Il "Correlation Breakdown" nella recente crisi finanziaria

Abstract

L'articolo presenta alcuni risultati significativi circa le modificazioni intervenute nei parametri delle serie storiche dei rendimenti borsistici in corrispondenza delle recenti crisi finanziarie. In particolare, si mostra che, nel periodo di crisi, le correlazioni aumentano di valore e divengono più uniformi: come conseguenza, la sinergia di questi due fenomeni rende più ardua una efficace diversificazione proprio nel momento in cui la riduzione e il controllo del rischio appaiono maggiormente necessari
