This article examines the performance of various hedge ratios estimated from
different econometric models: The FIEC-FIGARCH model is introduced as a new model
for estimating the hedge ratio. Utilized in this study are KOFEX futures data, along
with the ARFIMA-FIGARCH approach, the EC model, and the VAR model. Our analysis
identifies the prevalence of a fractional cointegration relationship. The effects of
incorporating such a relationship into futures hedging are investigated, as is the
relative performance of various models with respect to different hedge horizons.
