Abstract

L'analyse des corrélations, constitue le pilier d’une stratégie réussie de diversification du portefeuille d’actions. Plus faibles sont les corrélations au sein d’un même portefeuille, plus importants seront les profits potentiels que nous pouvons en obtenir. Dans un contexte local, ceci est équivalent à l’étude des corrélations entre tous les rendements des valeurs ciblées par un investisseur sur un seul marché. Mais à l’échelle internationale, cette tache devient plus difficile car on est appelé à analyser toutes les relations entres les rendements sur les différents marchés internationaux. Erb, Harvey et Viskant (1994) et Longin et Solnik (1995), ont démontré que ces corrélations, varient avec le temps selon des phases cycliques dans les économies. Nous allons alors étudier au niveau international, la relation entre les corrélations et la volatilité des rendements des indices boursiers de 4 pays : le Maroc, la France, les Etas Unis et le Japon, et ce, du 01/01/2002 au 31/12/2012 et essayer de trouver s’il existe ou non, une relation de cause à effet
