Valor en riesgo desde un enfoque de cópulas

Abstract

El valor en riesgo _ VaR_ es una medida que cuantifica los riesgos enfrentados por un portafolio. Entre los métodos de medición del VaR están la simulación histórica, la Simulación Montecarlo, los modelos paramétricos y los modelos de duración y convexidad. Para el cálculo del VaR se requiere modelar los retornos del portafolio y hallar la distribución de pérdidas que los describe. Tradicionalmente, se han supuesto retornos con distribución normal, pero la evidencia empírica rechaza esta hipótesis. Durante los últimos años se han adelantado investigaciones para calcular el VaR utilizando “cópulas”. Estas determinan la estructura de dependencia del portafolio y de los activos riesgosos que lo conforman, sin partir de supuestos sobre sus distribuciones. De este modo se obtienen resultados más realistas y se evita la sobrestimación o subestimación del valor en riesgo del portafolio.
