This book was released on 2010-11 with total page 65 pages. Available in PDF, EPUB and Kindle. 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: 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).

Download or read book Testing Market Efficiency written by Saqib Nisar and published by . This book was released on 2014 with total page 33 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2013-04-10 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research Paper (undergraduate) from the year 2012 in the subject Business economics - Investment and Finance, grade: 89%, University of Greenwich (Business), course: Finance, language: English, abstract: It can be assumed that the internet was one of the most influential inventions of the 20th century. The internet opened up completely new ways of communicating and executing businesses. It enabled shopping portals like Amazon or eBay to emerge and revolutionise the shopping experience of millions of customers worldwide. The new economy was a Symbol for seemingly endless possibilities and a market with no limits. However, all those new ways of doing business could not prevent one of the biggest stock market crashes in modern history caused by the dot.com bubble. This essay examines if the dot.com bubble stands in contradiction to the efficient market hypothesis (EMH) and their underlying assumptions. It will be argued that in the short term the efficient market can be bypassed but it will regulate itself again in the long run. The second part describes the strategy of a successful initial public offering (IPO) and analyses if the EMH has an impact on this endeavour. This paper will claim that the EMH influences the pricing of stocks and that a long term strategy is a key for a successful IPO.

Available in PDF, EPUB and Kindle. Book excerpt: Data sharing can accelerate new discoveries by avoiding duplicative trials, stimulating new ideas for research, and enabling the maximal scientific knowledge and benefits to be gained from the efforts of clinical trial participants and investigators. At the same time, sharing clinical trial data presents risks, burdens, and challenges. These include the need to protect the privacy and honor the consent of clinical trial participants; safeguard the legitimate economic interests of sponsors; and guard against invalid secondary analyses, which could undermine trust in clinical trials or otherwise harm public health. Sharing Clinical Trial Data presents activities and strategies for the responsible sharing of clinical trial data. With the goal of increasing scientific knowledge to lead to better therapies for patients, this book identifies guiding principles and makes recommendations to maximize the benefits and minimize risks. This report offers guidance on the types of clinical trial data available at different points in the process, the points in the process at which each type of data should be shared, methods for sharing data, what groups should have access to data, and future knowledge and infrastructure needs. Responsible sharing of clinical trial data will allow other investigators to replicate published findings and carry out additional analyses, strengthen the evidence base for regulatory and clinical decisions, and increase the scientific knowledge gained from investments by the funders of clinical trials. The recommendations of Sharing Clinical Trial Data will be useful both now and well into the future as improved sharing of data leads to a stronger evidence base for treatment. This book will be of interest to stakeholders across the spectrum of research-from funders, to researchers, to journals, to physicians, and ultimately, to patients.

Book excerpt: Alphanomics: The Informational Underpinnings of Market Efficiency is intended to be a compact introduction to academic research on market efficiency, behavioral finance, and fundamental analysis and is dedicated to the kind of decision-driven and prospectively-focused research that is much needed in a market constantly seeking to become more efficient. The authors refer to this type of research as Alphanomics, the informational economics behind market efficiency. Alpha refers to the abnormal returns, which provide the incentive for some subpopulation of investors to engage in information acquisition and costly arbitrage activities. Nomics refers to the economics of alpha extraction, which encompasses the costs and incentives of informational arbitrage as a sustainable business proposition. Some of the questions that are addressed include: why do we believe markets are efficient?; what problems have this belief engendered?; what factors can impede and/or facilitate market efficiency?; what roles do investor sentiment and costly arbitrage play in determining an equilibrium level of informational efficiency?; what is the essence of value investing?; how is it related to fundamental analysis (the study of historical financial data)?; and how might we distinguish between risk and mispricing based explanations for predictability patterns in returns? The first two sections review the evolution of academic thinking on market efficiency and introduce the noise trader model as a rational alternative. Section 3 surveys the literature on investor sentiment and its role as a source of both risks and returns. Section 4 discusses the role of fundamental analysis in value investing. Section 5 reviews the literature on limits to arbitrage, and section 6 discusses research methodology issues associated with the need to distinguish mispricing from risk.

Book excerpt: The form of ‘reflexivity’ – defined by the dictionary as that which is ‘directed back upon itself’ – that is most relevant to economic methodology is that where observation of the economy leads to ideas that change behavior, which in turn changes (is directed back upon) the economy itself. As George Soros explains: "if investors believe that markets are efficient then that belief will change the way they invest, and that in turn will change the nature of the markets they are observing ... That is the principle of reflexivity". Although various versions of reflexivity have long been discussed, in recent years George Soros has been particularly effective in bringing ideas about reflexivity to the attention of the economic and financial communities. In a series of writings he has systematically argued that reflexivity is not only an important aspect of economic life, it is an aspect that is neglected in most mainstream theorizing; and in addition, that the neglect of reflexivity has been responsible for the failure of economists to predict, explain, or offer a solution for events such as the recent financial crisis. Soros’ ideas about reflexivity have important methodological significance, and his chapter in this book summarizes and clarifies his arguments. His contribution is joined by those of thirteen scholars from a wide range of relevant fields, who provide a commentary on the idea of reflexivity in economics. This book was originally published as a special issue of The Journal of Economic Methodology.

Available in PDF, EPUB and Kindle. Book excerpt: Learn how to profit from information about insider trading. The term insider trading refers to the stock transactions of the officers, directors, and large shareholders of a firm. Many investors believe that corporate insiders, informed about their firms' prospects, buy and sell their own firm's stock at favorable times, reaping significant profits. Given the extra costs and risks of an active trading strategy, the key question for stock market investors is whether the publicly available insider-trading information can help them to outperform a simple passive index fund. Basing his insights on an exhaustive data set that captures information on all reported insider trading in all publicly held firms over the past twenty-one years—over one million transactions!—H. Nejat Seyhun shows how investors can use insider information to their advantage. He documents the magnitude and duration of the stock price movements following insider trading, determinants of insiders' profits, and the risks associated with imitating insider trading. He looks at the likely performance of individual firms and of the overall stock market, and compares the value of what one can learn from insider trading with commonly used measures of value such as price-earnings ratio, book-to-market ratio, and dividend yield.
