Analysis of Capital Market Efificiency and the Efficient Market Hypothesis

Efficiency of capital markets includes evaluating changes in the price of securities over time. In this article, after briefly explaining the efficiency of capital markets, we will explain broadly the effective market hypothesis (EMH). This is the main theory that explains some of the main reasons for the volatility of securities prices. From this point of view, we will study the three forms of EMH efficiency, support and opposition claims, alternative theory, and potential modifications to the model.

The efficient market hypothesis is investment theory, see the "Efficient Capital Market: Summary of Theoretical and Empirical Studies" published in 1970, which was derived mainly from the concept of Eugene Fama's research findings. The basic idea proposed by Fama is to make the ROI over the market average as reflected in the key stock index like the Standard & Poor's 500 index. According to Fama's theory, investors may purchase shares that bring huge short-term profits to him in a lucky but in the long term he will actually achieve a return on investment that is far beyond the market average You can not.

Now, I know that you said that the market is random chaos. An efficient market hypothesis is that all market information is fully distributed and priced as assets, with the final market exceeding all members. This is totally nonsense. This is the only person who believes that this is a scholar, who has never paid. Information is absolutely ubiquitous. It is asymmetrical. And even if everyone gets the same information, we do not know how to handle it. Most people simply can not handle this information correctly and can not make the right decision. They can not separate signals from noise

Efficient Market Hypothesis and Evaluation of Random Walk An efficient market hypothesis is a widely accepted monetary theory accepted by most academic financial economists. It is widely believed that the securities market is very effective in reflecting information on individual stocks and the entire stock market. In a generally accepted opinion, news spreads quickly when information is displayed and is included in the security price without delay. Thus, when the term "effective market" was introduced in the economics literature in the 1960's, it was defined as the market "fully reflected" and "quickly adapted to new available information" market prices . Fama, 1970, p. 383. In this hypothetical context, "effective" experience means that the market can quickly summarize new information on economic, industrial, or corporate value and include it exactly in the price of the securities.
