Abstract

Finans literatüründe piyasaların etkinliği, piyasaların tüm bilgiyi fiyatlara yansıtacağı ve yatırımcıların normalüstü getiri elde edemeyeceği varsayımı uzun süredir tartışılmaktadır. Bu çalışmada Etkin Piyasa Hipotezinin varlığı, Türkiye piyasasının temel göstergesi konumunda olan BİST 100 endeksi üzerinde test edilmiştir. Çalışmada gerçekleştirilen ADF, PP ve KPSS birim kök testlerini desteklemek, Türkiye’yi etkileyen şokların BİST 100 endeksini etkileyip etkilemediğini incelemek için yapısal kırılmalı birim kök analizi gerçekleştirilmiştir. Zivot-Andrews testi, modellerin yapısına göre farklı dönemlerde kırılmalar gerçekleştiğini tespit etmiştir. Bu kırılmalar 2002, 2008 ve 2018 yıllarında olmasına rağmen, serilerin durağan bir yapıda olmasını sağlamamıştır. Durağan olmayan seriler birim kök içermektedir, yani piyasa zayıf formda etkin değildir. BİST 100 endeksi üzerinde gerçekleştirilen ADF, PP ve KPSS testleri ve yapısal kırılmalı Zivot-Andrews testi sonuçları birbirini destekler nitelikte olup, endeksin zayıf formda etkin olmadığı sonucuna ulaşılmıştır.
