Abstract

El reciente desarrollo de los mercados financieros en Colombia pone de manifiesto la importancia de ver el grado de integración de este con el entorno internacional. De acuerdo con la teoría de portafolio, para la conformación de un portafolio eficiente, se debe combinar activos de diferente riesgo para obtener el mayor retorno esperado posible, teniendo en cuenta que puede existir correlación entre los activos. En ese sentido, se busca evidencia del grado de correlación que existe entre los principales activos del mercado local y activos del mercado internacional. En particular, los activos del mercado local (dólar, bonos de la Tesorería y acciones) y el mercado extranjero (en particular bonos del Tesoro de Estados Unidos) deberían presentar una correlación alta para considerarse sustitutos en una eventual construcción de un portafolio eficiente. En busca de éstos hechos estilizados, se utilizan dos metodologías (Filtro de Hodrick y Prescott (1997) y primeras diferencias de las variables) para la estimación de correlaciones contemporáneas y no contemporáneas entre los diferentes activos. Sin embargo, la evidencia muestra que la relación que existe entre los activos locales y los extranjeros no permite ser concluyente sobre el tema. ************************************************************************************************************ Recent development of the financial markets in Colombia, emphasizes the importance of relation between local markets and the world economy. The portafolio theory says that the conformation of efficient portafolio has to combine assets of different risk to get the maximun expect profit, taking on account that it can exist correlation between the returns of the assets. This paper seeks evidence about the correlation between the main group of the assets on the local market and assets on the internacional markets. The assets on the local market (stocks, currencies, treasury bonds) and the internacional markets (partucularly treasuries) has to show hight correlations to be consider substitute in the construction of efficient portafolio. To prove this evidence, it is used two metodologies (Hodrick and Prescott filter (1997) and the first difference of the variables) to check the contemporary and no contemporary correlations between the returns of local and international assets. The evidence shows that the correlation between these two types of assets is low, and is not allow take a conclusion about this matter.
