Özet

Varlık fiyatlama modelleri, finans literatüründe yıllardır ilgi çeken bir konu olmuştur. Son dönemde, Hou, Xue ve Zhang (2015) tarafından “q-faktör model” olarak adlandırılan yeni bir varlık fiyatlama modeli geliştirilmiştir. Modelde risksiz faiz oranını aşan getiri, piyasa betası, firma büyüklüğü, yatırım ve karlılık faktörleri ile açıklanmaktadır. Bu çalışmada q-faktör modelinin geçerliliği zaman serisi regresyon yöntemi kullanılarak Borsa İstanbul’da test edilmiştir. GRS-F testi sonuçlarına göre, q-faktör modelinin Borsa İstanbul’da geçerli olduğu bulunmuştur. Elde edilen bulgular, dört faktörün tümünün Temmuz 2009 ile Haziran 2016 döneminde Borsa İstanbul’da fiyatlandığını ve q-faktör modelinin beklenen hisse senedi getirilerini tahminlemede kullanılabileceğini göstermiştir.

Abstract

Asset pricing models are the subject that has attracted much attention in finance for years. Recently Hou, Xue and Zhang (2015) developed a new asset pricing model and denominated “q-factor model”. In the model, the excess returns of risk-free rate are explained by market beta, firm size, investment and profitability factors. In this study, the validity of q-factor model in Borsa Istanbul is investigated by using time series regression method. As per GRS-F test results, it is obtained that q-factor model is valid in Borsa Istanbul. The findings revealed that all four factors are priced between July 2009 and June 2016 in Borsa Istanbul and q-factor model can be used in predicting expected returns.
