provide more robust inference on variance decomposition. In Chapter 3 we propose to utilize theoretical constraints to help predict market returns when in sample data is very noisy and creates model uncertainty for the investors. The constraints are also incorporated by Bayesian method. We show in the out-of-sample forecast experiment that models with theoretical constraints produce better forecasts.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation collects two papers regarding the econometric and economic theory and testing of the predictability of asset returns. It is widely accepted that stock returns are not only predictable but highly so. This belief is due to an abundance of existing empirical literature finding often overwhelming evidence in favor of predictability. The common regressors used to test predictability (e.g., the dividend-price ratio for stock returns) are very persistent and their innovations are highly correlated with returns. Persistence when combined with a correlation between innovations in the regressor and asset returns can cause substantial over-rejection of a true null hypothesis. This result is both well documented and well known. On the other hand, stochastic volatility is both broadly accepted as a part of return time series and largely ignored by the existing econometric literature on the predictability of returns. The severe effect that stochastic volatility can have on standard tests are demonstrated here. These deleterious effects render standard tests invalid. However, this problem can be easily corrected using a simple change of chronometer. When a return time series is read in the usual way, at regular intervals of time (e.g., daily observations), then the distribution of returns is highly non-normal and displays marked time heterogeneity. If the return time series is, instead, read according to a clock based on regular intervals of volatility, then returns will be independent and identically normally distributed. This powerful result is utilized in a unique way in each chapter of this dissertation. This time-deformation technique is combined with the Cauchy t-test and the newly introduced martingale estimation technique. This dissertation finds no evidence of predictability in stock returns. Moreover, using martingale estimation, the cause of the Forward Premium Anomaly may be more easily discerned.

Book excerpt: The dissertation consists of two essays. Essay I examines the return predictability by firm level R & D and innovation measures and shows that technology spillover helps to explain the positive innovation-return relation. Essay II propose a novel measure of conditional value premium based on firm's stock split announcement. This measure is shown to have a strong predicting power over value premium both in sample and out of sample. Essay I: I show that technology spillovers are important information phenomena that benefit both other innovators (as emphasized in the Industrial Organization literature) and stock market investors. I find that the premium associated with R & D and patenting activities is largely restricted to firms located in more isolated technology spaces with fewer spillovers. Moreover, there is a strong lead-lag effect among firms engaging in innovative activities: the stock prices of firms in more isolated technology spaces react more slowly to new information than do the stock prices of firms in more competitive technology spaces. Finally, announcement-day returns to patent grants are greater for more technologically important patents (measured by forward citations), but only for firms in more crowded technology spaces. My results indicate that investors are able to value innovative investments by exploiting the information flows associated with greater technology spillovers. Essay II: I propose a novel conditional value premium measure based on the present-value relation that the stock price impact of a firm's public announcement reveals the firm's expected discount rates. Specifically, because most splitting stocks are growth stocks on which, by construction, the value premium has strong influence, the average splitting stock announcement-day returns track closely conditional value premium. I find very similar results using announcements of divested asset acquisitions in which acquirers are usually growth firms. Consistent with risk-based explanations, my conditional value premium measure correlates positively with future GDP growth and helps explain the cross-section of stock returns.

