Abstract: In this paper we test the weak form of the efficient-market hypothesis (EMH) using weekly data of stock prices from eight transition markets during the period 2000–2015. This is accomplished by using quantile unit root test. Our empirical results indicate that the stock markets are efficient in the weak form for most of the markets, except for Bulgaria, Romania, and Russia. The results imply that in many of these countries one cannot enjoy excess returns to their investment.
