İMKB'de yabancı işlemleri ve hisse senedi getirileri ilişkisi

Bu çalışmada, İMKB hisse senedi piyasasında yabancılar tarafından gerçekleştirilen işlemlerin hisse senedi getirileri üzerinde etkili olup olmadığı, tabanın genişlemesi (base broadening) hipotezinden yola çıkılarak ortaya konulmaya çalışılmıştır. 1997:01 - 2009:12 tarihleri arasındaki aylık veriler kullanılarak, iki değişken arasındaki eşbütünleşme ilişkisi Pesaran ve diğerleri (2001) tarafından geliştirilen Sınır Testi ve ARDL modelleri yardımıyla analiz edilmiştir. Sonuçta yabancı işlem hacmi ile hisse senedi getirileri arasında uzun dönemde pozitif bir ilişki tespit edilmiş ancak bu ilişkinin kısa dönemde anlamlı olmadığı görülmüştür. Bu bulgular İMKB'de tabanın genişlemesi hipotezinin uzun dönemde geçerli olduğu şeklinde yorumlanabilir.

The relationship between foreign investments and stock returns on ise

This paper, emerging from base broadening hypothesis, investigates whether the foreign transactions have an affect on the security returns in ISE. The cointegration relationship between two variables has been analyzed by the bounds testing approach developed by Pesaran et. al.(2001) and ARDL models using the monthly data of 1997:01- 2009:12. As a result, a positive relationship has been detected between the foreign transactions and returns of shares in the long run. However, the same relationship is insignificant in the short run. This finding can be interpreted as the validity of base broadening hypotesis in long term in ISE.
