Book Description
The stock market, according to the efficient market hypothesis, is informationally efficient in that prices instantly reflect all available public information. Prior financial literature on the study of the relationship between earnings announcements and their effect on the stock market reveals that there is a significant "drift" of a firm's cumulative abnormal return that occurs in the direction of its earnings surprise. This phenomenon is in contrast to how the efficient market hypothesis would expect the market to react to this new information. The prior studies on this topic were conducted in the 1980s - before the existence of both high-speed access to news via cell phone alerts and the increasing ability to trade quickly on new information via online brokers. This study attempts to test this "post-earnings announcement drift" on the current market to see if this phenomenon is still relevant in today's market and to see if it can be exploited. This study finds that there is still a post-earnings announcement drift that persists for the twenty-one days following earnings announcements. The cumulative abnormal returns continue to drift upwards for "good news" firms and continue to drift downwards for "bad news" firms for twenty-one days and may continue in the same direction after this period. This study also finds that a trading strategy that involves forming long portfolios of firms that beat earnings by the greatest magnitude (most positive earnings surprise) and also have the largest abnormal return on the day of the announcement and forming a short portfolio of firms that miss estimates by the greatest magnitude (most negative earnings surprise) and have the most negative abnormal return on the day of the announcement had an average annualized return of 20.343% over the ten year period starting in 2004 while the S & P 500 had an average annualized return of 9.1% over the same period.

Book Description
Prior research has been unable to explain the phenomenon known as post-earnings announcement drift, raising questions concerning the semi-strong form efficiency of the market typically assumed in capital market research. This study contributes to our understanding of this anomaly by examining drift in the context of theories that consider investors' non-Bayesian behaviors. The empirical evidence reveals that investors' overconfidence about their private information and the reliability of the earnings information are two important factors that explain drift. Finally, this study also provides insight into the puzzling relationship between dispersion and drift discussed in prior research.

Book Description
The solution as to why Post Earnings Announcement Drift (PEAD) occurs has eluded academic experts in the field for almost fifty years. Furthermore, because it conflicts with the widely accepted Efficient Market Hypothesis (EMH), it has drawn a great deal of attention. Due to the longevity of its mystery as well as the controversy it causes as a counterargument to EMH, PEAD has become one of the most interesting and researched financial topics of all time. Previous research has narrowed down the list of possibilities for the potential cause of this phenomenon and this work will add to the literature by examining a logical possibility, ownership style. This study will compare Post Earnings Announcement Drift in firms that are owned mostly by active investors against those who are more largely owned by passive investors. This would imply a lack of attention, trading, and liquidity as the root cause of PEAD.

Book Description
This study addresses the issue of post-earnings-announcement drift. According to the present theory of how capital markets behave, the drift cannot occur if either the capital asset pricing model (CAPM) or the efficient market hypothesis (EMH) is valid. The drift is a drift away from the CAPM price, which means that CAPM cannot be how the market mechanically determines prices. The drift has been known since at least 1968, which means that an allegedly efficient market knows of the drift, yet does not take the drift into account in setting prices and thereby drive the drift out of existence. The existence of the drift means that the market cannot be completely efficient even within a time frame of three months.This article uses economic modeling to analyze the drift and the results of a field study to explain why it occurs. This article also explains (1) why the size of the drift varies by size of the company, (2) that the market is not efficient, (3) why stock prices tend to rise after a stock split, and (4) some of the incentives for managements to smooth earnings.

Book Description
It is a well documented finding in finance theory that share prices drift in the direction of firms' unexpected earnings changes, a phenomenom known as post-earnings announcement drift, or earnings momentum. In this book, I study the stock prices' reaction to firms' quarterly earnings announcements. The book shows that the timeframe in which the drift occurs is related to the size of a firm and is limited in time after the earnings announcement. I further analyze the effect of the number of analysts covering a firm on the magnitude and persistance of post-earnings announcement drift. I document that recent analyst coverage predicts large drifts after the earnings announcements. I suggest several possible explanations, but the evidence seems most consistent with recent analyst coverage providing information about investor (or analyst) expectations regarding firm's future earnings. This book should be useful to professionals in Financial Economics, especially to those interested in Behavioral Finance in stock markets, but also to equity analysts, traders or investors interested in the stocks' response to earnings news.

Book Description
The existence of post earnings announcement drift (PEAD) depends strongly on whether stocks' prices are near (far from) their 52-week highs when positive (negative) earnings surprises arrive. We find that the coincidence of these two effects is what generates significant PEAD. Daily returns around current and future earnings announcements follow a similar pattern -- announcement returns are more muted for extreme positive (negative) surprises, the closer (farther) are prices to the 52-week high. In addition, subsequent announcement returns are greater for these firms, consistent with a correction of previous underreaction. This suggests that an important contributing factor to PEAD is investors anchoring their beliefs about fundamental value on the 52-week high, which restrains price reactions to earnings news.

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.

Book Description
We examine whether the post-earnings announcement drift (PEAD) varies cross-sectionally with short-horizon return predictability from order flows, which characterizes the information environment and reflects the extent to which information is efficiently impounded in prices. We first demonstrate that this proxy for market efficiency (developed by Chordia, Roll, and Subrahmanyam 2008) captures the degree of market frictions that limit arbitrage activities. We then present evidence that the inverse of short-horizon return predictability is negatively associated with the PEAD and remains statistically and economically significant after controlling for a wide range of explanatory variables used in prior research. Finally, although we find that profits of implementing the PEAD trading strategy are significantly reduced by transaction costs, we demonstrate that profits continue to remain statistically and economically significant for the less efficient firms that face otherwise higher barriers to arbitrage. Our results indicate that short-horizon return predictability from order flows better explains stock returns after earnings announcements.
