VALOR EN RIESGO CON APROXIMACIONES CUADRÁTICAS

VALOR EN RIESGO CON APROXIMACIONES CUADRÁTICAS

Abstract

En este trabajo se propone un enfoque cuadratico para el calculo del Valor en Riesgo (VaR) para un portafolio con n activos y m factores de riesgo, basado en la expansion Cornish-Fisher y en el calculo de la delta y la gamma de cada activo. Esta metodologia presenta ventajas sobre tecnicas de simulacion basadas en la valoracion total de la posicion ya que es menos intensiva computacionalmente, y sobre tecnicas basadas en aproximaciones lineales las cuales tienden a sobreestimar la posicion en riesgo cuando el portafolio contiene activos no lineales con respecto a su factor de riesgo asociado, el cual se distribuye normalmente.
