      "fr" => "L'assurance de portefeuille a traditionnellement pris deux formes : l'achat d'options de vente (put) et la duplication dynamique d'un profil de risque donné. Alors que la première méthode présente souvent un coût prohibitif et manque de flexibilité, la seconde ne conduit pas toujours au profil de risque attendu à cause des imperfections de marché comme l'illiquidité. Cet article montre comment des nouveaux produits financiers appelés "options sur krach" pourraient être utilisés par les investisseurs pour protéger leurs portefeuilles durant les périodes d'extrême volatilité."
      "en" => "Portfolio insurance has traditionally taken two forms: the buying of put options and the dynamic replication of a given risk profile. While the first method often presents a prohibitive cost and lacks of flexibility, the second method does not always lead to the expected risk/return profile due to market imperfections such as market illiquidity. This article shows how new financial derivatives called "crash options" could be used to protect investors' portfolios during periods of extreme volatility."
