...pricing in financial markets Efficient market hypothesis (EMH) is a theory that emerged in the 1960s. It states that it is difficult to predict the market since the price has been set and reflect the current market conditions. It is a disputed and controversial theory. The theory is comparable to other theories of pricing in financial markets. Several strengths and shortcomings emerge through comparison with other theories of pricing (Blinder, et al., 2012). EMH states that no stock is a better buy when compared to others. It is the conclusion that leads to random choices. It is a vital tenet of finance theory. The EMH theory has a basis in other finance theories. It follows the classical theory of asset prices. To determine the connection, a situation where stocks are considered based on good deals. According to the EMH theory, these stocks are worth more than their relative prices. The worth of a stock is the present value of the expected dividends. In this regard, an individual will buy stocks at prices that are below this level. In essence, this is buying stocks that are undervalued assets (Kapil, 2011). Classical theory The classical theory follows the belief that the price of a stock is equal to the best estimate of the stock’s value. This equality means that the undervalued stocks are not real. It is futile to determine or find them. A stock price always equals the present value of expected dividends. Under the EMH, every instance that you sell or buy securities, you are...

...Financial Market Definition of 'Financial Market' Broad term describing any marketplace where buyers and sellers participate in the trade of assets such as equities, bonds, currencies and derivatives. Financial markets are typically defined by having transparent pricing, basic regulations on trading, costs and fees and market forces determining the prices of securities that trade. Some financial markets only allow participants that meet certain criteria, which can be based on factors like the amount of money held, the investor's geographical location, knowledge of the markets or the profession of the participant. Investopedia explains 'Financial Market' Financial markets can be found in nearly every nation in the world. Some are very small, with only a few participants, while others – like the New York Stock Exchange (NYSE) and the forex markets – trade trillions of dollars daily. Most financial markets have periods of heavy trading and demand for securities; in these periods, prices may rise above historical norms. The converse is also true – downturns may cause prices to fall past levels of intrinsic value, based on low levels of demand or other macroeconomic forces like tax rates, national production or employment levels. Information transparency is important to increase the confidence of participants and therefore foster an efficient financial marketplace. Financial Markets: Capital Vs. Money Markets ...

...Investor Irrationality and Self-Defeating Behavior FIN645 Introduction For many years, finance traditionalists have held on to the theory that markets are efficient and that prices correctly reflect the information available to the market as a whole. This has come to be known as the efficient market hypothesis which was originally postulated by Eugene Fama in 1965. After a thorough statistical study of the movements of investment prices Fama concluded that “such movements were essentially random and unpredictable” (Shefrin p.75). Fama pointed out that “in an efficient market, prices correspond to intrinsic (or fundamental) value” (Shefrin p.75). In short, what the theory concludes is that it is impossible to beat the market; that no investor can ever purchase undervalued stocks or sell stocks at inflated prices. The market will always correct itself by incorporating all relevant information into the price of a security thus eliminating an individual investor’s ability to outperform. EMH has grown to become a cornerstone of financial theory and is still applied by many traditionalists when attempting to explain the behavior of financial markets. While there is much evidence in support of this theory there is an equal amount dissention. There are many who argue that there is ample evidence available that counters the central ideas of EMH and demonstrate its shortcomings such as: individuals who have shown that they can consistently beat the market...

...and Europe. The crisis has also shaken the foundations of modern-day financial theory, which rested on the proposition that our financial markets were basically efficient. Critics have even suggested that the efficient--market–hypotheses (EMH) was in large part, responsible for the crises. This paper argues that the critics of EMH are using a far too restrictive interpretation of what EMH means. EMH does not imply that asset prices are always “correct.” Prices are always wrong, but no one knows for sure if they are too high or too low. EMH does not imply that bubbles in asset prices are impossible nor does it deny that environmental and behavioral factors cannot have profound influences on required rates of return and risk premiums. At its core, EMH implies that arbitrage opportunities for riskless gains do not exist in an *Princeton University. I am indebted to Alan Blinder and to the participants in the Russell Sage Conference on Economic Lessons From the Financial Crisis for extremely helpful comments. 2 efficiently functioning market and if they do appear from time to time that they do not persist. The evidence is clear that this version of EMH is strongly supported by the data. EMH can comfortably coexist with behavior finance, and the insights of Hyman Minsky are particularly relevant in eliminating the recent financial crisis. Bubbles, when they do exist are particularly dangerous when they are financed with debt. And the housing bubble and its associated derivative...

