Abstract

This study aims to investigate the correlation and the spillover effects between Central and East European (CEE) Countries’ stock markets during the Covid-19 Pandemic Period. CEE countries are listed as Bulgaria, Croatia, the Czech Republic, Hungary, Poland, Romania, the Slovak Republic, Slovenia, Estonia, Latvia, and Lithuania by OECD. The data set was obtained from the Bloomberg data services and includes 308 observations of daily returns between March 11th, 2020 and August 1st, 2021. As a result of the empirical analysis using the Pearson Correlation, the Multivariate VAR Model, and the Granger Causality Test, a high correlation was found between the stock markets of CEE countries, and 15 causality relationships were determined. The analysis also revealed bidirectional relationships between the Bulgaria Stock Exchange Index and Romania Bucharest Stock Exchange Index, the Polish Warsaw Stock Exchange Index and Croatia Zagreb Stock Exchange Index, the Romania Bucharest Stock Exchange Index and Bulgaria Stock Exchange Index, and the Croatia Zagreb Stock Exchange Index and Polish Warsaw Stock Exchange Index. High correlation and causality relationships, which are also supported by impulse-response and variance decomposition test results, reveal that there is a spillover effect between the stock markets of CEE countries.

COVID-19 Pandemi Döneminde Hisse Senedi Piyasalarının Yayılma Etkileri: Orta ve Doğu Avrupa Ülkeleri Kanıtları

Abstract

Bu çalışmanın amacı, OECD tarafından Orta ve Doğu Avrupa ülkeleri olarak adlandırılan; Bulgaristan, Hırvatistan, Çek Cumhuriyeti, Macaristan, Polonya, Romanya, Slovak Cumhuriyeti, Slovenya, Estonya, Letonya ve Litvanya ülkelerinin hisse senedi piyasaları arasındaki korelasyonu ve piyasalar arasındaki yayılma etkisini araştırmaktır. Bu çalışmada kullanılan veriler, 11 Mart 2020 - 1 Ağustos 2021 tarihleri arasındaki 308 güne ait hisse senedi getirilerini içermektedir. Veriler, Bloomberg veri servislerinden elde edilmiştir. Pearson Korelasyonu, çok değişkenli VAR modeli ve Granger Nedensellik testi kullanılan çalışma sonucuna göre; hisse senedi piyasaları arasında yüksek korelasyonlar ve 15 adet nedensellik ilişkisi tespit edilmiştir. Bu sonuçlara ilave olarak, Bulgaristan Menkul Kıymetler Borsası Endeksi ile Romanya Bukres Menkul Kıymetler Borsası Endeksi, Polonya Varşova Menkul Kıymetler Borsası Endeksi ve Hırvatistan Zagrep Menkul Kıymetler Borsası Endeksi, Romanya Bukres Menkul Kıymetler Borsası Endeksi ve Bulgaristan Menkul Kıymetler Borsası Endeksi, Hırvatistan Zagrep Borsa Endeksi ve Polonya Varşova Menkul Kıymetler Borsası Endeksi arasında çift yönlü bir nedensellik ilişkisi olduğu ortaya konulmaktadır. Etki-tepki ve varyans ayrıştırma testleri sonuçları ile desteklenen yüksek korelasyon ve nedensellik ilişkileri, Orta ve Doğu Avrupa ülkeleri borsaları arasında yayılma etkisi olduğunu ortaya koymaktadır.
