Bu çalışmada Binance coin (BCH), Bitcoin cash (BNB), Stellar (XLM) ve Cardano’dan (ADA) oluşan kripto para birimlerini içeren yatırımların yol açabileceği risklerin nasıl ölçülebileceği ve yönetilebileceğine ilişkin analizler üzerinde durulmuştur. Bu amaçla öncelikle van der Weide (2002) tarafından geliştirilen dört değişkenli GO-GARCH-NLS (Generalized orthogonal- general autoregressive conditional heteroskedasticity- non-linear least squares) modeli kullanılarak ilgili kripto para birimleri için zamanla değişen şartlı varyans, kovaryans ve korelasyon değerleri elde edilmiş, ardından Kroner ve Sultan (1993) ile Kroner ve Ng (1998) tarafından geliştirilen yaklaşımlar dikkate alınarak optimal portföy ağırlıkları ile optimal hedge rasyoları belirlenmiştir. Çalışmada ayrıca hem tekil kripto para birimleri hem de bu kripto para birimlerine dayalı olarak oluşturulan optimal portföyler için kısa ve uzun pozisyonlar dikkate alınarak yeniden örnekleme yöntemine (boostrapped) dayalı tarihi simülasyon yöntemi ile piyasa riski ölçüm analizlerine yer verilmiştir. Tüm bu analizler sonucunda bu kripto para birimlerine dayalı olarak beklenen getiri oranlarında bir değişikliğe yol açmadan riski minimize eden optimal portföy ağırlıklarının nasıl belirlenebileceği, bu optimal portföylerin taşıdığı piyasa riskinin ve sağladığı çeşitlendirme etkisin ne olduğu ve her bir kripto para biriminde taşınabilecek uzun (kısa) pozisyonların yol açabileceği risklerin diğer para birimlerinde taşınabilecek kısa (uzun) pozisyonlar ile nasıl hedge edilebileceği gibi konulara dönük olarak önemli bulgulara ulaşılmıştır.