...Efficient portfolio & Stock market efficiency Prepared by: Ahmed Mohamed Ahmed Zaki Nofal Submitted to: Dr.Tarek el Domiaty Modern portfolio theory Modern portfolio theory (MPT) is a theory of finance which attempts to maximize portfolio expected return for a given amount of portfolio risk, or equivalently minimize risk for a given level of expected return, by carefully choosing the proportions of various assets. Although MPT is widely used in practice in the financial industry and several of its creators won a Nobel memorial prize[1] for the theory, in recent years the basic assumptions of MPT have been widely challenged by fields such as behavioral economics. MPT is a mathematical formulation of the concept of diversification in investing, with the aim of selecting a collection of investment assets that has collectively lower risk than any individual asset. That this is possible can be seen intuitively because different types of assets often change in value in opposite ways. For example, to the extent prices in the stock market move differently from prices in the bond market, a collection of both types of assets can in theory face lower overall risk than either individually. But diversification lowers risk even if assets' returns are not negatively correlated—indeed, even if they are positively correlated More technically, MPT models an asset's return as a normally distributed function (or more generally as an elliptically distributed random...

... 2016 Efficient capital markets Market Efficiency An efficient capital market is: “A market where information regarding the value of securities are incorporated into its prices accurately and in real time. Since the value of securities fluctuates depending on the present value of future cash flows, an efficient capital market enables these fluctuations to be reflected in the securities' current price” (Investorwords.com, n.d.). What this means is that investors who invest among the stock market try and determine if the market is efficient, and whether it accurately emulates all of the influential prominent forces that are put on prices, and affected by such forces in real time. The efficient market hypothesis (EMH) is a theory among investors that states that it is impossible to out-smart the market because the efficient market always mirrors current events and information making it impossible to veer buy stock underpriced or overpriced – prices will always reflect the fair market value based on market influences. The only way to succeed in the market is to gamble with high-risk returns (Investopedia. n.d.). How this all works is investors will buy up stock and generate cash flow into the stock market, looking for a return on one’s investment. They are not always satisfied with a return; they want to maximize the return more than their competing investors – they want to beat the market somehow. But, based on the efficient market capital theory...

...EFB335 Tutorial Two Solutions 1. There are several reasons why one would expect capital markets to be efficient, the foremost being that there are a large number of independent, profit-maximizing investors engaged in the analysis and valuation of securities. A second assumption is that new information comes to the market in a random fashion. The third assumption is that the numerous profit-maximizing investors will adjust security prices rapidly to reflect this new information. Thus, price changes would be independent and random. Finally, because stock prices reflect all information, one would expect prevailing prices to reflect “true” current value. Capital markets as a whole are generally expected to be efficient, but the markets for some securities might not be as efficient as others. Recall that markets are expected to be efficient because there are a large number of investors who receive new information and analyze its effect on security values. If there is a difference in the number of analysts following a stock and the volume of trading, one could conceive of differences in the efficiency of the markets. For example, new information regarding actively traded stocks such as IBM and Exxon is well publicized and numerous analysts evaluate the effect. Therefore, one should expect the prices for these stocks to adjust rapidly and fully reflect the new information. On the other hand, new information regarding a stock with a small number of stockholders and low trading...

Jegadeesh and Titman (1993) theorise price momentum anomaly in the stock market for the first time. It contradicted to efficient market hypothesis thereby is widely debated. EMH states that no consistent excess return can be achieved since security prices fully reflect all available information (Fama 1970). Therefore, future prices cannot be predicted through technical analysis of past prices. If the hypothesis is true, passive investment strategy ought to be taken, because it is impossible to get abnormal return by aggressive trading. However, Jegadeesh and Titman show that stocks performed well over the previous 3 to 12 months tend to continue to perform well over 3 to 12 months holding periods. Buy past winners and short past losers earned statistically significant positive return of averaging 12.01% per year. Predictable price patterns and excess returns contradict the efficient market hypothesis. Investors and fund managers perform actively in pursuing abnormal profits.

