This study considers calibration to forward‐looking betas by extracting information on equity and index options from prices using Lévy models. The resulting calibrated betas are called Lévy betas. The objective of the proposed approach is to capture market expectations for future betas through optio

Abstract
Portfolio managers use index futures for a variety of reasons. Regardless of their motivation, they will keep a close eye on the relation between the index futures returns and their stock‐portfolio returns. Whenever this relation is perceived to have changed, the manager will decide whether it is worthwhile to rebalance the index futures—portfolio mix accordingly. Exact measures as to when and how much rebalancing should occur have not yet been established. This article proposes a dynamic hedging algorithm based on a reverse order CUSUM‐squared (ROC) testing procedure, first discussed in M. H. Pesaran and A. Timmermann (2002). A comparison with standard alternatives (naïve, expanding, EWLS, and rolling estimation windows) finds limited improvements in hedging performance, both in‐ and out‐of‐sample. © 2005 Wiley Periodicals, Inc.

## Abstract In a number of earlier studies it has been demonstrated that the traditional regression‐based static approach is inappropriate for hedging with futures, with the result that a variety of alternative dynamic hedging strategies have emerged. In this study the authors propose a class of ne
