Valor en Riesgo mediante un modelo heterocedástico condicional α-estable.

Abstract: ResumenEl objetivo de esta investigación es describir y comparar la estimación del Valor en Riesgo (VaR), considerando un modelo GARCH univariado con la innovación de la distribución α-estable. Los resultados estadísticos sugieren que el modelo VaR α-estable proporciona estimaciones del VaR más precisas que el modelo bajo la hipótesis gaussiana, el cual subestima significativamente el VaR en períodos de alta volatilidad. Por el contrario, en el período posterior a la crisis, el VaR al 95% bajo la hipótesis gau… Show more

“…Similarly, Mohammadi (2017) analyzed the volatility predictive performance of the stable-gaRch and stable power-gaRch models and applied this method for predicting future values of the S&P500 stock market. Khindanova, Rachev, & Schwartz (2001) applied stable distribution in VaR modeling the forecast evaluation shows that stable VaR outperforms the normal modeling, Serrano & Mata (2018) compared the VaR estimation under the stable and normal gaRch approach before, during and after a crisis period, the results provide evidence that the stable model provides better VaR estimates than the normal one during a crisis period but in tranquility periods, it overestimates the potential losses.…”
