In standard static Mean-Variance approach portfolio is presented by one allocation vector optimized in terms of expected returns & variance-covariance (VcV) matrix. Such one-dimensional approach is not suitable for Fixed Income: i) portfolio cannot be described by allocation vector only, and ii)...

This paper provides extensions to existing procedures for representing one-factor no-arbitrage models of the short rate in the form of a tree. It allows a wide range of drift functions for the short rate to be used in conjunction with a wide range of volatility assumptions. It shows that, if the...

We study the term structure of variance swaps, equity and variance risk premia. A model-free analysis reveals a significant price jump component in variance swap rates. A model-based analysis shows that investors' willingness to ensure against volatility risk increases after a market drop. This...

This article presents and compares two different Kalman filters. These methods provide a very interesting way to cope with the presence of non-observable variables, which is a frequent problem in finance. They are also very fast even in the presence of a large information volume. The first...

Examines the movements of the crude oil futures prices' curve in Great Britain. Relationship between the spot price and futures prices for different delivery dates; Problems in identifying the crude oil prices' movements; Factors that affect the movements of crude oil prices.

Cet article s’appuie sur une analyse en composantes principales pour identifier les mouvements des courbes de prix du pétrole brut. L’étude confirme que trois composantes permettent d’expliquer les fluctuations des prix à terme : déplacement parallèle, pentification, et courbure. De...

Whereas the spatial integration has already been examined in commodity markets, empirical tests on temporal integration have never been carried out. Relying on the “preferred habitat” theory, which is applied to the crude oil market, this article investigates whether this market is segmented...
