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.
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.
Download or read book The Efficient Market Hypothesis and Its Application to Stock Markets written by Sebastian Harder and published by GRIN Verlag. 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).

This book was released on 2017-05-09 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2015 in the subject Economics - Finance, grade: 2:1 (68%), Northumbria University, course: Business with Financial Management, language: English, abstract: Virtual and computer games are rapidly increasing with the introduction of the smartphone and the app stores across multiple platforms and devices with an increase in games with virtual economies. This dissertation will analyse the efficient market hypothesis, along with commonly known anomalies and information announcements. It will find out whether there are market inefficiencies in virtual games in the form of anomalies, more specifically the intra-day effect. The intra-day effect anomaly is one of many critiques of the efficient market hypothesis and there have been many studies conducted into the intra-day effect. Most research on the intra-day effect anomaly is concerning real world markets and the results have contradicted one another. This study looks at the price change movements of 118 randomly quota sampled player cards within the market of FIFA Ultimate Team. Statistical analysis in the form of mean, standard deviation, and coefficients of variances tests were carried out to identify if there were any market anomalies and reactions to information announcements. A strong correlation between market inefficiencies, anomalies, and information announcements had been discovered within the research of the virtual market in FIFA Ultimate Team. The study actually found that because of an information announcement overreaction and an intra-day effect, at a specific time during a Wednesday, a player could sell their card for potentially 233% more than what they could have an hour earlier. This research study in turn supports that market anomalies do exist in games but it was also discovered that the market is semi-strong form efficient in its reaction post-information announcement.

Available in PDF, EPUB and Kindle. 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.

Download or read book Investing in a market where people believe in efficiency is like playing bridge with someone who has been told it doesn t do any good to look at the cards written by Charles Ekweruo and published by GRIN Verlag. This book was released on 2011-12-08 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essay from the year 2011 in the subject Business economics - Investment and Finance, grade: 1, University of Bradford (School of Management-Business School), course: Capital Market Investment And Finance, language: English, abstract: “In an efficient market, security (example shares) prices rationally reflect available information” (Arnold 2005, p.684). The efficient market hypothesis (EMH) refers to share price movement with respect to available information and thus no trader will be presented with an opportunity of making supernormal profits (except by chance), therefore their profits on a share will reflect the riskiness associated with that shares (Pike and Neal 2009). However, “detailed investigations using advanced econometric techniques, larger data sets, increasingly powerful computing ability, and alternative theoretical models have in the last few years revealed a range of anomalies when the unpredictability-of -returns hypothesis is tested. Financial markets are often predictable to some extent, but the crucial question is whether this predictability can be exploited to make excess profits from trading in the markets‖ (Mills 1992, as cited by Coutts, 2000, p.579). Warren Buffet, known as one of the most successful investors in history, is convinced that stock markets are inefficient. ''I think it's fascinating how the ruling orthodoxy can cause a lot of people to think the earth is flat. Investing in a market where people believe in efficiency is like playing bridge with someone who has been told it doesn't do any good to look at the cards'' (Buffet, 1984, as cited by Davis, 1990, p.4). Buffet is referring to the fact that market price movements are often caused by emotional purchases and sales of stocks, resulting to an inefficient market, in other words, irrational market prices (Buffet, 1984). However, there are financial economists who see it the other way round. They agree with the “Efficient Market Hypothesis” which states that security prices rationally reflect only available information (Arnold, 2005, p. 684) (see fig 1) therefore inhibiting the possibility of beating the market. According to this theory, there does not exist under- or overvalued shares, only true and fair values. It is difficult to say which side is right and which side is wrong, as both are based on logical reasoning and transparent facts. This paper will therefore, evaluate both concepts using different theories and ideas from those for and those against the EMH in order to find a conclusion which is reasonable and flexible enough to support a constructive point of view (based on pragmatism) and to better understand if Buffet‟s statement is true or false or maybe both.

Download or read book Adaptive Markets written by Andrew W. Lo and published by Princeton University Press. This book was released on 2019-05-14 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new, evolutionary explanation of markets and investor behavior Half of all Americans have money in the stock market, yet economists can’t agree on whether investors and markets are rational and efficient, as modern financial theory assumes, or irrational and inefficient, as behavioral economists believe. The debate is one of the biggest in economics, and the value or futility of investment management and financial regulation hangs on the answer. In this groundbreaking book, Andrew Lo transforms the debate with a powerful new framework in which rationality and irrationality coexist—the Adaptive Markets Hypothesis. Drawing on psychology, evolutionary biology, neuroscience, artificial intelligence, and other fields, Adaptive Markets shows that the theory of market efficiency is incomplete. When markets are unstable, investors react instinctively, creating inefficiencies for others to exploit. Lo’s new paradigm explains how financial evolution shapes behavior and markets at the speed of thought—a fact revealed by swings between stability and crisis, profit and loss, and innovation and regulation. An ambitious new answer to fundamental questions about economics and investing, Adaptive Markets is essential reading for anyone who wants to understand how markets really work.
Download or read book A Non Random Walk Down Wall Street written by Andrew W. Lo and published by Princeton University Press. This book was released on 2011-11-14 with total page 449 pages. 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.
