Available in PDF, EPUB and Kindle. Book excerpt: The Ascent of Market Efficiency weaves together historical narrative and quantitative bibliometric data to detail the path financial economists took in order to form one of the central theories of financial economics—the influential efficient-market hypothesis—which states that the behavior of financial markets is unpredictable. As the notorious quip goes, a blindfolded monkey would do better than a group of experts in selecting a portfolio of securities, simply by throwing darts at the financial pages of a newspaper. How did such a hypothesis come to be so influential in the field of financial economics? How did financial economists turn a lack of evidence about systematic patterns in the behavior of financial markets into a foundational approach to the study of finance? Each chapter in Simone Polillo's fascinating meld of economics, science, and sociology focuses on these questions, as well as on collaborative academic networks, and on the values and affects that kept the networks together as they struggled to define what the new field of financial economics should be about. In doing so, he introduces a new dimension—data analysis—to our understanding of the ways knowledge advances. There are patterns in the ways knowledge is produced, and The Ascent of Market Efficiency helps us make sense of these patterns by providing a general framework that can be applied equally to other social and human sciences.
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 Stock Market Efficiency Insider Dealing and Market Abuse written by Mr Paul Barnes and published by Gower Publishing, Ltd.. This book was released on 2012-09-28 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent turbulence in the stock market has brought into question the way, and prices at which, shares are traded, and how the market effectively values companies. It has also raised public concern as to the way by which dealers and investors take advantage of changes in market prices. A number of high profile criminal prosecutions of insider dealing and market abuse and the frequent claims of other instances, combined with the changes in regulations resulting in a more aggressive and proactive stance by the various regulators, have brought the issue under the spotlight. This book discusses what makes stock market efficiency so important for the economy, looks at the theory and issues that underpin market abuse and why an offence often dismissed as a victimless crime is punished so severely. It explores the impact of perception and other factors that distort the market and outlines the extent of abuse. Regulators, lawyers, company officials, investigators, professional advisers and of course investors, both professional and otherwise will find this a helpful guide to the underlying elements of fraud and market manipulation.

Download or read book Inefficient Markets written by Andrei Shleifer and published by OUP Oxford. This book was released on 2000-03-09 with total page 225 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Beyond the Market written by Jens Beckert and published by Princeton University Press. This book was released on 2009-01-10 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beyond the Market launches a sociological investigation into economic efficiency. Prevailing economic theory, which explains efficiency using formalized rational choice models, often simplifies human behavior to the point of distortion. Jens Beckert finds such theory to be particularly weak in explaining such crucial forms of economic behavior as cooperation, innovation, and action under conditions of uncertainty--phenomena he identifies as the proper starting point for a sociology of economic action. Beckert levels an enlightened critique at neoclassical economics, arguing that understanding efficiency requires looking well beyond the market to the social, cultural, political, and cognitive factors that influence the coordination of economic action. Beckert searches social theory for the components of an alternative theory of action, one that accounts for the social embedding of economic behavior. In Durkheim and Parsons he finds especially useful approaches to cooperation; in Luhmann, a way to understand how people act under highly contingent conditions; and in Giddens, an understanding of creative action and innovation. Together, these provide building blocks for a research program that will yield a theoretically sophisticated understanding of how economic processes are coordinated and the ways that markets are embedded in social, cultural, and cognitive structures. Containing one of the most fully informed critiques of the neoclassical analysis of economic efficiency--as well as one of the most thoughtful blueprints for economic sociology--this book reclaims for sociology the study of one of the most important arenas of human action.

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 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.
Download or read book Efficient Market Hypothesis written by Mario Chinas and published by Library of Cyprus. This book was released on 2019-02-23 with total page 114 pages. 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 Financial Markets Theory written by Emilio Barucci and published by Springer. This book was released on 2017-06-08 with total page 843 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work, now in a thoroughly revised second edition, presents the economic foundations of financial markets theory from a mathematically rigorous standpoint and offers a self-contained critical discussion based on empirical results. It is the only textbook on the subject to include more than two hundred exercises, with detailed solutions to selected exercises. Financial Markets Theory covers classical asset pricing theory in great detail, including utility theory, equilibrium theory, portfolio selection, mean-variance portfolio theory, CAPM, CCAPM, APT, and the Modigliani-Miller theorem. Starting from an analysis of the empirical evidence on the theory, the authors provide a discussion of the relevant literature, pointing out the main advances in classical asset pricing theory and the new approaches designed to address asset pricing puzzles and open problems (e.g., behavioral finance). Later chapters in the book contain more advanced material, including on the role of information in financial markets, non-classical preferences, noise traders and market microstructure. This textbook is aimed at graduate students in mathematical finance and financial economics, but also serves as a useful reference for practitioners working in insurance, banking, investment funds and financial consultancy. Introducing necessary tools from microeconomic theory, this book is highly accessible and completely self-contained. Advance praise for the second edition: "Financial Markets Theory is comprehensive, rigorous, and yet highly accessible. With their second edition, Barucci and Fontana have set an even higher standard!"Darrell Duffie, Dean Witter Distinguished Professor of Finance, Graduate School of Business, Stanford University "This comprehensive book is a great self-contained source for studying most major theoretical aspects of financial economics. What makes the book particularly useful is that it provides a lot of intuition, detailed discussions of empirical implications, a very thorough survey of the related literature, and many completely solved exercises. The second edition covers more ground and provides many more proofs, and it will be a handy addition to the library of every student or researcher in the field."Jaksa Cvitanic, Richard N. Merkin Professor of Mathematical Finance, Caltech "The second edition of Financial Markets Theory by Barucci and Fontana is a superb achievement that knits together all aspects of modern finance theory, including financial markets microstructure, in a consistent and self-contained framework. Many exercises, together with their detailed solutions, make this book indispensable for serious students in finance."Michel Crouhy, Head of Research and Development, NATIXIS
