Efficiency and Anomalies in Stock Markets


Book Description

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.




Capital Market Efficiency and Stock Price Anomalies


Book Description

The efficient market hypothesis (EMH), well known as the random walk theory, proposes that stock prices should fully, immediately, reflect all available relevant information about the value of the firm. The concept of capital market efficiency is central to finance. If the efficient market hypothesis holds, the stock prices should fully reflect all relevant information about the firm value. As a consequence, investors cannot expect to achieve excess returns from their investment strategies. While the idea market efficiency offers an important implication to investors, studies show that the efficient market theory has been challenged. Various anomalies have been documented in the last two decades that contradicts to the efficient market hypothesis. This study reviews the theory and evidence of market efficiency and particularly it investigates a number of anomalies including PE ratio, Price-to-book ratio and firm size effects in Australia.

Information Efficiency and Anomalies in Asian Equity Markets


Book Description

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 Handbook of Equity Market Anomalies


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.




Capital Market Anomalies: Explained by Human ?s Irrationality


Book Description

Why do small caps achieve higher risk-adjusted yields than large caps? Why do stock prices increase or decrease upon an index entry respectively deletion? Why does January records higher yields than the remaining months of the year? These as well as other observed capital market anomalies or phenomena could be insufficiently explained by the classical capital market theory, which proceeds on the assumptions that all correspondent information are reflected in the stock prices, all negative effects are directly balanced on the market level and that efficiency of arbitrage principle exists as well as that all market participants act rationally (i.e. optimizing their benefits in the sense of the homo economicus). This motivated some economists and psychologists to include behavioural scientific findings in their research of the influences on the formation of prices on the capital market. In the 1980s the theory of Behavioural Finance was developed, which challenges the homo economicus. Researchers came to the conclusion that humans are not only acting rational, but that they are also influenced by emotions, knowledge and experiences. This new scientific behavioural oriented theory, which is today a separate branch of research, contradicts the classical capital market theory and supplies explanations for the observed phenomena on the capital market. The aim of this book is to demonstrate how human behaviour influences the development on the capital market and how Behavioural Finance serves as an explanation for the empirically observed capital market anomalies. This book begins with the introduction of the theoretical basis of Behavioural Finance and its emergence; tasks as well as aims will be explained in detail. Subsequently, human's heuristics as well as anomalies and irrationalities in their decision making process will be demonstrated. In the third chapter, the capital market anomalies or phenomena as well as the irrational and behavioural reasons for their existen




The Market Anomaly "Size Effect". Literature Review, Key Theories and Empirical Methods


Book Description

Essay from the year 2014 in the subject Business economics - Business Management, Corporate Governance, grade: 16 (1,7), University of St Andrews (School of Management), course: Research Methods for Finance and Management, language: English, abstract: The size effect is a market anomaly in asset pricing according to the market efficiency theory. According to the current body of research, market anomalies arise either because of inefficiencies in the market or the underlying pricing model must be flawed. Anomalies in the financial markets are typically discovered form empirical tests. These tests usually rely jointly on one null hypothesis H0= markets are efficient AND they perform according to a specified equilibrium model (usually CAPM). Thus, if the empirical study rejects the H0, the reason could either be due to market inefficiency or due to the incorrect model. Market efficiency theory says that the price of an asset fully reflects all current information and is not predictable (Fama 1970). Fama (1997) states that market anomalies, even long‐term anomalies, are not an indicator for market inefficiencies due to the reason that they randomly split between “underreaction and overreaction, (so) they are consistent with market efficiency” (p. 284), they happen by chance and it is always possible to beat the market by chance. This essay will give an overview of the literature of the size effect and will stress the key theories, empirical methods and findings, as well as the existing body of research about this particular anomaly.
