An empirical study of efficient market hypothesis and its existence in virtual markets


Book Description

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.




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.




The Efficient Market Theory and Evidence


Book Description

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.

Inefficient Markets


Book Description

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.




The Oxford Handbook of Financial Regulation


Book Description

The financial system and its regulation have undergone exponential growth and dramatic reform over the last thirty years. This period has witnessed major developments in the nature and intensity of financial markets, as well as repeated cycles of regulatory reform and development, often linked to crisis conditions. The recent financial crisis has led to unparalleled interest in financial regulation from policymakers, economists, legal practitioners, and the academic community, and has prompted large-scale regulatory reform. The Oxford Handbook of Financial Regulation is the first comprehensive, authoritative, and state of the art account of the nature of financial regulation. Written by an international team of leading scholars in the field, it takes a contextual and comparative approach to examine scholarly, policy, and regulatory developments in the past three decades. The first three parts of the Handbook address the underpinning horizontal themes which arise in financial regulation: financial systems and regulation; the organization of financial system regulation, including regional examples from the EU and the US; and the delivery of outcomes and regulatory techniques. The final three Parts address the perennial objectives of financial regulation, widely regarded as the anchors of financial regulation internationally: financial stability, market efficiency, integrity, and transparency; and consumer protection. The Oxford Handbook of Financial Regulation is an invaluable resource for scholars and students of financial regulation, economists, policy-makers and regulators.




Empirical Market Microstructure


Book Description

The interactions that occur in securities markets are among the fastest, most information intensive, and most highly strategic of all economic phenomena. This book is about the institutions that have evolved to handle our trading needs, the economic forces that guide our strategies, and statistical methods of using and interpreting the vast amount of information that these markets produce. The book includes numerous exercises.







An Engine, Not a Camera


Book Description

In An Engine, Not a Camera, Donald MacKenzie argues that the emergence of modern economic theories of finance affected financial markets in fundamental ways. These new, Nobel Prize-winning theories, based on elegant mathematical models of markets, were not simply external analyses but intrinsic parts of economic processes. Paraphrasing Milton Friedman, MacKenzie says that economic models are an engine of inquiry rather than a camera to reproduce empirical facts. More than that, the emergence of an authoritative theory of financial markets altered those markets fundamentally. For example, in 1970, there was almost no trading in financial derivatives such as "futures." By June of 2004, derivatives contracts totaling $273 trillion were outstanding worldwide. MacKenzie suggests that this growth could never have happened without the development of theories that gave derivatives legitimacy and explained their complexities. MacKenzie examines the role played by finance theory in the two most serious crises to hit the world's financial markets in recent years: the stock market crash of 1987 and the market turmoil that engulfed the hedge fund Long-Term Capital Management in 1998. He also looks at finance theory that is somewhat beyond the mainstream—chaos theorist Benoit Mandelbrot's model of "wild" randomness. MacKenzie's pioneering work in the social studies of finance will interest anyone who wants to understand how America's financial markets have grown into their current form.




The Winner's Curse


Book Description

Winner of the Nobel Memorial Prize in Economic Sciences Richard Thaler challenges the received economic wisdom by revealing many of the paradoxes that abound even in the most painstakingly constructed transactions. He presents literate, challenging, and often funny examples of such anomalies as why the winners at auctions are often the real losers—they pay too much and suffer the "winner's curse"—why gamblers bet on long shots at the end of a losing day, why shoppers will save on one appliance only to pass up the identical savings on another, and why sports fans who wouldn't pay more than $200 for a Super Bowl ticket wouldn't sell one they own for less than $400. He also demonstrates that markets do not always operate with the traplike efficiency we impute to them.
