This paper investigates the effect of Coronavirus (COVID-19) on Turkey stock market. For this purpose, montly realized volatilities of 23 primary sector indices traded on Borsa İstanbul are calculated for the period of June 2019 to July 2020. After analyzing realized volatility values, it is found that: (1) COVID-19 caused volatility jump for all sector indices in March 2020, when cases in Turkey appeared and increased rapidly; (2) While the most volatility jump occurred in stocks of sports companies due to COVID-19, the least volatility jump occurred in stocks of insurance firms; (3) After March 2020, realized volatility values back to normal for all sector indices and the effect of COVID-19 on Turkey stock market volatility has disappeared. This paper, showing the impact of COVID-19 on the Turkish stock market and the recent state of the markets, is believed to provides important implications for not only investors, portfolio managers, and policymakers, but also for academics in economics and finance, who are all looking to demonstrate economic and financial effects of COVID-19.

Bu çalışma Koronavirüs (COVID-19)’ün Türkiye hisse senedi piyasası üzerindeki etkisini incelemektedir. Bu amaç için, Borsa İstanbul’da işlem gören 23 birincil sektör endeksinin Haziran 2019 ile Temmuz 2020 arasındaki aylık gerçekleşen oynaklıkları hesaplanmıştır. Gerçekleşen oynaklık değerleri analiz edildikten sonra (1) COVID-19’un Türkiye'deki vakaların ortaya çıktığı ve hızla arttığı Mart 2020'de tüm sektör endekslerinde volatilite sıçramasına neden olduğu; (2) En fazla oynaklık sıçramasının spor şirketlerinin hisselerinde görüldüğü, en az oynaklık sıçramasının ise sigorta firmalarının senetlerinde görüldüğü; (3) Mart 2020’den sonra bütün sektör endekslerinin gerçekleşen oynaklık değerlerinin normale döndüğü ve COVID-19’un Türkiye hisse senedi piyasası oynaklığına etkisinin kaybolduğu bulunmuştur. COVID-19’un Türkiye hisse senedi piyasasına etkisini ve piyasanın güncel durumunu gösteren bu çalışmanın, sadece yatırımcılar, portföy yöneticileri ve politika yapıcılar için değil aynı zamanda COVID-19'un ekonomik ve finansal etkilerini göstermek isteyen ekonomi ve finans alanındaki akademisyenler için de önemli çıkarımlar sağlayacağına inanılmaktadır.
