"The efficient of the market survives the challenge of literature on anomaly in the long-term returns. In accordance with the hypothesis of the efficient of the market that anomaly is the results of chances, on the clear reaction to information, it am almost as common as of one sub-reaction, and subsequent chase in event of abnormal before event is sick am almost so frequent as the return later in event. The most important thing, in accordance with the prophecy of the effectiveness of the market which visible anomaly can owe to the methodology, the majority of anomaly in the long-term returns tends to disappear with reasonable changes in competences.

COMMON FORMS OF EFFICENT MARKET HYPOTHESIS
There are three following common forms of efficient market hypothesis. These are given below.
Weak-form efficiency
Excesses of outputs cannot be earned by using strategies of investment founded on the lessons of historical actions. Techniques of technical analysis will not be capable of producing redundant outputs always, although certain forms of the fundamental analysis can again give the upper output. The prices of actions do not introduce dependency of series, what means that it is not a "models" at the prices of assets. It implicates that the movements of future prices are entirely determined by information not contained in valuable series. As a result, prices have to follow an unpredictable step.
Semi-strong-form efficiency
Semi strong form efficient implicates that the lessons of actions to fit to new publicly available information very fast and in a not anomalous way, so that no redundant output can be earned by negotiation on this information. Semi strong form efficiency implicates that neither the fundamental analysis, nor the techniques of technical analysis will be able to produce in a dependable way redundant outputs. To make out a will effectiveness Semi strong form efficiency, adjustments in unknown news have to be of a reasonable size and must be instantaneous. To test it, shape adjustments in increase or in fall after initial change must be searched. If it adjustments that such, it suggests that the investors had interpreted information in a partial and, leaving manner, in an ineffectual way.
Strong-form efficiency
The prices of actions reflect all information, public and private, and nobody can acquire a redundant output. If there are juridical obstacles to private information form becomes public, only of laws trading of initiating, strong effectiveness - am impossible, safe in case laws is in general ignored.To test Strong-form efficiency, a market needs to exist, where the investors cannot always acquire redundant outputs over a long period of time. Even if certain administrators of fund are regularly noticed to beat the market, no confutation of strong effectiveness - following form: with hundreds of thousand administrators of fund across the world, even a normal distribution of outputs (as effectiveness predicts) must be envisaged to produce someone dozen of "star" artists interpreters or performers

EMH BY ALLAN JHON (Chinese Stock Market)
The effectiveness of markets divided into information on effectiveness and effectiveness of allocation of means. The effectiveness of information refers to efficient Hypothesis market (EMH), which was one of the most popular research domains in finance. The general conclusion of numerous studies in the developed countries, starting with Fama (1970) is that the weak form of the effectiveness of the market holds. Fama hypothesis that if a market is efficient in weak form, the historical data of the past prices cannot be used to exploit a regular model of output for the getting of abnormal outputs. Based on the frame of Fama, it applies to empirical studies of the Chinese Stock Market walked. Chinese Supply Market was effectiveness of week-form since 1997. After on 1997, the effect weekend disappeared and the technical analysis becomes not useful. Reactions to valuable announcements. Dividend in actions and announcements of results. Conclusion is that the Chinese's Stock Market is not semi-very much efficient. The elements of solid proof of the existence of the insider trading. Chinese government plays an important role, its intervention has an influence hard on markets. Besides, structure fractals Chinese markets, it is memories of stock exchange outputs. As for the research of effectiveness of sharing out. The prices of actions on the secondary market have not enough correlation with the results of the society and in most cases influenced by the fluctuations of the market and the commentator of hits of the market. Besides, solid proof of bubbles on the Chinese stock markets. In conclusion, the effectiveness of sharing out is rather weak

EMH(Thai stock market) by Sethapong Watanapalachaikul and Colin Clark
The involvement of tests for the hypothesis of the efficient market of the Thai stock market is that the market was not efficient during period in study because it had strong chances that the investors or the stock exchange analysts can use historical data to acquire extraordinary winnings by buying and by selling actions. Studies such as Islam and Oh (2003), Fama (1991), and Seyhun (1986) admit that the semi-strong and weak form of EMH constituted the foundation of the most part of empirical researches. The result of tests confirms the presence of autocorrelation on the outputs of the Thai stock markets, what implicates that the market fell in a form of EMH. However, the theory of the behaviour of stock markets and anomaly provides proof against EMH. Efficient strong form of market suggests that the prices of titles always reflect all available information, including private information. The semi-strong form of EMH maintains that Stock Exchange prices reflect all available information, it is not therefore not underestimated or overestimated by titles, and the systems of exchange are unable to produce the upper outputs. The weak form of hypothesis suggests that the past prices or statements reflect future prices or returns and the technical analysts could use different models of prediction and the technical analysis to envisage the movement of supplies and make extraordinary winnings. However, Fama (1991) enlarged the concept of weak form to include predict the future output of the use of macroeconomic or accounting variables.
EMPERICIAL TEST OF EMH
As everything in economy, answer to be known if or not financial markets are efficient domiciles in the proverbial "grey zone ". As suggested it, the best answer is in weak-willed persons - someplace form in the range under semi-strong form. Near more important, however, me take a new look at additional subjacent hypotheses more the hypothesis of effectiveness of the market of debate. For instance, it discussed hypothesis that all participants in the market to interpret information in a similar manner, but hypothesis that the participants on financial markets are rational (financial markets are efficient? ) is also too much far. It is true that universal rationality is not a condition. absolute of the hypothesis of effectiveness of the market, but there is not enough proof to support the position according to which an irrational behaviour draws the price of a given supply am also in both directions and neutralize so herself. Besides, notion that all participants of the market have access to any elements of information is easily refutable. These arguable hypotheses, "grey" in their own right, are not purely and simply to cancel the Hypothesis of effectiveness of the market, but rather, their status should be a recall of warning that the realities of the economic world is not easily registered in well delimited categories.
CONCLUSION:
Markets are neither completely efficient, nor completely inefficient. All markets are efficient to a certain extent, some more than others. Rather than to be a question of the efficient of the black or white market, a question of nuances of grey is more. In markets having an important insufficiency of efficient , the investors most informed can try hard to surpass the least well-informed. Markets of state obligations for instance, are considered as extremely efficient. The most part of the researchers lean over big capitalization also to be very efficient, while supplies with weak capitalization and international actions are considered by some as less efficient. Property services and of venture capital, which do not have fluid markets and uninterrupted, are considered as less efficient because the different actors can have variable quantities and quality of information.
