Efficient Market Theory If beatin g the market is impossible, how come Warren Buffet is consistent in outperforming the market? There are so many correlative fund and portfolio managers giving consistent performance in the stock markets, which is not possible according to this theory. There is always scope for outperforming the markets thorough experience, expertise, intuition and discipline. The efficient market is an ideal situation which is hardly achieved in the real life. For example, Muhammad, N. M. N. and Rahman, N. M. N. A. (2010, p. 35) writes EMH states that security prices fully reflect all accessible information and will immediately adjust to the arrival of new information (Adam, 2004). However, since market was closed on both Saturday and Sunday, it was argued that investors cannot do anything with the market even though they got some information during the weekend.

In real life situations, perfect efficiency in the market place is unrealistic, and it also depends upon accuracy of the information, cost of the information, the efficiency of the information transmission and the risk-return reward in taking decisions based on the information. Livanas, J. (2006, p. 28) argues how can the market be efficient when investors seem to make decisions that perhaps are rational but only within bounds? When the investors make decisions in an irrational manner, which is in line with the human behavior, it will be difficult to rely on a
