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; simulación Monte Carlo; modelos paramétricos y 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 normalmente distribuidos, pero la evidencia empírica muestra que éstos no se comportan así. En los últimos años, se han adelantado investigaciones para calcular el VaR utilizando cópulas, que determinan la estructura de dependencia del portafolio y de los activos riesgosos que lo conforman, sin partir de supuestos sobre sus distribuciones, obteniendo resultados más realistas y evitando así la sobrestimación o subestimación del valor en riesgo del portafolio.

Abstract: The value at risk VaR, is a measure that quantifies the risks faced by a given portfolio. There are some methods to calculate the VaR: historical simulation, Monte Carlo simulation, parametric models and duration and convexity models, among others. To calculate the VaR is required to model the portfolio returns and to find the loss distributions that describe them, traditionally those distributions are suppose to be normal distributed, but the empirical evidence shows the contrary. In the last few years, research in VaR calculation shows how copulas determine the dependence structure of a portfolio of the risky assets, without any assumptions regarding distributions, so you can find in it more realistic results and it is possible to avoid sub estimation of the value at risk of the portfolio.
