Abstract

Le chapitre montre que les recommandations d'analystes sur le marché tunisien ont un impact sur les cours boursiers. Bien que faible, cet impact atteste d'une contribution à l'amélioration de l'efficience informationnelle. Ensuite, on montre que des portefeuilles suivant les recommandations ont des rentabilités excédentaires positives. Là encore l'ordre de grandeur est faible, mais il montre néanmoins que suivre les recommandations permet d'obtenir un profit supérieur à celui issu d'un suivi passif de l'indice de marché.
