The efficient market hypothesis (EMH) maintains that all relevant information is fully and immediately reflected in stock prices and that investors will obtain an equilibrium rate of return. The EMH has far reaching implications for capital allocation, stock price prediction, and the effectiveness of specific trading strategies. Equity market anomalies reflect that the market is inefficient and hence, contradicts the EMH. This book gathers both theoretical and practical perspectives, by including research issues, methodological approaches, practical case studies, uses of new policy and other points of view related to equity market efficiency to help address the future challenges facing the global equity markets and economies. Information Efficiency and Anomalies in Asian Equity Markets: Theories and evidence is an insightful resource that will be useful for students, academics and professionals alike.

The Efficient Market Hypothesis believes that it is impossible for an investor to outperform the market because all available information is already built into stock prices. However, some anomalies could persist in stock markets while some other anomalies could appear, disappear and re-appear again without any warning. A Special Issue on "Efficiency and Anomalies in Stock Markets" will be devoted to advancements in the theoretical development of market efficiency and anomaly in the Stock Market, as well as applications in Stock Market efficiency and anomalies.

"This paper examines the random walk behaviour of a large number of Asian emerging and developed markets. Past studies of random walks and market efficiency in Asian equity markets have tended to focus on a single, often developed, market [see, for example, Groenewold and Kang (1993), Ayadi and Pyun (1994), Lian and Leng (1994), Huang (1995), Groenewold and Ariff (1998), Los (2000), Lee et al. (2001) and Ryoo and Smith (2002)]. The current analysis also includes a number of alternative, though complementary, testing procedures"--Page 3.

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.

The Efficient Market Hypothesis (EMH) asserts that, at all times, the price of a security reflects all available information about its fundamental value. The implication of the EMH for investors is that, to the extent that speculative trading is costly, speculation must be a loser's game. Hence, under the EMH, a passive strategy is bound eventually to beat a strategy that uses active management, where active management is characterized as trading that seeks to exploit mispriced assets relative to a risk-adjusted benchmark. The EMH has been refined over the past several decades to reflect the realism of the marketplace, including costly information, transactions costs, financing, agency costs, and other real-world frictions. The most recent expressions of the EMH thus allow a role for arbitrageurs in the market who may profit from their comparative advantages. These advantages may include specialized knowledge, lower trading costs, low management fees or agency costs, and a financing structure that allows the arbitrageur to undertake trades with long verification periods. The actions of these arbitrageurs cause liquid securities markets to be generally fairly efficient with respect to information, despite some notable anomalies.

The efficiency of speculative markets, as represented by Fama's 1970 fair game model, is tested on weekly price index data of six Asian stock markets - Hong Kong, Indonesia, Malaysia, Singapore, Taiwan and Thailand - using Sherry's (1992) non-parametric methods. These scientific testing methods were originally developed to analyze the information processing efficiency of nervous systems. In particular, the stationarity and independence of the price innovations are tested over ten years, from June 1986 to July 1996. These tests clearly show that all six stock markets lacked at least one of the two required fair game attributes, and, accordingly, Fama's Efficient Market Hypothesis must be rejected for these Asian markets. However, Singapore emerged from these tests as the most efficient regional Asian stock market. A tentative ranking in order of stock market efficiency is: Singapore, Thailand, Indonesia, Malaysia, Hong Kong and Taiwan. Singapore's stock market pricing is closest to the speculative market behavior which can support stock options. Our tests show both Hong Kong and Taiwan to be inefficient markets. Both exhibit non-stationary (likely because of continuing institutional changes) and dependent price innovations, making them particularly unsuitable for stock option pricing. In Taiwan the weekly price innovations show even higher order (Markov) dependencies. Although the price innovations in Malaysia, Thailand and Indonesia are at least stationary at the weekly level, they exhibit regular higher-order transitions and the large sustained movements in both bull and bear markets, which are so characteristic for illiquid emerging markets. All six Asian stock markets exhibit strong price trend behavior, which, perhaps, can be profitably exploited by technical analysis with first-order Markov filters (e.g., Kalman filters) in windows of between a week and more than a month.

Market efficiency is an important feature of successful financial markets. The aim of this paper is to analyze the available evidence on the efficient market hypothesis (EMH). Meta-regression analysis is applied to 1,560 estimates of the Variance Ratio test of the efficiency of Asian and Australasian stock markets. We test if there is evidence of violation of the EMH and we also explain the heterogeneity in the reported test results. Our meta-regression analysis specifically accommodates the possibility of publication selection in favor of accepting the null hypothesis of market efficiency. We find that Asian stock markets are, on average, not informationally efficient. However, market efficiency has improved over time and market capitalization and economic freedom influences stock market efficiency; more developed and less regulated stock markets are more efficient.

This paper empirically examines whether the three East Asian stock markets, namely those of China, Japan and South Korea are individually and/or jointly efficient and whether the cointegrated markets have contagion from one to the other market(s). While the individual market efficiency is examined through testing for random walk hypothesis, the joint market efficiency is examined through testing for cointegration and contagion hypotheses. The study finds that the hypothesis of individual market efficiency is strongly rejected for the Chinese stock market but not for Japanese and South Korean stock markets. However, the joint market efficiency is found to be strongly rejected for all these markets under the cointegration sense. We take a simple case of contagion and find that although there is a long-term relationship among these three markets, the contagion hypothesis could not be rejected only between Japanese and South Korean stock markets indicating short-run portfolio diversification benefits from these two markets.
