Abstract

Belirsizlik olgusu geleceğin bilinmezliğinin yarattığı bir olgudur. Ekonomik unsurların tam olarak öngörülmesi tam piyasa etkinliği olarak tanımlanırken, gerek siyasal, gerekse doğal öngörülemez olgular ekonomik unsurlarda belirsizliği ve dolayısıyla öngörülemezliği doğurmaktadır. Risk unsuru yatırımcı için hem yüksek kazanç hem de büyük zarar etme anlamı taşıyabilmektedir. ABD ekonomisi bazlı olarak Baker vd. tarafından geliştirilen belirsizlik endeksi küresel ölçekte de yatırımcılar için pozisyon alma imkanı sunduğu gözlenmektedir. Çalışmada belirsizlik endeksi ile Borsa İstanbul100 endeksi arasındaki ilişkiler simetrik ve asimetrik boyutta araştırılmıştır. Araştırma sonuçlarına göre iki değişken arasında simetrik ilişkiler yakalanamamış iken, asimetrik ilişkilerin var olduğu tespit edilmiştir. Asimetrik ilişkilerde uzun dönemde belirsizlik endeksindeki pozitif ve negatif şokların borsa endeksini ters yönde etkilediği görülmüştür. Buna göre belirsizlikte artışlar borsadan çıkışları tetikleyerek farklı yatırım araçlarına doğru ikame etkisi doğurmaktadır. Diğer bir ifadeyle küresel olumsuzluklar yayılma etkileri ile BİST100’ü de olumsuzlaştırmaktadır. Diğer taraftan küresel ölçekte belirsizlikte iyileşmeler ise borsaya olumlu katkılarda bulunmaktadır.

Investigation on Linearity or not Linearity of the Relationships between Stock İstanbul and Uncertainty Index (1998:01-2018:12)

Abstract

The phenomenon of uncertainty is a phenomenon created by the unknown of the future. While the full prediction of economic factors is defined as full efficient market, both political and natural unpredictable phenomena lead to uncertainty in economic factors and thus unpredictability. The risk factor can have both high profit and great loss for the investor. The uncertainty index and based on the US economy developed by Baker et al. provides investors with the opportunity to take positions on a global scale. In the study, the relationship between uncertainty index Stock İstanbul 100 index was investigated on symmetric and asymmetric dimensions. According to the results of the study, symmetrical relations between two variables could not be detected, but asymmetric relations were found. In asymmetric relations, positive and negative shocks in the uncertainty affect the stock index in the long run. Accordingly, the increase in uncertainty creates a substitution effect towards different instruments by triggering exits from the stock market. In other words, global adversities negate BİST100 with diffusion effects. On the other hand, improvements on a global scale contribute positively to the stock market.
