Un théorème de séparation en (3 + K) fonds est obtenu au lieu de l'habituel (2 + K) fonds, où K est le nombre de variables d'état. L'efficience espérance-variance de M n'est nécessaire que lorsque seuls des actifs au comptant sont présents."
      "en" => "An intertemporal CAPM is derived, in which mean-variance efficiency of the market portfolio is neither necessary nor a sufficient condition, when, in addition to the usual cash assets, non-redundant futures contracts trade. A (3 + K) mutual fund separation is obtained in place of the usual (2 + K) fund, where K is the number of state variables. Mean-variance efficiency of the market portfolio is a necessary condition only when cash assets solely trade."
