WHAT IS AN EFFICIENT MARKET AND HOW DOES IT AFFECT INDIVIDUAL INVESTORS?

In this paper we give some definition of the Efficient Market Hypothesis (EMH) and discuss the effect of EMH on individual investors. In order to answer report question we gave a brief explanation of the forms of market efficiency. Gave examples of some investors and tried to seek evidence that EMH is fair. Market efficiency was developed in 1970 by economist Eugene Fama. Who says that it is impossible to "beat the market" using all available information. Even if one has an insider, you cannot use it for forecasting of future prices. It makes useless all analysis doing by investors. Since the EMH contradicts the basic assumptions of the traditional approaches to forecasting of prices, it causes a lot of controversy, which led to repeated attempts to confirm or refute it. In the paper, we examined various forms of market efficiency. It is difficult to have abnormal profit on the market with strong market efficiency.
