There is also a Full Colour version that includes all the research data and analysis tables. What is a Stock Market? How do stock markets operate? Who invests in a stock market and when is it an appropriate tool for investment? Why do we care if a stock market is efficient or not? Where can we find evidence of market efficiency? With what tools can we test market efficiency?These are some of the questions that this book approaches. The Efficient Market Hypothesis (EMH) is a theory in financial economics, developed by Eugene Fama, which states that asset prices fully reflect all available information. Thus, it is implied that stocks always trade at their fair value, making it impossible for investors to "beat the market" via technical or fundamental analysis, since market prices should only react to new information.There are three variants of the EMH: "weak," "semi-strong," and "strong" form. The weak form of the EMH claims that prices already reflect all past publicly available market information. The semi-strong form claims that prices reflect all publicly available information, thus price changes occur to reflect new publicly available information. The strong form adds to this that prices instantly reflect even hidden private "insider" information.Testing the EMH is no easy task: Quantifying the availability of information and its effect on prices and market efficiency is challenging, making research on the subject difficult, time consuming and open to criticism. However, anecdotal evidence suggests that markets at best reach semi-strong form efficiency, with weak form efficiency being the norm. However, even this is challenged by the critics of EMH, via concepts such as Behavioural Finance.This book aims to familiarise the reader with the concept of EMH, covering the fundamentals and relevant literature. We then discuss market efficiency tests for Weak Form Market Efficiency, examining in more detail the day-of-the-week effect and its significance on stock market efficiency. The day-of-the-week effect is defined as a pattern where a certain day of the week has abnormal returns continuously. It is an anomaly that violates the random walk hypothesis, and thus implies that a market is not Weak Form efficient.We put theory into practice through the Empirical Research section which is divided into two parts, looking at two different approaches to researching the day-of-the-week effect, via the examination of actual research examples on a small European stock exchange. Both of these Thesis tested the hypothesis of random walk to determine the authenticity of weak form market efficiency for a small emerging stock market within the EU (the Cyprus Stock Exchange).

Book excerpt: Seminar paper from the year 2009 in the subject Business economics - Investment and Finance, grade: 2,3, University of Edinburgh, language: English, abstract: While using standard tests of weak form market efficiency along with the more recent DELAY test, this report examines if the returns of six selected stocks and two decile indices follow a random walk which would evidence the non-predictability of future stock returns by historical prices which is a necessary condition for the weakest form of market efficiency. The evidence of four different measurement tests suggests that except of one stock all stocks and indices drift away from the weak form market efficiency hypothesis.

Book excerpt: Stock market efficiency is one of the important concept in capital markets to understand flow of working in capital markets. With the greater movement in investments across the international boarders owing to integration of economies of the world, knowledge about the efficiency of developing markets is also obtaining greater importance. This study tested the hypothesis of random walk to determine the authenticity of the weak form market efficiency for the emerging and the biggest stock market of Pakistan named "Karachi Stock Exchange."

Available in PDF, EPUB and Kindle. Book excerpt: The efficient market hypothesis (EMH) suggests that stock prices fully reflect all available information in the market and no investor is able to earn excess return on the basis of some secretly held private, public or historical information. Efficient market hypothesis (EMH) can be further divided into three sub hypotheses depending upon the information set involved and these are weak form efficient market hypothesis, semi strong form efficient market hypothesis and strong form efficient market hypothesis. This research has examined the weak form of efficient market hypothesis on the four major stock exchanges of South Asia that are Karachi stock exchange (KSE-100), Bombay stock exchange (BSE-SENSEX), Colombo stock exchange (CSE-MPI) and Dhaka stock exchange (DSE-GEN). Historical index values of KSE-100, BSE-SENSEX, CSE-MPI and DSE-GEN on a monthly, weekly and daily basis for a period of 14 Years (July 1997 to June 2011). We applied four different statistical tests including runs test, serial correlation (Durbin Watson test), unit root and variance ratio test. Findings suggest that none of the four major stock markets of south-Asia follows Random-walk and hence all these markets are not the weak form of efficient market.

Book excerpt: Research Paper (undergraduate) from the year 2008 in the subject Business economics - Investment and Finance, grade: 1.7, The FOM University of Applied Sciences, Hamburg, language: English, abstract: Especially after the 90ies, where the stock markets raised enormously, many private investors joined the stock market and were blended by abnormal profits and neglected possible losses. The same behavior could be observed before the Financial Crisis became reality. But each endless raising stock market would finally collapse, because stock prices are randomly and only driven by relevant news. The adjustment to the news is quickly. This is the theoretical argumentation of the Efficient Market Hypothesis (EMH), which will be evaluated in this paper. The author gives an overview about the EMH by explaining the basic principles and its mathematical formulation. The practical part evaluated the EMH on selected examples, where the theory could only be partly approved.

