Book Description
Several studies have attributed the high excess returns of the momentum strategy in the equity market to investor behavioral biases. However, whether momentum effects occur because of investor underreaction or because of investor overreaction remains a question. Using a simple model to illustrate the linkage between idiosyncratic volatility and investor overreaction as well as the stock turnover as another measure of overreaction, I present evidence that supports the investor overreaction explanation as the source of momentum effects. Furthermore, I show that when investor overreaction is low, momentum effects are more due to industries (industry momentum) rather than stocks.

Book Description
The finding that stocks with high idiosyncratic volatility tend to have low future returns has been dubbed an empirical anomaly in the finance literature. We seek to understand this puzzle by separating the upside volatility associated with positive idiosyncratic returns from the downside risk associated with negative idiosyncratic returns. We find that downside risk is not inversely related to future stock returns, thus easing the concern that the empirical anomaly is a mispricing of risk. Rather, our results suggest that it is upside volatility that drives the inverse idiosyncratic volatility and return relation. We further examine whether the relation of future returns with downside and upside volatility accords with investor underreaction to bad news and overreaction to good news. Finally, we show that momentum strategies may be enhanced by taking into account stocks' upside volatility.

Book Description
Recent evidence on the relation between momentum and idiosyncratic volatility (IV) in the U.S. is mixed. We verify the relation between momentum and IV in China and find at best, no relation supporting the view that idiosyncratic risk is not a significant arbitrage cost for momentum returns. While the absence of a positive relation between momentum returns and IV rejects both the underreaction and the overconfidence and self-attribution stories of momentum, we find support for the overconfidence and self-attribution story from our results on market dynamics and momentum. Our results are robust when verified in other Asian markets. We also find support for the suggestion that cross-country differences in momentum returns could be the result of differences in market dynamics rather than differences in levels of individualism as suggested earlier in the literature.

Book Description
This paper extends the literature on market reaction to extreme price changes by introducing an empirical model that allows the conditional mean and variance of returns to vary asymmetrically in response to price changes of all sizes. We provide evidence, from US, UK and Japanese markets, that conditional returns do depend on the size and sign of previous price changes although there are strong indications that the effect has declined over time. We find support for the recently developed asset pricing models in which economic agents display behavioral biases and simultaneously underreact to some types of events and overreact to others. Our results show that the market tends to reverse after large price changes, while after small price changes a momentum type effect is observed.

Book Description
Price volatility and investor overreactions are commonplace in experimental asset markets. Understanding the price dynamics in these markets is crucial for designing successful new trading institutions. We report on a series of experiments to test the predictions of a new momentum model using a dynamical systems approach. This model is then pitted against several standard models to predict prices, as well as against expert human forecasters. The comparative results suggest that each model has its advantages and regions of best performance. Overall, the best predictive methods are the momentum model and expert human forecasters.

Book Description
This article demonstrates that momentum, term structure and idiosyncratic volatility signals in commodity futures markets are not overlapping which inspires a novel triple-screen strategy. We show that simultaneously buying contracts with high past performance, high roll-yields and low idiosyncratic volatility, and shorting contracts with poor past performance, low roll-yields and high idiosyncratic volatility yields a Sharpe ratio over the 1985 to 2011 period which is five times that of the S&P-GSCI. The triple-screen strategy dominates the double-screen and individual strategies and this outcome cannot be attributed to overreaction, liquidity risk, transaction costs or the financialization of commodity futures markets.

Book Description
“Bali, Engle, and Murray have produced a highly accessible introduction to the techniques and evidence of modern empirical asset pricing. This book should be read and absorbed by every serious student of the field, academic and professional.” Eugene Fama, Robert R. McCormick Distinguished Service Professor of Finance, University of Chicago and 2013 Nobel Laureate in Economic Sciences “The empirical analysis of the cross-section of stock returns is a monumental achievement of half a century of finance research. Both the established facts and the methods used to discover them have subtle complexities that can mislead casual observers and novice researchers. Bali, Engle, and Murray’s clear and careful guide to these issues provides a firm foundation for future discoveries.” John Campbell, Morton L. and Carole S. Olshan Professor of Economics, Harvard University “Bali, Engle, and Murray provide clear and accessible descriptions of many of the most important empirical techniques and results in asset pricing.” Kenneth R. French, Roth Family Distinguished Professor of Finance, Tuck School of Business, Dartmouth College “This exciting new book presents a thorough review of what we know about the cross-section of stock returns. Given its comprehensive nature, systematic approach, and easy-to-understand language, the book is a valuable resource for any introductory PhD class in empirical asset pricing.” Lubos Pastor, Charles P. McQuaid Professor of Finance, University of Chicago Empirical Asset Pricing: The Cross Section of Stock Returns is a comprehensive overview of the most important findings of empirical asset pricing research. The book begins with thorough expositions of the most prevalent econometric techniques with in-depth discussions of the implementation and interpretation of results illustrated through detailed examples. The second half of the book applies these techniques to demonstrate the most salient patterns observed in stock returns. The phenomena documented form the basis for a range of investment strategies as well as the foundations of contemporary empirical asset pricing research. Empirical Asset Pricing: The Cross Section of Stock Returns also includes: Discussions on the driving forces behind the patterns observed in the stock market An extensive set of results that serve as a reference for practitioners and academics alike Numerous references to both contemporary and foundational research articles Empirical Asset Pricing: The Cross Section of Stock Returns is an ideal textbook for graduate-level courses in asset pricing and portfolio management. The book is also an indispensable reference for researchers and practitioners in finance and economics. Turan G. Bali, PhD, is the Robert Parker Chair Professor of Finance in the McDonough School of Business at Georgetown University. The recipient of the 2014 Jack Treynor prize, he is the coauthor of Mathematical Methods for Finance: Tools for Asset and Risk Management, also published by Wiley. Robert F.
