Abstract

Bu çalışmada Türkiye’de Merkezi Kayıt Kuruluşu (MKK) tarafından haftalık bazda yayınlanan ve finansal istikrar ölçüsü olarak kabul edilen, yerli ve yabancı yatırımcılara ait risk iştahı verilerinin tahmin edilebilirliği incelenmiştir. 2008 - 2013 dönemlerindeki verilerin incelendiği çalışmada ADF, KPSS gibi birinci nesil birim kök testlerinin yanında yapısal kırılmayı dikkate alan Lee ve Strazicich (2003) testi ile Caner ve Hansen (2001) eşikli birim kök testi gerçekleştirilmiştir. Çalışmadan elde edilen sonuçlar yerli yatırımcılara ait risk iştahı verilerinin doğrusal olduğunu ve eşik etkisinin olmadığını ortaya koymaktadır. Yabancı yatırımcılara ait risk iştahı serisinin ise doğrusal olmadığını ve eşik etkisinin var olduğu tespit edilmiştir. Ayrıca yabancı yatırımcılara ait risk iştahının düşme eğiliminde olduğu dönemlerde tahmin edilebildiği, artma dönemlerinde ise tahmin edilemediği ortaya konulmaktadır.
