Suppose that spot and futures prices are generated from an errorcorrection model. This note demonstrates that, although the OLS model is misspecified, it provides a hedge ratio that usually outperforms the hedge ratio derived from the correct error-correction model. The opposite result is possible o

Abstract
This note considers the hedging effectiveness of a dynamic hedge strategy as compared to the conventional OLS strategy. The conditions for the superiority of the OLS strategy are identified. It is argued that these conditions are frequently satisfied and therefore one expects to find the dominance of the OLS strategy over any dynamic strategy in the empirical work.

## Abstract We characterize conditions under which the regime switching (RS) hedge strategy will perform better than the ordinary least squares (OLS) hedge strategy. The result can be extended to the case where the GARCH effects prevail. Specifically, these conditions would allow the RSβGARCH hedge
## Abstract An option hedge ratio is the sensitivity of an option price with respect to price changes in the underlying stock. It measures the number of shares of stocks to hedge an option position. This article presents a simple derivation of the hedge ratios under the BlackβScholes optionβpricing
## Abstract This note provides an analysis to examine the conjecture about the monotonic relationship between hedge ratio variability and hedging performance. Specific conditions are characterized to sustain the conjecture. Β© 2010 Wiley Periodicals, Inc. Jrl Fut Mark
