Petrolün Portföy Optimizasyonu İçin Önemi: Borsa İstanbul’da Yer Alan Petrokimya Plastik Firmaları Üzerine Bir Uygulama

Year 2019, Volume: 33 Issue: 4, 1245 - 1259, 25.10.2019

Abstract

Bu çalışma petrol ve petrokimya plastik sektöründeki firmalar
arasındaki oynaklık yayılımını ölçüp buradan elde edilecek varyans ve kovaryans
serileri ile portföy optimizasyonuna bakmayı amaçlamaktadır. Veriler 9 Haziran
2015 ve 3 Mayıs 2019 tarihleri arasını kapsamakta olup, Batı Texas ham petrol ve
Borsa İstanbul’daki 20 petrokimya plastik firma hisse senetleri fiyatları
kullanılmıştır. Oynaklık yayılımı için DCC-GARCH modelinden yararlanılmıştır. Portföy
optimizasyonu için petrol ve tüm firmaların ortalama ağırlıkları ve optimal
hedge oranları hesaplanılmıştır. Yapılan analizler sonucunda, petrol ve 11
firma hisse senetleri arasında önemli derecede oynaklık yayılımı mevcuttur. Ayrıca
portföy optimizasyonundan çıkan sonuçlar, optimal bir portföy için petrolün
önemini göstermektedir. Yatırımcılar petrol varlığı yerine daha çok firma hisse
senetlerine yatırım yaparak risklerini minimize edebilirler.
