Definition: the semi-strong form efficiency is a type of efficient market hypothesis (emh), which holds that security prices adjust quickly to newly available information, thus eliminating the use of fundamental or technical analysis to achieving a higher return. Information in the price of shares would depend upon the form of efficiency viz, weak, semi strong or strong efficiency of the market as a corollary, the study on the effect of corporate information release on the price and volume of shares would reveal the type of efficiency of the market iii objectives.
