Available in PDF, EPUB and Kindle. Book excerpt: This is the Black & White version of the book, available at a discount, which does not include the research data and analysis tables. 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).

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.

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: 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The past twenty years have seen an extraordinary growth in the use of quantitative methods in financial markets. Finance professionals now routinely use sophisticated statistical techniques in portfolio management, proprietary trading, risk management, financial consulting, and securities regulation. This graduate-level textbook is intended for PhD students, advanced MBA students, and industry professionals interested in the econometrics of financial modeling. The book covers the entire spectrum of empirical finance, including: the predictability of asset returns, tests of the Random Walk Hypothesis, the microstructure of securities markets, event analysis, the Capital Asset Pricing Model and the Arbitrage Pricing Theory, the term structure of interest rates, dynamic models of economic equilibrium, and nonlinear financial models such as ARCH, neural networks, statistical fractals, and chaos theory. Each chapter develops statistical techniques within the context of a particular financial application. This exciting new text contains a unique and accessible combination of theory and practice, bringing state-of-the-art statistical techniques to the forefront of financial applications. Each chapter also includes a discussion of recent empirical evidence, for example, the rejection of the Random Walk Hypothesis, as well as problems designed to help readers incorporate what they have read into their own applications.

Book excerpt: The efficient markets hypothesis has been the central proposition in finance for nearly thirty years. It states that securities prices in financial markets must equal fundamental values, either because all investors are rational or because arbitrage eliminates pricing anomalies. This book describes an alternative approach to the study of financial markets: behavioral finance. This approach starts with an observation that the assumptions of investor rationality and perfect arbitrage are overwhelmingly contradicted by both psychological and institutional evidence. In actual financial markets, less than fully rational investors trade against arbitrageurs whose resources are limited by risk aversion, short horizons, and agency problems. The book presents and empirically evaluates models of such inefficient markets. Behavioral finance models both explain the available financial data better than does the efficient markets hypothesis and generate new empirical predictions. These models can account for such anomalies as the superior performance of value stocks, the closed end fund puzzle, the high returns on stocks included in market indices, the persistence of stock price bubbles, and even the collapse of several well-known hedge funds in 1998. By summarizing and expanding the research in behavioral finance, the book builds a new theoretical and empirical foundation for the economic analysis of real-world markets.

Available in PDF, EPUB and Kindle. Book excerpt: For over half a century, financial experts have regarded the movements of markets as a random walk--unpredictable meanderings akin to a drunkard's unsteady gait--and this hypothesis has become a cornerstone of modern financial economics and many investment strategies. Here Andrew W. Lo and A. Craig MacKinlay put the Random Walk Hypothesis to the test. In this volume, which elegantly integrates their most important articles, Lo and MacKinlay find that markets are not completely random after all, and that predictable components do exist in recent stock and bond returns. Their book provides a state-of-the-art account of the techniques for detecting predictabilities and evaluating their statistical and economic significance, and offers a tantalizing glimpse into the financial technologies of the future. The articles track the exciting course of Lo and MacKinlay's research on the predictability of stock prices from their early work on rejecting random walks in short-horizon returns to their analysis of long-term memory in stock market prices. A particular highlight is their now-famous inquiry into the pitfalls of "data-snooping biases" that have arisen from the widespread use of the same historical databases for discovering anomalies and developing seemingly profitable investment strategies. This book invites scholars to reconsider the Random Walk Hypothesis, and, by carefully documenting the presence of predictable components in the stock market, also directs investment professionals toward superior long-term investment returns through disciplined active investment management.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Asset pricing theory yields deep insights into crucial market phenomena such as stock market bubbles. Now in a newly revised and updated edition, this textbook guides the reader through this theory and its applications to markets. The new edition features new results on state dependent preferences, a characterization of market efficiency and a more general presentation of multiple-factor models using only the assumptions of no arbitrage and no dominance. Taking an innovative approach based on martingales, the book presents advanced techniques of mathematical finance in a business and economics context, covering a range of relevant topics such as derivatives pricing and hedging, systematic risk, portfolio optimization, market efficiency, and equilibrium pricing models. For applications to high dimensional statistics and machine learning, new multi-factor models are given. This new edition integrates suicide trading strategies into the understanding of asset price bubbles, greatly enriching the overall presentation and further strengthening the book’s underlying theme of economic bubbles. Written by a leading expert in risk management, Continuous-Time Asset Pricing Theory is the first textbook on asset pricing theory with a martingale approach. Based on the author’s extensive teaching and research experience on the topic, it is particularly well suited for graduate students in business and economics with a strong mathematical background.

Download or read book Testing the Efficient Market Hypothesis at the Semi Strong Level in Palestine Stock Exchange - Event Study of the Mandatory Disclosure written by Hussein Salameh and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: It is common to distinguish among three versions of the Efficient Market Hypothesis EMH: the weak; the semi-strong; and the strong forms of the hypothesis. These versions differ by their notions of what is meant by the term "all available information". The Semi-Strong form hypothesis states that all publicly available information regarding the prospects of a firm must be already reflected in the stock price. The type of test conducted in this version is Event Study. We perform an event study to test the efficiency of the market hypothesis at the semi strong level for Palestine Stock Exchange, to realize the effect of the mandatory disclosure on stock prices. The results show that we can reject the null hypothesis that there is no difference between the average abnormal return and zero which indicates that the market is inefficient at the semi strong level and that the information are gradually reflected on the stock prices.
