Abstract

Le caractère partiellement prévisible de la rentabilité des actions suffit pour déduire qu'à un instant donné les détenteurs d'actions qui sont rationnels exigent non pas une prime de risque mais une gamme de primes paramétrées par l'horizon de placement. En exploitant les anticipations du prix des actions cotées au NYSE telles qu'elles sont révélées par les enquêtes de J.Livingston, cet article analyse la dynamique des primes de risque ex-ante suivant quatre horizons allant de six mois à l'infini. Conformément aux attentes théoriques, les différences entre ces primes sont de grande ampleur et variables au cours du temps. Cependant, l'analyse économétrique montre qu'il existe des informations communes à toutes les primes (volatilité, facteurs macroéconomiques) et qu'il existe une cohérence dans leurs dynamiques respectives, les primes d'horizons plus courts tendant à s'ajuster sur les primes à horizons plus longs. Ces résultats montrent que tout se passe comme si les experts ne croyaient pas en l'efficience du marché des actions.
