historical sequence of prices, rate of returns, trading volume. Under this form, the

It assumes that security prices adjust rapidly to release public information .It
encompasses both historical sequence and public information .In a semi strong
form, the fundamental analyst are of no use since they use public financial ratios
to analyses securities.

above average profits. The implication of this is that even the insider trading is of
no use, it encompasses both the weak form and the strong form.
