Abstract

El artículo indaga sobre la existencia de ganancias para un inversionista local en términos de eficiencia, minimizando la volatilidad del portafolio, a partir de la cobertura del riesgo cambiario inherente. Para la estimación del portafolio óptimo de mínima varianza se utiliza una metodología robusta la cual permite hacer inferencia estadística acerca de si la diversificación internacional reduce el riesgo para un inversionista local. La metodología se aplica a portafolios de acciones en el caso de un inversionista colombiano y uno mexicano, para concluir que el empleo de coberturas cambiarias puede reducir el riesgo, con la posible excepción de que la correlación entre la divisa y el índice local sea bastante negativa, lo cual haría más conveniente dejar el portafolio sin cubrir.
