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.

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).

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.

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.

Seminar paper from the year 2018 in the subject Economics - Finance, grade: 1, , language: English, abstract: The Efficient Market Hypothesis (EMH) theory commonly referred to as the Random Walk Theory is one of the most debated topics in finance studies over the years because of the growing concerns that investors can trade on the available information so as to make abnormal profits in the market. EMH states that the price of a security (current stock prices) in the market reflects all the available information on its fundamental value at all times, hence investors cannot make any abnormal profits above the market prices using this information. EMH explains why changes in security prices occur and how those changes happen, hence very crucial to investors as they make their investment decisions in the security market. Many investors both domestic and global invest on securities that are undervalued as they expect their value to increase in the future. Other investors including investment managers also stress that they are able to choose those securities that can outperform the market prices with the core objective of gaining more profits. EMH argues that none of these assumptions is effective because the advantage gained is less than the transaction costs incurred such as research costs on the information hence not in a position to outperform the market price of these securities

Seminar paper from the year 2011 in the subject Business economics - Investment and Finance, grade: 1,0, University of Hull, course: Current Issues Financial Management, language: English, abstract: The study examines and critical reviews the literature for the different implications based on the three levels of the Efficient Market Hypothesis for investors and company managers. If the weak form of the EMH holds, the technical analyse is useless, but ninety percent of traders in London are using it. If the semi-strong-form holds the fundamental analysis, study of published accounts, search for undervalued companies are useless and investors should be focus on diversification and avoiding of transaction costs. Furthermore the semi-strong form would imply for managers, that accounting disclosure to deceived shareholders is useless, the company market value is the best indicator for the company value and management decisions, the company does not need specialists for the timing of issues and there are no opportunities for a cheap acquisition of another company. At least if the strong-form of the EMH holds, it would imply that even with insider information it would not be possible to get above average returns. The literature shows, that the studies of EMH have made an important contribution to our understanding of the security market. It also shows that in some cases scientific results do not strong influence the behaviour of manager and investors in the "real world".
