Abstract

In this study, we examine whether the efficient market hypothesis is valid in the Istanbul Stock Exchange (ISE) via parametric and semi parametric long memory models. In order to determine the presence of weak form efficient market hypothesis, we consider 10 sector indices. Semi parametric and parametric long memory model results suggest that the volatility of sector returns exhibit long memory properties and hence it can be said that the ISE is not efficient market.
