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...

This study investigates another calendar anomaly the literature does not yet address – the week-of-the-year (WOY) effect. Using the weekly returns on the stock market indexes of 20 countries worldwide, for a period that ends in December 2010, the findings demonstrate that returns in Week 44,...