Available in PDF, EPUB and Kindle. Book excerpt: My dissertation consists of three chapters that study various aspects of stock return predictability. In the first chapter, I explore the interplay between the aggregation of information about stock returns and p-hacking. P-hacking refers to the practice of trying out various variables and model specifications until the result appears to be statistically significant, that is, the p-value of the test statistic is below a particular threshold. The standard information aggregation techniques exacerbate p-hacking by increasing the probability of the type I error. I propose an aggregation technique, which is a simple modification of 3PRF/PLS, that has an opposite property: the predictability tests applied to the combined predictor become more conservative in the presence of p-hacking. I quantify the advantages of my approach relative to the standard information aggregation techniques by using simulations. As an illustration, I apply the modified 3PRF/PLS to three sets of return predictors proposed in the literature and find that the forecasting ability of combined predictors in two cases cannot be explained by p-hacking. In the second chapter, I explore whether the stochastic discount factors (SDFs) of five characteristic-based asset pricing models can be explained by a large set of macroeconomic shocks. Characteristic-based factor models are linear models whose risk factors are returns on trading strategies based on firm characteristics. Such models are very popular in finance because of their superior ability to explain the cross-section of expected stock returns, but they are also criticized for their lack of interpretability. Each characteristic-based factor model is uniquely characterized by its SDF. To approximate the SDFs by a comprehensive set of 131 macroeconomic shocks without overfitting, I employ the elastic net regression, which is a machine learning technique. I find that the best combination of macroeconomic shocks can explain only a relatively small part of the variation in the SDFs, and the whole set of macroeconomic shocks approximates the SDFs not better than only few shocks. My findings suggest that behavioral factors and sentiment are important determinants of asset prices. The third chapter investigates whether investors efficiently aggregate analysts' earnings forecasts and whether combinations of the forecasts can predict announcement returns. The traditional consensus forecast of earnings used by academics and practitioners is the simple average of all analysts' earnings forecasts (Naive Consensus). However, this measure ignores that there exists a cross-sectional variation in analysts' forecast accuracy and persistence in such accuracy. I propose a consensus that is an accuracy-weighted average of all analysts' earnings forecasts (Smart Consensus). I find that Smart Consensus is a more accurate predictor of firms' earnings per share (EPS) than Naive Consensus. If investors weight forecasts efficiently according to the analysts' forecast accuracy, the market reaction to earnings announcements should be positively related to the difference between firms' reported earnings and Smart Consensus (Smart Surprise) and should be unrelated to the difference between firms' reported earnings and Naive Consensus (Naive Surprise). However, I find that market reaction to earnings announcements is positively related to both measures. Thus, investors do not aggregate forecasts efficiently. In addition, I find that the market reaction to Smart Surprise is stronger in stocks with higher institutional ownership. A trading strategy based on Expectation Gap, which is the difference between Smart and Naive Consensuses, generates positive risk-adjusted returns in the three-day window around earnings announcements.

Book excerpt: This dissertation consists of three essays on stock market volatility. In the first essay, we show that investors will have the information in the idiosyncratic volatility spread when using two different models to estimate idiosyncratic volatility. In a theoretical framework, we show that idiosyncratic volatility spread is related to the change in beta and the new betas from the extra factors between two different factor models. Empirically, we find that idiosyncratic volatility spread predicts the cross section of stock returns. The negative spread-return relation is independent from the relation between idiosyncratic volatility and stock returns. The result is driven by the change in beta component and the new beta component of the spread. The spread-relation is also robust when investors estimate the spread using a conditional model or EGARCH method. In the second essay, the variance of stock returns is decomposed based on a conditional Fama-French three-factor model instead of its unconditional counterpart. Using time-varying alpha and betas in this model, it is evident that four additional risk terms must be considered. They include the variance of alpha, the variance of the interaction between the time-varying component of beta and factors, and two covariance terms. These additional risk terms are components that are included in the idiosyncratic risk estimate using an unconditional model. By investigating the relation between the risk terms and stock returns, we find that only the variance of the time-varying alpha is negatively associated with stock returns. Further tests show that stock returns are not affected by the variance of time-varying beta. These results are consistent with the findings in the literature identifying return predictability from time-varying alpha rather than betas. In the third essay, we employ a two-step estimation method to separate the upside and downside idiosyncratic volatility and examine its relation with future stock returns. We find that idiosyncratic volatility is negatively related to stock returns when the market is up and when it is down. The upside idiosyncratic volatility is not related to stock returns. Our results also suggest that the relation between downside idiosyncratic volatility and future stock returns is negative and significant. It is the downside idiosyncratic volatility that drives the inverse relation between total idiosyncratic volatility and stock returns. The results are consistent with the literature that investor overreact to bad news and underreact to good news.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation studies two distinct topics. First, I examine whether the idiosyncratic volatility discount anomaly documented by Ang, Hodrick, Xing, and Zhang (2006, 2009) is related to earnings shocks, and I find that a substantial portion of the idiosyncratic volatility discount can be explained by earnings momentum and post-formation earnings shocks. When these two effects are accounted for, idiosyncratic volatility has little, if any, return predictability. Second, I propose a parsimonious measure to characterize the severity of the microstructure noise at the individual stock level and assess the impact of this microstructure induced illiquidity on cross-sectional return predictability. One of the main advantages of this measure is that it is very simple to construct (requires only daily stock returns data). Using this measure I find that firms with the largest microstructure bias command a return premium as large as 9.61% per year, even after controlling for the premiums associated with size, book-to-market, momentum, and traditional liquidity price impact and cost measures. In addition, the bias premium is strongest among small, low price, volatile, and illiquid stocks. On the other hand, the premiums associated with size, illiquidity, and return reversal are most pronounced among stocks with the largest bias.
