Abstract

Las metodologías tradicionales utilizadas para calcular el valor en riesgo y el valor en riesgo condicional usualmente modelan el primer y segundo momento de las series, suponiendo que el tercer y cuarto momento son constantes. En este documento se utiliza la metodología de Hansen [1994] para modelar los primeros cuatro momentos de la serie, en particular, se usan varias formas paramétricas para modelar la asimetría y curtosis. Las medidas de VaR y CVaR tradicionales y las propuestas son calculadas para la Tasa Representativa del Mercado, los TES, y el IGBC para el periodo diario comprendido entre enero de 2008 y febrero de 2014. En general, se encuentra que las medidas de riesgo de mercado presentan mejor desempeño al modelar la asimetría y la curtosis.
