El objetivo de este trabajo es evaluar diferentes metodologías para estimar el VaR de un portafolio compuesto por tres monedas, el peso colombiano, el real brasilero y el peso mexicano. La evaluación se hizo por medio de la comparación empírica de los siguientes métodos: Simulación Histórica, Volatilidad Constante, Promedio Móvil con Ponderaciones Exponenciales, y tres modelos Garch multivariados: Diagonal VECH, Constant Conditional Correlation y Diagonal BEKK. Por medio de las pruebas de Kupiec (1995), López (1998) y Christoffersen (1998) fue posible determinar que el modelo de Volatilidad Constante no ofrece la cobertura deseada y que el modelo GARCH multivariado Diagonal BEKK, de varianza no constante, ofrece la cobertura deseada y presenta menores pérdidas.
The purpose of this paper is to evaluate different methods to estimate VaR for a portfolio of Colombian peso, Brazilian real and Mexican peso. The evaluation was done thru the empirical comparison of the following methods: Historical Simulation, Constant Volatility, EWMA, and three multivariate GARCH models: Diagonal VECH, Constant Conditional Correlation and Diagonal BEKK. Backtesting proved that the constant volatility model does not offer the coverage needed, but MGARCH model, Diagonal BEKK, outperformed the other models.
