Nonlinear market behavior at the İstanbul stock exchange

Matematiksel ve istatistiki metodlardaki gelişmeler doğrusal olmayan metodların kullanımını artırmıştır.Özellikle borsalarda meydana gelen krizlerden sonra doğrusal olmayan metodların önemi artımş ve hızlı birgelişme göstermiştr. Borsalar yüksek getiri nedeniyle herzaman cazip bir yatırım alanı olurken diğe r yandanöngörülemeyen piyasa hareketleri nedeniyle de riskte çoğunlukla yüksek olmuştur. Bununla birlikte doğrusalomayan yöntemler borsa oyuncularının daha fazla kar elde etmeleri konusunda yardımcı olmuştur. Bu çalışmadaBorsa İstanbul AŞ incelenmiştir. Türkiye fon yöneticileri açısında oldukça cazip bir gelişmekte olan piyasıdır.Bu çalışmanın amacı Borsa İstanbuldaki farklı sektörlerin indekslerini kullanarak doğrusal olmayan bağımlılığıve doğrusal olmamaya neden olan olayları belirlemektir. Bu amaçl a, pencereleme test prosedürünü kullananHinich Portmanteau Bicorrelation parametrik olmayan test kullanılmıştır.

Borsa Istanbul'da doğrusal olmayan piyasa hareketleri

Advances in Mathematical and statistical methods have increased the use of non- linear methods. Especially afterthe stock market crash, the non-linear work has become even more important and gained rapid rate ofdevelopment. Due to the high returns of the stock market stock marketshave always been an attractiveinvestment area. On the other hand it s the unpredictable movements of the stock market makes it more risky.However, non- linear methods help to stock market players to create more revenues. In the study, Turkish capitalmarkets, Borsa İstanbul is examined. Turkey is an attractive emerging market for fund managers. The purpose ofthis paper is to determine the non-linear dependence and events that lead to non- linearity by using the indexes ofdifferent sectors at the Borsa İstanbul. To this end, the Hinich portmanteau bi-correlation non-parametric test thatuses the windowed testing procedure is applied.