...the hypothesis. It also examines the theoretical role and motivation of analysts in creating market efficiency; lastly it looks at alternative perspectives on the pricing of securities. Introduction In 1984 Warren Buffett penned an article titled “The Superinvestors of Graham-and-Doddsville”, based on a speech he had given on the occasion of the 50th anniversary of his mentor Ben Graham’s legendary textbook, Security Analysis. In it, Buffett rejected the then growing (and now entrenched) view in academia that markets are ''efficient'' because ''stock prices reflect everything that is known about a company’s prospects and about the state of the economy.'' Warren Buffett argued against EMH, saying the preponderance of value investors among the world's best money managers rebuts the claim of EMH proponents that luck is the reason some investors appear more successful than others. (Hoffman, 2010) This report will either agree with Buffet or somewhat sit on the fence. A market is said to be efficient with respect to an information set if the price ‘fully reflects’ that information set (Fama, 1970), i.e. if the price would be unaffected by revealing the information set...

...Lo To appear in L. Blume and S. Durlauf, The New Palgrave: A Dictionary of Economics, Second Edition, 2007. New York: Palgrave McMillan. The efficient markets hypothesis (EMH) maintains that market prices fully reflect all available information. Developed independently by Paul A. Samuelson and Eugene F. Fama in the 1960s, this idea has been applied extensively to theoretical models and empirical studies of financial securities prices, generating considerable controversy as well as fundamental insights into the price-discovery process. The most enduring critique comes from psychologists and behavioural economists who argue that the EMH is based on counterfactual assumptions regarding human behaviour, that is, rationality. Recent advances in evolutionary psychology and the cognitive neurosciences may be able to reconcile the EMH with behavioural anomalies. There is an old joke, widely told among economists, about an economist strolling down the street with a companion. They come upon a $100 bill lying on the ground, and as the companion reaches down to pick it up, the economist says, ‘Don’t bother – if it were a genuine $100 bill, someone would have already picked it up’. This humorous example of economic logic gone awry is a fairly accurate rendition of the efficient markets hypothesis (EMH), one of the most hotly contested propositions in all the social sciences. It is disarmingly simple to state, has far-reaching consequences for academic theories and business practice...

...1.- Problem statement and motivation How do Financial Markets participants make decisions? How do these decisions affect the financial markets? With the financial markets in Asia being the largest in the world, such an interesting environment with participants displaying different levels of capitalism, financial market experience and knowledge, Asia is definitely a fertile ground for the study od behavioral finance. According to conventional financial theory, the world and its participants are, for the most part, rational "wealth maximizers". However, there are many instances where emotion and psychology influence our decisions, causing us to behave in unpredictable or irrational ways. Asians in general suffer from cognitive biases, more so than Westerners, often being viewed as ‘Gamblers. Behavioral finance is a relatively new field that seeks to combine behavioral and cognitive psychological theory with conventional economics and finance to provide explanations for why people make irrational financial decisions .It calls for investigation into higher mental processes, memory, perception, problem solving and thinking .This paper looks at some of the anomalies (i.e., irregularities) that conventional financial theories have failed to explain. In addition, review underlying reasons and biases that cause some people to behave irrationally. 2.- Brief survey of the literature The following areas of research have been covered, from the mid 1980’s to the main focus of the article(special...

...the Efficient Markets Hypothesis (EMH) states that market prices fully reflect all publicly available information (Fama 1970). The EMH has been highly influential among academics, but practitioners and regulators appear unconvinced. Investors work hard to identify mispriced stocks on the basis of public data, or pay others to do so, even though the EMH asserts that such efforts are wasted. Managers seek to boost stock prices by hiding bad news in footnotes, and regulators work hard to defeat such efforts, even though the EMH asserts that information is reflected in prices no matter how obscure its presentation. Beliefs about inefficiency play a central role in the debate over recognizing expenses for incentive stock options. Opponents of expensing argue that the resulting lower net income will inappropriately reduce market prices, while proponents argue the market does not fully recognize compensation costs reported only in footnotes. In efficient markets, however, expensing these costs has no direct effect on prices, as long as the details of the compensation are included in footnotes. The decision to expense option costs could reduce stock price indirectly, even in efficient markets, by affecting the terms of contracts between the reporting firm and other parties (Watts and Zimmerman 1986). However, few of the parties to the debate appear concerned about these effects. The academic community is showing increasing dissatisfaction with the EMH, swayed partly by evidence that prices...
