Oynaklık yayılımı etkisi finansal piyasa katılımcıları için her zaman cazip bir konu olmuştur. Bu çalışma çok değişkenli GARCH modelini kullanarak Borsa İstanbul’daki BIST Mali ve BIST Hizmetler olan iki önemli sektör endeksi arasındaki oynaklık yayılımını araştırmayı amaçlamaktadır. İki sektör arasındaki nedensellik ilişkisini belirlemek için Granger ve Hong’un Nedensellik testleri kullanılmıştır. 4 Ocak 2010’dan 24 Temmuz 2018’e kadar kapsayan iki önemli sektör endekslerini incelemenin ardından, bulgular BIST Mali ve BIST Hizmetler sektör endeksleri arasında oynaklık yayılımı olduğunu göstermiştir. Nedensellik analizlerine gelince, hem Granger nedensellik hem de Hong’un nedensellik testlerinin sonuçlarına göre iki sektör endeksi arasındaki oynaklık yayılımı iki yönlü nedensel ilişkiyi göstermiştir. Sonuçlar, en uygun varlık tahsisi ve portföy yönetimi yapmak için, piyasa katılımcıları ve yatırımcılar açısından büyük önem arz etmektedir.

The volatility spillover effect has always been an attractive issue for financial market participants. This research aims to investigate volatility spillover between two major sector indexes, namely BIST Financial and BIST Services of Borsa Istanbul by using a multivariate GARCH model. Granger causality and Hong’s causality tests were used to determining causal relation between them. Examining two major sector indexes from January 4, 2010, to July 24, 2018, the findings indicated that there was volatility spillover BIST Financial and BIST Services sector indexes. As for causality analyses, the volatility spillover between two sector indexes indicated bivariate causal relation in accordance with both the results of the Granger causality and Hong’s causality tests. The findings are of great importance for market participants and investors to make properly asset allocation and optimal portfolio management.