Book excerpt: Seminar paper from the year 2018 in the subject Business economics - Market research, grade: 1,0, accadis Hochschule Bad Homburg, course: International Finance, language: English, abstract: This project will focus on the Efficient Market Hypothesis which is used in the form of its abbreviation EMH during the next sections. In this context, in Part A EMH will be examined in the context of the Dow Jones Industrial Average, which includes 30 components and is America's most prominent and globally applied stock index. Multiple economists have taken studies of efficient market hypothesis to their main subject, subsequently, efficient market hypothesis is one of the most common and observed theories in modern finance. Today, EMH is widely used and prospers from frequent testing, which, in the past, has led to new findings, more precisely, different emphasis of EMH. During his research, the previously mentioned economist Fama investigated in his test that there must be three emphasis of EMH, which he differentiated into weak form market efficiency, semi-strong form market efficiency as well as strong form market efficiency. In the modern theory of finance, the most known starting theory is that of efficient capital markets. In repetition to part A of this assignment, the term “efficiency” denotes the fact that investors have no opportunity of obtaining abnormal profits from capital market transactions as compared to other investors, so that they cannot beat the market. Consequently, investors are forced to invest in higher risk assets to increase the probability of gaining short term profits. The EMH theory is very controversial and many opposing opinions regarding this theory exist. By empirically testing, this assignment outlines the insufficiency to reject Weak Form Market Efficiency for the Dow Jones Industrial Average index. However, stock market returns are considered to be random. It is suggested that investors are incapable of constantly outperforming the market even if stock market indexes show certain temporarily anomalies, which remain hypothesized. Besides of other studies and reports, this assignment emphasizes the inability of the Efficient Market Hypothesis to explain anomalies at the current state of research. Finally, further research on the basis of new empirical data will maintain the debates about interpretation and possibilities to forecast stock prices in the course of EMH.

Book excerpt: As per definition of efficient market hypothesis (EMH), there is a need that stock prices should reflect all available information in the market and no investor is able to earn excess return on the basis of some secretly held private, public or historical information. Efficient market hypothesis (EMH) can be further divided into three sub hypotheses depending upon the information set involved and these are weak form efficient market hypothesis, semi strong form efficient market hypothesis and strong form efficient market hypothesis. This study has examined the weak form of efficiency on the six major stock exchanges that are present in North-America and Europe including NYSE Composite (USA), S&P TSX Composite (Canada), FTSE 100 Index (UK), CAC 40 (France), DAX 30 (Germany) and IBEX 35 (Spain). Historical index values are gathered on a monthly, weekly and daily basis for a period of 14 Years (July 1997 to June 2011). Two statistical tests including runs test, and variance ratio test were applied for analysis and results. It is found in the process that two out of six developed stock markets of North-America and Europe doesn't follow Random-walk and hence NYSE Composite, S&P TSX Composite, DAX 30 (Germany) and IBEX 35 (Spain) are the weak form of efficient markets.

Available in PDF, EPUB and Kindle. Book excerpt: This empirical study is conducted to test the weak-form market efficiency of the stock market returns of Pakistan, India, Sri Lanka, China, Korea, Hong Kong, Indonesia, Malaysia, Philippine, Singapore, Thailand, Taiwan, Japan and Australia. Monthly observations are taken for the period January 2004 to December 2009. Autocorrelation, Ljung-Box Q-statistic Test, Runs Test, Unit Root Test and the Variance Ratio are used to test the hypothesis that the stock market follows a random walk. Monthly returns are not normally distributed, because they are negatively skewed and leptokurtic. In aggregate we concluded that the monthly prices do not follows random walks in all the countries of the Asian-Pacific region. The investors can take the stream of benefits through arbitrage process from profitable opportunities across these markets.

Book excerpt: Ever Since Fama (1965) presented his Efficient Market hypothesis, a lot of research has been done to test its authenticity; developed as well as emerging economies are used to validate the theory. The results are conflicting and the change in the current market circumstances persuaded the researcher to investigate the Gulf Stock Markets. Data of six Stock Exchanges in Gulf for the period of five years is taken. Daily closing stock indices of Oman, UAE, Kuwait, Saudi Arabia, Bahrain and Qatar are taken from 1st January 2011 to 31 December 2015, Auto correlation and runs test were used to test the Weak Form Market Efficiency. The results of the Parametric Tests (Both Auto Correlation and Runs test) provide evidence that the Stock prices in all the Gulf Markets are not following the random walk model and the significant auto correlation co-efficient at different lags has rejected the null hypothesis of Weak Form Efficiency.
Download or read book The Efficient Market Theory and Evidence written by Andrew Ang and published by Now Publishers Inc. This book was released on 2011 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
