Abstract

Çin’de ortaya çıkan ve hızla dünyaya yayılan korona virüs (Covid-19) ve bu virüse yönelik geliştirilen aşı haberleri birçok ülke ve sermaye piyasası ile birlikte Borsa İstanbul sektör endekslerini de etkilemiştir. Bu çalışmada, Dünya Sağlık Örgütü (DSÖ)’nün pandemi ilanı ve Türkiye’de ilk vaka, Türkiye’de ilk ölüm ve Türkiye’ye ilk aşı geliş haberlerinin Borsa İstanbul sektör endeksleri üzerindeki etkisi günlük veriler kullanılarak olay etüdü yöntemi ile incelenmiştir. Analiz sonucunda ilk olay günü ve ikinci olay gününün sektörler üzerinde çoğunlukla anormal kayıplara, üçüncü olay gününün ise sektörler üzerinde pozitif anormal getirilere neden olduğu tespit edilmiştir. Haberler neticesinde en çok anormal getiri ve kayıpların yaşandığı sektörün turizm olduğu belirlenmiştir.
