Introduction: Efficient Market Hypothesis (EMH) implies markets to be rational, incorporating new information to reflect in stock prices rapidly, considering direction and size of the share price movement.

G 34 Weak Form Market Efficiency of Dhaka Stock Exchange (DSE), Bangladesh 1. Introduction The theory of efficient market hypothesis (EMH) proposed by Fama (1965) was a ‘water shed event’ in the capital market research.

Behaviorists believe that numerous factors—irrational as well as rational—drive investor behavior. In sharp contrast

Chapter 16: Market efficiency: Concept of market efficiency An efficient market has been defined as one in which the prices of securities fully reflect all available information. This requires that the reaction of the market prices to new information should be instantaneous and unbiased.
