Book Description
This paper investigates the relation between the post-earnings-announcement drift anomaly and liquidity. First, we find that, on average, bad-news firms (low standardized unexpected earnings (SUE)) are less liquid than good-news firms (high SUE), reflecting more information asymmetry and/or uncertainty among bad-news firms. Yet, we argue that this liquidity spread is less likely to explain the drift. Second, the returns of SUE-sorted portfolios are sensitive to fluctuations in market-wide liquidity. We find that systematic liquidity risk is an important determinant in explaining the cross-sectional variation of expected returns among SUE-sorted portfolios. This implies that a substantial part of the post-earnings-announcement drift anomaly can be viewed as compensation for risk associated with shocks to the information environment in the economy. Therefore, the evidence suggests that the previously reported anomalous returns are associated with model misspecification and/or hidden transaction costs.

Book Description
This paper investigates the components of liquidity risk that are important for asset-pricing anomalies. Firm-level liquidity is decomposed into variable and fixed price effects and estimated using intraday data for the period 1983-2001. Unexpected systematic (market-wide) variations of the variable component rather than the fixed component of liquidity are shown to be priced within the context of momentum and post-earnings-announcement drift (PEAD) portfolio returns. As the variable component is typically associated with private information (e.g., Kyle (1985)), the results suggest that a substantial part of momentum and PEAD returns can be viewed as compensation for the unexpected variations in the aggregate ratio of informed traders to noise traders.

Book Description
This study explores an additional factor that is associated with differential levels of the post-earnings-announcement drift (henceforth drift) - the contemporaneous surprise in revenues. Consistent with prior evidence about greater persistence of revenues and greater noise caused by heterogeneity of expenses, this study shows that the earnings drift is stronger when the revenue surprise is in the same direction as the earnings surprise. Moreover, the study provides direct evidence that the drift is stronger when the earnings persistence is greater. The results are robust to various controls, including the proportions of stock held by institutional investors, trading liquidity, and arbitrage risk.

Book Description
The persistence of the post-earnings announcement drift leads many to believe that trading barriers prevent knowledgeable investors from eliminating it. For example, Bhushan (1994) contends that sophisticated investors quickly drive prices to within trading costs of efficient values. We examine two factors not previously addressed in the literature: the exact timing of the announcements and liquidity costs. Specifically, we compare the profits generated by transacting immediately following the announcement and at the close of the actual announcement day to the common practices of assuming trades at the close on the Compustat date or the following day. We further investigate the impact of liquidity costs on the drift by examining actual quotes available to investors. Under a wide range of timing and cost assumptions our results leave little doubt that between 1993 and 2002 an investor could have earned hedged-portfolio returns of at least 14% per year after trading costs.

Book Description
The post-earnings-announcement-drift is a long standing anomaly that is in conflict with market efficiency. This paper documents that the post-earnings-announcement drift occurs mainly in the highly illiquid stocks. A trading strategy that goes long the high earnings surprise stocks and short the low earnings surprise stocks provides a value-weighted return of 0.14% in the most liquid stocks and 1.60% per month in the most illiquid stocks. The illiquid stocks have high trading costs and market impact costs. Using a multitude of estimates we find that transaction costs account for anywhere from 63% to 100% of the paper profits from the long-short strategy designed to exploit the earnings momentum anomaly. This paper provides support for the argument that transactions costs could be the source of the drift.

Book Description
We examine the role of investors' beliefs in determining the post earnings announcement drift (PEAD). Specifically, we propose a technique to estimate the belief parameters of the informed and uninformed investors, based on which we define the uninformed investors' information acceptance ratio (IAR). We demonstrate that IAR is a key factor determining the length of PEAD. IAR also explains the post announcement returns and the risk increases. Furthermore, we show that the earnings announcements contain both the hard and soft information. The hard information reduces uncertainty, whereas the soft information enhances uncertainty. And the latter effect dominates the former.

Book Description
Investment pioneer Len Zacks presents the latest academic research on how to beat the market using equity anomalies The Handbook of Equity Market Anomalies organizes and summarizes research carried out by hundreds of finance and accounting professors over the last twenty years to identify and measure equity market inefficiencies and provides self-directed individual investors with a framework for incorporating the results of this research into their own investment processes. Edited by Len Zacks, CEO of Zacks Investment Research, and written by leading professors who have performed groundbreaking research on specific anomalies, this book succinctly summarizes the most important anomalies that savvy investors have used for decades to beat the market. Some of the anomalies addressed include the accrual anomaly, net stock anomalies, fundamental anomalies, estimate revisions, changes in and levels of broker recommendations, earnings-per-share surprises, insider trading, price momentum and technical analysis, value and size anomalies, and several seasonal anomalies. This reliable resource also provides insights on how to best use the various anomalies in both market neutral and in long investor portfolios. A treasure trove of investment research and wisdom, the book will save you literally thousands of hours by distilling the essence of twenty years of academic research into eleven clear chapters and providing the framework and conviction to develop market-beating strategies. Strips the academic jargon from the research and highlights the actual returns generated by the anomalies, and documented in the academic literature Provides a theoretical framework within which to understand the concepts of risk adjusted returns and market inefficiencies Anomalies are selected by Len Zacks, a pioneer in the field of investing As the founder of Zacks Investment Research, Len Zacks pioneered the concept of the earnings-per-share surprise in 1982 and developed the Zacks Rank, one of the first anomaly-based stock selection tools. Today, his firm manages U.S. equities for individual and institutional investors and provides investment software and investment data to all types of investors. Now, with his new book, he shows you what it takes to build a quant process to outperform an index based on academically documented market inefficiencies and anomalies.
