We develop a new family of estimators of the covariance matrix that relies solely on forwardlooking information. It uses only current prices of plain-vanilla options. In an out-of-sample study we show that a minimum-variance strategy based on these fully-implied estimators outperforms several...

In this paper we develop the first estimator of the covariance matrix that relies solely on forward-looking information. This estimator only uses price information from a cross-section of plain-vanilla options. In an out-of-sample study for US blue-chip stocks we show that a minimum-variance...

Rationale Anleger sind im Allgemeinen risikoavers. Eine wichtige Implikation dieser Risikoaversion ist, dass Anleger für bestimmte Risiken, die sie eingehen, eine Kompensation verlangen – Risikoprämien. Ein Beispiel für solche Risikoprämien sind Momentenrisikoprämien. Sie sind definiert...

In this paper we develop a new family of estimators of the covariance matrix that relies solely on forward-looking information. These estimators only use current price information from a cross-section of plain-vanilla options and employ different higher moments of the implied return...
