L. Gagnon et G. Lypny, THE BENEFITS OF DYNAMICALLY HEDGING THE TORONTO-35 STOCK INDEX, Canadian journal of the Administrative Sciences Association of Canada, 14(1), 1997, pp. 69-78
A growing number of studies reveal that the performance of dynamic hed
ging strategies tends to vary across markets, producing large percenta
ge reductions in variance in some and seemingly small reductions in ot
hers, relative to constant hedges. This paper examines the hedging eff
ectiveness of Toronto 35 index futures and shows that the application
of a dynamic strategy based on a general, bivariate GARCH(1,1) process
yields economically significant in-sample and out-of-sample improveme
nts in risk reduction, compared to static hedging strategies.
