Estudio de modelos de heterocedasticidad condicional en acciones

Abstract

El objetivo de este trabajo es el estudio del comportamiento a lo largo del tiempo de una serie de acciones, centrándonos en la modelización de la heterocedasticidad condicional y de la volatilidad, para poder realizar predicciones y calcular datos interesantes como el Value at Risk. Utilizaremos para ello distintos modelos GARCH, con y sin asimetría para elegir el mejor. Además, crearemos una cartera equiponderada con las 3 acciones elegidas para analizarla. Gracias a este trabajo se podrá observar cómo se puede aplicar la econometría para estimar los comportamientos de la economía en la realidad. Los resultados indicarán que las acciones y la cartera contienen volatilidad y que en la mayoría de casos es mejor estimarla con modelos de shocks asimétricos (GJR y TARCH) que con el modelo simplificado GARCH.
