We investigated the weak-form market efficiency of nine daily sectoral indices of Malaysian stock market between 1996 and 2006. The structural break unit root tests evidenced most of the price indices characterized by mean-reverting process that violated the random walk process. These empirical results were in sharp contrast with the traditional unit-root test which ignored the economic crisis and currency control. Our findings concluded that the Malaysian sectoral stock markets were weak-form inefficient (except the property index) under the structural change.
