Return Asymmetry and the Cross Section of Stock Returns


Book Description

This paper develops a new measure of return asymmetry, following Patil et al. (2012). We demonstrate that the return asymmetry measure helps explain the cross section of stock returns. Consistent with results in Barberis and Huang (2008), our empirical findings show that stocks with high return asymmetry exhibit low expected returns. The negative relation between return asymmetry and the cross section of stock returns persists for up to the 12-month forecast horizon and remains robust after controlling for the effects of skewness.




Option-Implied Variance Asymmetry and the Cross-Section of Stock Returns


Book Description

We find a positive relationship between individual stocks' implied variance asymmetry, defined as the difference between upside and downside risk-neutral semivariances extracted from out-of-money options, and future stock returns. The high-minus-low hedge portfolio earns the excess return of 0.90% (0.67%) per month in equal-weighted (value-weighted) returns. We show that implied variance asymmetry provides a neat measure of risk-neutral skewness and outperforms the standard risk-neutral skewness in predicting the cross-section of future stock returns. Risk-based equilibrium asset pricing models can not explain such a positive relationship, which instead can be potentially explained by information asymmetry and informed trading.







Asymmetric Risk Loadings in the Cross Section of Stock Returns


Book Description

Time-varying factor loadings exhibit pronounced asymmetry in the cross section of stock returns. To capture this asymmetry, we develop regime-switching versions of the CAPM and the Fama French three-factor model, allowing both factor loadings and predictable risk premiums to switch across regimes. We estimate the models jointly on the decile book-to-market portfolios, together with the market portfolio to investigate the role of asymmetric risk in the book-to-market premium. We find that betas of value stocks increase significantly during bear market episodes. However, we still reject that the book-to-market premium is equal to zero for both the regime-switching conditional CAPM and the Fama-French model, even in the presence of regimes.







Irrational Exuberance Reconsidered


Book Description

Mathias Külpmann presents a framework to evaluate whether the stock market is in line with underlying fundamentals. The new and revised edition offers an up to date introduction to the controversy between rational asset pricing and behavioural finance. Empirical evidence of stock market overreaction are investigated within the paradigms of rational asset pricing and behavioural finance. Although this monograph will not promise the reader to become a millionaire, it offers a road to obtain a deeper understanding of the forces which drive stock returns. It should be of interest to anyone interested in what drives performance in the stock market.




The Bulls and Bears in the Cross-Section of Stock Returns


Book Description

Many financial decision-makers seem to regard risk as the variability of returns below some pre-specified target and treat above-target variability as a sweetener. The disutility from losses also appears to be larger than the utility from gains. Using some simple metrics of downside bearishness and upside bullishness constructed from semivariances, this paper tests for the empirical content of this asymmetry. Some of these simple metrics are priced in the U.S. stock market. In particular, exploring a composite metric of asymmetric risk reveals that non-linearity in the covariation of stock returns with bullish and bearish states of the market carries a significant price. Also, market premium for bearishness is larger in magnitude than that for bullishness, lending support to the existence of loss aversion in the aggregate. While small-cap stocks tend to be more bearish than bullish, the asymmetric risk effect is not spuriously driven by the size effect. Finally, some results consistent with an aymmetric-risk-based explanation for the puzzles of return momentum and reversal are presented.




Nonparametric Econometrics


Book Description

A comprehensive, up-to-date textbook on nonparametric methods for students and researchers Until now, students and researchers in nonparametric and semiparametric statistics and econometrics have had to turn to the latest journal articles to keep pace with these emerging methods of economic analysis. Nonparametric Econometrics fills a major gap by gathering together the most up-to-date theory and techniques and presenting them in a remarkably straightforward and accessible format. The empirical tests, data, and exercises included in this textbook help make it the ideal introduction for graduate students and an indispensable resource for researchers. Nonparametric and semiparametric methods have attracted a great deal of attention from statisticians in recent decades. While the majority of existing books on the subject operate from the presumption that the underlying data is strictly continuous in nature, more often than not social scientists deal with categorical data—nominal and ordinal—in applied settings. The conventional nonparametric approach to dealing with the presence of discrete variables is acknowledged to be unsatisfactory. This book is tailored to the needs of applied econometricians and social scientists. Qi Li and Jeffrey Racine emphasize nonparametric techniques suited to the rich array of data types—continuous, nominal, and ordinal—within one coherent framework. They also emphasize the properties of nonparametric estimators in the presence of potentially irrelevant variables. Nonparametric Econometrics covers all the material necessary to understand and apply nonparametric methods for real-world problems.




Return Dispersion, Size, and the Cross-Section of Stock Returns - Evidence from the German Stock Market


Book Description

This paper investigates whether return dispersion (RD), proxied by the cross-sectional standard deviation of stock returns, captures variation in returns across German stocks between 1989 and 2010. I address existing evidence based on U.S. equity data that RD may serve as a proxy economic state variable. In the out-of-sample test I confirm the countercyclical character of RD and show that it loads significantly negatively on future equal-weighted average market return. Sorting stocks by their absolute loadings on RD, I uncover the negative pattern in simple average portfolio returns. Further analysis indicates that the negative relationship between absolute loadings on RD and future returns is present only in micro stock subgroup. This finding casts doubt on the RD as proxy for state variable. Instead, it suggests its relation to mispricing and idiosyncratic risk components. As a secondary results I confirm the existence of reversed size effect in German stock market over the considered period.




Skewness and Dispersion of Opinion and the Cross Section of Stock Returns


Book Description

We show that the degree of dispersion and asymmetry of analysts' earnings forecasts is related to future stock returns. When skewness is negative, future returns are decreasing in the degree of dispersion of analysts' earnings forecasts; when skewness is positive, future returns are increasing in the degree of dispersion of analysts earnings forecasts. We develop a model that incorporates dispersion and asymmetry in agents' beliefs that can account for these empirical facts.
