The authors use a variance ratio test to test the weak form of market efficiency as regards capital markets in the Czech Republic, Slovakia, Hungary, Poland, and in the United States. Market efficiency was tested using weekly and monthly values of relevant market indices in a period from 1993 until August 2004. The main results of the research show that (1) the weak form of the efficient market hypothesis could not be rejected for Central European capital markets; (2) market efficiency was observed over time on all the observed markets; (3) the Central European capital markets converged to the U.S. capital market (in terms of the weak form of market efficiency).
