EFFICIENT-MARKET HYPOTHESIS

If we consider this term from financial market point of view that it means that the financial market is very much efficient from information point of view. Specific prices on which all the important stocks of online stock trades are trades already depict all the important information of market strength and company’s strength as well. These prices of online stock trades are also very much reliable in providing the pricing rates of near future in online stock trades. These all information informed us that it is not possible for outperforming the market with the information provided by the market of online stock trades. The only factor of outperforming is the luck which plays an important role in getting success in online stock trades’ market.
Information and knowledge collected in efficient market hypothesis can be defined as; it is the information which can affect the pricing value of nay stock in online stock trades which is not known by any one at the present time but which can occur in future in any random manner. But with the time passes, this hypothesis become the centre of criticism for people who are the believer of rational market in spite of relying on the current crisis of financial market of online stock trades.

Efficient market theory of online stock trades was introduced by a professor Fama which was teaching in Chicago booth school and doing PHD from there also, and he has introduced this theory during his academic research for Ph.D. thesis and it was published from the panel of that school in the early of 1960s. But this theory of online stock trades’ market was accepted by the people widely in 1990s. Empirical analysis always found continuous problem with the basic concept of efficient market hypothesis when the situation occur of low price to earning out perform the remaining stocks of online stock trades. This theory becomes the controversial substance in 2000 but still it is accepted as a worth whiling startup point.

HISTORICAL BACK GROUND:

Originally, efficient hypothesis theory of online stock trades was generated by Louis who was French mathematical in 1900. But unfortunately his research was completed neglected until the mid of 1900. When a little observing study explains that US online stock trades’ pricing values in financial market make their fluctuation according to the regular interval of random model.

This theory received its required importance in the 1960s when Paul has circulated the Bacheleir’s study strongly among the economical experts. Afterwards in 1964, Bachelier’s research and empirical studies together were published. Later on, in 1965, Fame utilized this theory in his Ph.D. work and presented with some modifications.

In 1980s a study was made by firth that belongs to United Kingdom, in which he has compared existing shares pricing values of online stock trades and after the announcement of bid when offered. Firth has also observed that stock of online stock trades is controllable with respect to their corrected level of online stock trades. In future David Derman has made criticism against the word “efficient” that the immediate response collected from the online stock trades’ market can not be considered as “efficient”.
