Critical Review about implications of the Efficient Market Hypothesis


Book Description

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”.




Adaptive Markets


Book Description

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.

Critical analysis of the behavioural finance as a theory


Book Description

Seminar paper from the year 2015 in the subject Economics - Finance, grade: 1,3, University of Applied Sciences Essen, language: English, abstract: The process of making decisions on the financial market is influenced by various factors and involves a relatively complex behaviour. In general two factors drive the process, one the financial model, that represents the correlation of risk and return and second the internal factors determined by skill level, investment portfolio and education. This work at hand distinguishes between traditional and modern theory of financial markets. The Efficient Market Hypothesis (EMH) explains that investors act rationally and make economic decisions on a rational basis. These process of decision making is explained in the Expected Utility Theory and assumes that investors are doing everything to optimize their performances, which correlates with the term `homo oeconomicus`. The behavioural financial theory, taken as the modern theory, basically handles individual circumstances that result in decision makings on the market. This work at hand will work out the changes that proceeded over the years and try to explain which way is more sufficient for analysing and understanding occasions on the financial market. The aim is to impart, how behavioural finance tries to explain the financial market with help of models. Furthermore possible shortcoming or critics of these models shall be shown.




Efficiency and Anomalies in Stock Markets


Book Description

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.




Transparency and Information Asymmetry in Financial Markets


Book Description

In Financial Transparency & Information Asymmetry: A critical perspective of EU disclosure regime, Daniel Bar Aharon offers an interdisciplinary critical analysis addressing the inherent limitations mandated disclosure have on market discipline.




"Money, financial stability and efficiency". A summary of the article by Franklin Allen, Elena Carletti and Douglas Gale (2014)


Book Description

Seminar paper from the year 2016 in the subject Economics - Macro-economics, general, grade: 2,0, University of Cologne, course: Seminar Macroeconomics, language: English, abstract: At least since the start of the last financial crisis in 2007, the analysis of financial stability is a broadly investigated field of research. Macroeconomic as well as microeconomic models try to evaluate the effects of distortions (liquidity shocks, substantial losses on equity good markets. . . ) on the financial markets to the stability of all or some areas of the economy. Macroeconomic models mainly evaluate the impacts of such disruptions to benchmarks like GDP, unemployment or international trade and give recommendations regarding how institutions (central banks, governments. . . ) should react. As Blaug indicates, classical, neoclassical and new-classical models can be distinguished in this context. In contrary, microeconomic models are trying to quantify the welfare effects of such events on the level of individual economic participants like households, firms or banks. Most of this literature measure such losses via real-term variables, for example real wages or real consumption. Within such models, this causes instability on the banking/financial sector due to crashes in equity or bank-runs. Just a small group of younger literature, such as Carletti et al. (2009) or Gersbach (2012), examines the question whether modeling nominal but non-contingent contracts instead of real ones improve financial stability in theory. Among this literature, the present article “Money, financial stability and efficiency”, written by Franklin et al. (2014), can be found. The authors consider a standard banking model with aggregate return risk, aggregate liquidity risk and idiosyncratic liquidity shocks. The aim of this term paper is to briefly describe relevant model specifications and main assumptions of the underlying model. Secondly, main findings and their implications regarding the proposed research question will be presented. Finally, this term paper will complete with some critical reflections about the applicability of the model in theoretic and empirical research.
