So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

BIST Sektör Endekslerinin Zamanla Değişen Beta Katsayıları
2022

Author:  
Abstract:

Çalışmanın amacı BIST’te yer alan 21 adet sektör endeksinin zamanla değişen beta katsayılarının hesaplanmasıdır. Analizler sonucunda 21 adet sektör endeksinin beta katsayılarının zamanla değişen bir yapıda olduğu gözlenmiştir. Aynı zamanda zamanla değişen tüm sektör betalarının ortalamaya dönme eğilimde olduğu belirlenmiştir. Çalışmada en oynak beta katsayı XFINK endeksine ait iken, en az oynak beta katsayısı XSPOR endeksine ait olduğu tespit edilmiştir. Ayrıca çalışmada ortalama olarak en düşük beta katsayısı 0.490 ile XSPOR endeksine ait iken en yüksek beta katsayısı ise 1.248 ile XBANK endeksine ait olduğu saptanmıştır. Çalışmada, sektör endekslerinin betası zamanla benzer değişimlere sahip olduğu tespit edilmiştir.

Time-varying Beta Coefficients Of Bist Sector Indices
2022
Author:  
Abstract:

The aim of the study is to calculate the time-varying beta coefficients of 21 sector indices in BIST. As a result of the analysis, it has been determined that the beta coefficients of 21 sector indices have a structure that changes over time. At the same time, it has been found that all sector time-varying betas tend to mean reversion. In the study determined that the most volatile beta coefficient belongs to the XBANK index, while the least volatile beta coefficient belongs to the XILTM index. In addition, in the study determined that the lowest beta coefficient with 0.441 belonged to the XTCRT index, while the highest beta coefficient was found to belong to the XBANK index with 0.868. In the study, it has been determined that the beta of other sector indices has similar changes over time, except for the XELKT, XILTM, and XSPOR indices.
