The effect of volatility spillovers that affects financial markets is a very important situation for the participants in the market. When the volatility in one market affects the other market, the risk occurs. In this situation, portfolio managers and investors will want to minimize this risk in order to protect their portfolios. This study aims to analyse volatility spillover between BIST Services and BIST Financial sector indices of Borsa İstanbul. In addition, with the Granger and Hong Causality tests to be used, the direction and relationship of causality between the two sector indices were revealed. As a result of the analyses, it was determined that there was volatility spillover between the two sector indices. According to the results of causality analysis tests, it was shown that there was a bivariate causality relationship between the two sector indices. The results are important for both investors and portfolio managers to reduce their risks and to ensure optimal portfolio management.

Oynaklıkların yayılma etkisi,
finansal piyasaları etkileyen ve piyasadaki katılımcılar açısından oldukça
önemli hal alan bir durumdur.  Bir
piyasada yaşanan oynaklık diğer piyasayı etkilemesi halinde risk oluşmaktadır.
Bu durumda portföy yöneticileri ve yatırımcılar portföylerini korumak için bu
riski minimize etmek isteyeceklerdir. Bu çalışmada Borsa İstanbul’un BIST Hizmetler
ve BIST Mali sektör endeksleri kullanılarak aralarındaki oynaklık yayılımı
analiz edilmiştir. Ayrıca kullanılacak olan Granger ve Hong Nedensellik
testleri ile iki sektör endeksi arasındaki nedenselliğin yönü ve ilişkisi
ortaya konulmuştur. Yapılan analizler sonucunda her iki sektör endeksleri
arasında oynaklık yayılımının olduğu belirlenmiştir.  Nedensellik analizleri testleri sonucuna göre
her iki sektör endeksleri arasında çift yönlü bir nedensellik olduğu
görülmüştür. Elde edilen sonuçlar gerek yatırımcılar gerekse portföy
yöneticileri açısından risklerini azaltmak ve optimal portföy yönetimi yapmak için
önemli olmaktadır.
