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.

With the right moves, it can yieldhigh returns; one misstep, however, can have disastrousconsequences.

In The Art of Short Selling, Kathryn Staley, anexpert in the field, examines the essentials of this importantinvestment vehicle, providing a comprehensive game plan with whichyou can effectively play--and win--the short selling game. Whether used as a means of hedging bets, decreasing the volatilityof total returns, or improving returns, short selling must behandled with care--and with the right know-how. As Staley pointsout, "Short selling is not for the faint of heart. If a stock movesagainst the position holder, the effect on a portfolio and networth can be devastating. Investors need to understand the impacton their accounts as well as the consequences of getting bought inbefore they indulge in short selling." The Art of Short Sellingguides you--clearly and concisely--through the ins and outs of thishigh-risk, high-stakes game. The first--and most important--move in selling short is to identifyflaws in a business before its share prices drop.

Following the Great Financial Crisis, the S&P 500 advanced more than 17 percent annualized from February 2009 through June 2018. At this pace, a buy-and-hold investor in the stock market would see their money double in 5 years and more than triple in 7 years. This performance has lulled many investors into thinking that such above-average returns will be with us into perpetuity. Unfortunately, this may not be the case. Far more likely, the return an investor may receive from the stock market will be slightly better than half the long-term average, about 5% to 7%. Most investment portfolios hold a greater allocation to stocks than any other class of investment asset. Massive amounts of wealth were created from the bull market since early 2009 providing institutions and individuals with a rising tide that lifted their portfolios above their goals without much effort. The environment of the future stands to be far less accommodating, so finding suitable investments (other than U.S. stocks) that can achieve the necessary returns (or make up the shortfall) will be a critical component of achieving goals in years to come. This book will explore those solutions.

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.

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.
