Abstract

Il paper si propone di presentare i concetti fondamentali e le applicazioni di alcune promettenti teorie intese a rappresentare i mercati finanziari come sistemi dinamici complessi che evolvono tra diversi stati, caratterizzati da distinte configurazioni di rendimento e rischio. In particolare ci si sofferma sul modello del mercato azionario di Vaga, basato sul modello del ferromagnetismo di Ising, evidenziandone le possibili applicazioni all'analisi e alla previsione della volatilità.
