Bu çalışmada BIST 30 endeksi
ile Dolar-TL kuru  üzerine yazılı
futures  kontratların sunduğu optimal hedge
rasyoları ve hedging etkinliği 
incelenmiştir. Çalışmada,  kapsamlı bir analiz sunulması amacıyla, hem
DBEKK, CCC-GARCH, DCC-GARCH, GOGARCH-ML ve GOGARCH-NLS modellerinden oluşan
dinamik hedging stratejilerine hem de OLS, VAR, ECM ile kısa ve uzun hafızalı
GARCH modellerine (GARCH, GJR-GARCH, FIGARCH, FIEGARCH) dayalı statik hedging
stratejilerine yer verilmiştir. En uygun modelin belirlenmesinde ise minumum
varyans yaklaşımı ile ortalama varyans yaklaşımına dayalı fayda fonksiyonundan
yararlanılmıştır.Çalışma bulguları, BIST30 endeksi için DBEKK modeli tarafından
sunulan optimal hedge rasyosunun; Dolar-TL kuru içinse GOGARCH-NLS modeli
tarafından sunulan optimal hedge rasyosunun hedging etkinliğinin daha iyi
olduğunu göstermektedir.

Anahtar Kelimeler
