EMH Vs Behavioral Finance
Since the beginning of the 1970s, almost all financial economists believed in and accepted the efficient market hypothesis. Eugene Fama also known as intellectual father of the “efficient-market hypothesis” argued that it was impossible to “beat the market.” This idea was widely accepted because it held great sense and was easy to understand.
Mr. Fama began his studies in the 1950s when he worked on a market-forecasting newsletter. Mr. Fama realized that human beings were working with strategies that didn’t quite work out. Fama wrote in his 1965 paper “In an efficient market at any point in time the actual price of a security will be a good estimate of its intrinsic value.” This meant that the stock prices were changing everyday and there was no real was to predict what a stocks actual price would be in the future.
Efficient market hypothesis is very controversial and often times people go against the theory. In 1191, Famas theories began to fade away. Fama began to realize that there was no possible was that the market was efficient enough to predict the price of a stock or search for an undervalued stock. A good example would be when the economy goes into a recession. There was no possible way to predict that the economy would take a down turn so fast.
On the other side of the fence is the behaviorist group of economists. The behavioral finance concept is based on rational theories. The thought process is that people behave rationally and predictably. Richard Thaler, a member of the “behaviorist”school of economic thought changed this vision. He expressed concern that people tend to make irrational or stupid decisions.
Thaler collected much evidence that people constantly made irrational decisions that made absoluetely no sense financially. One of his examples was a tennis player who kept playing tennis with a bad elbow even just so he would not waste the club membership fees. It is very irrational that this tennis player would risk

    Warren Buffet, known as one of the most successful investors in history, is convinced that stock markets are inefficient. ' 'I think it 's fascinating how the ruling orthodoxy can cause a lot of people to think the earth is flat. Investing in a market where people believe in efficiency is like playing bridge with someone who has been told it doesn 't do any good to look at the cards ' ' (Buffet, 1984, as cited by Davis, 1990, p.4).…

    4. Efficient market hypothesis is the theory that asset prices reflect all publicly available information about the value of an asset. One piece of evidence that is consistent with this theory are the shares of companies in the stock exchange. The news and public information on a company greatly affects the demand of shares in a particular company and if the demand rises, so does the price. If the demand falls, the price will drop as well. Just by looking at the history of a stock’s prices, it will give general knowledge on how well a stock will do in the future.…

    Lastly many prominent academicians and financial institutions have called into question the efficacy of the efficient market theory due the financial bubble created in the financial markets. That fact that market price of a stock represents the fair price has been called into question.

    As Chapter 10 questions, if further evidence continues to surface that capital markets do not always behave in accordance with the efficient market hypothesis, then should we reject the research that has embraced the EMH as a fundamental assumption? In this regard we can return to earlier chapters of this book in which we emphasised that theories are abstractions of reality. Capital markets are made of individuals and as such it would not (or perhaps, should not) be surprising to find that the market does not also act in the same predictable manner. Nevertheless, the EMH has helped provide some useful predictions and no doubt will continue to be relied upon by many researchers for a considerable period of time. As Lee (2001, p.238) states:…

    The first one of them Eugene Fama is an American economist born in 1939 and working at the University of Chicago. He is the author of the theory that asset prices perfectly reflect all available information. Fama was mainly honored for his researches done in 1960’s and his theory that asset prices are “extremely hard to predict over short horizons.” He claims that this theory was influenced by the fact that while working as an undergraduate at the Tufus University he noticed that the forecasting schemes - which he was in charge of checking - awfully failed to function. He later coined the term "efficient markets" to describe his view that asset price movements could not be predicted because prices fully reflected all available information. That theory was briefly summarized by another economist Burton Malkiel, who said “a blindfolded monkey throwing darts at a newspaper’s financial pages could select a portfolio that would do just as well as one carefully selected by experts.”. Later on that theory was tested even with the use of real monkeys and after confirming it, it has influenced the way millions of people now invest, contributing to the popularity of index funds that hold broad, diversified baskets of equities.…
