Análisis de series temporales financieras: modelización ARIMA

Abstract

[spa] En este documento se evalúa la serie de cotizaciones máximas semanales del IBEX-35 con el objetivo de formular un modelo de series temporales capaz de sostener el comportamiento de dicha serie y, a su vez, ofrecer predicciones óptimas. Para el desarrollo del análisis, se exponen, en primer lugar, los aspectos formales de la modelización ARIMA. A continuación se presenta el esquema a seguir para el estudio de la serie, la metodología Box-Jenkins. Este protocolo se centra en: la identificación del modelo; la estimación del mismo, a través del programa econométrico Gretl; la validación del modelo, mediante los contrastes estadísticos necesarios; la predicción, con las correspondientes conclusiones. Finalmente se alcanza la conclusión que el modelo ARIMA(1,1,0) replica adecuadamente la serie.

[eng] This document evaluates the series of maximum weekly prices of the IBEX-35 with the aim of formulating an appropriate time series model to capture the behavior of that series and, in turn, offer optimal predictions. For the development of the analysis, first, the formal aspects of the ARIMA modeling are exposed. Then, the scheme to follow for the study of the series, the Box-Jenkins methodology, is presented. This protocol focuses on: model identification; its estimation; model validation through a set of diagnostic tests; and prediction, with the corresponding implications. Finally, it is concluded that the ARIMA(1,1,0) model adequately replicates the series.
