GENELLEŞTİRİLMİŞ HİPERBOLİK DAĞILIMLAR İLE RİSKE MARUZ DEĞER: BIST100 ENDEKSİ ÜZERİNE BİR UYGULAMA

Riske Maruz Değer(RMD) uygulamalarında getiri dağılımı üzerine yapılan varsayımlar önemli bir rol oynamaktadır. Yıllar içinde yapılan çalışmalar göstermiştir ki birçok finansal ürüne ait günlük getiri dağılımları, kalın ya da yarı-kalın kuyruk yapısı sergilemektedir. Bu çalışmada, 2010-2016 dönemi için BIST100 endeksine ait günlük getiriler yarı-kalın kuyruk yapısı sergileyen Genelleştirilmiş Hiperbolik Dağılımlar(GHD) ile modellenecektir. Bu amaçla, GHD ve aileye ait Normal Ters Gauss Dağılımı ile Genelleştirilmiş Hiperbolik Çarpık-t dağılımı için günlük getiriler kullanılarak parametre tahminleri yapılacak ve dağılımların uygunluğu test edilecektir. Son olarak, elde edilen parametre tahminleri kullanılarak RMD yöntemi ve GHD ailesinin performansları geriye dönük testlerle karşılaştırılacaktır.
