Modelització de dades financeres mitjançant models Garch

Abstract

The aim of this undergraduate thesis is to get into the world of volatility models and forecasting. It is also wanted to familiarize myself with the economic environment and vocabulary. To make that possible, a basic study about the ARCH/GARCH model family is done. The thesis could be divided in three sections. The first one, an introduction of previous models and concepts needed for the study. Secondly, the development of the ARCH theory, and finally, the practical study of the SP500 index where we use the knowledge aquired during previous chapters.
