Küresel Ekonomi Politika Belirsizliğinin Borsa İstanbul’da İşlem Gören Seçilmiş Endeks Getirileri Üzerindeki Etkisi

Abstract

Küresel demokratik karar alma mekanizmalarında yaşanan belirsizlik, dünya ülkelerinin ekonomik sonuçlarının oynak bir yapıda gerçekleşmesine sebep olmakta ve yatırımcıların ekonomilere güvenini olumsuz yönde etkilemektedir. Bu çalışmanın amacı, küresel ekonomi politika belirsizliğinin Borsa İstanbul’da işlem gören şirketlerin getirileri üzerindeki etkisini oynaklık modelleriyle tespit etmektir. Bu doğrultuda çalışmada 1997:1-2018:4 dönemine ilişkin veriler kullanılmıştır. Çalışmada, aylık küresel ekonomi politika belirsizlik endeksi ile BIST Elektrik, BIST Kimya, Petrol, Plastik, BIST Metal Ana ve BIST Sınai Getiri Endeksleri ele alınmıştır. BIST Elektrik, BIST Kimya, Petrol, Plastik Getiri Endeksleri ile BIST Metal Ana Getiri Endeksi serileri için tahminlenen oynaklık model tahmin sonuçlarına göre, küresel ekonomi politika belirsizliğinin ilgili sektörlerde işlem gören şirketlerin hisse senetlerinin getirilerindeki oynaklık üzerindeki etkisinin istatistiksel açıdan anlamlı ve pozitif olduğu tespit edilmiştir.
