Efecto del fin de semana y los festivos en los mercados de acciones: Un estudio comparativo entre Chile, Brasil, México y Colombia

Abstract

The discussion related to the market efficiency and its implications on business performance has been a constant topic in the economic and financial research. This paper follows this branch, analyzing the “weekend effect” on the return and volatility of the stock exchange index in Chile, Brasil, Mexico and Colombia. The research uses a GARCH-M model applied to the closing daily prices in order to isolate abnormal returns and volatilities related to the “weekend effect”. Furthermore, it makes a review of previous papers and its results.
