Abstract

This study aims at investigating whether Capital Asset Pricing Model (CAPM) is applicable in the İstanbul Stock Exchange Market. The risk-return structure of Turkish stocks is analyzed by testing the CAPM with Fama-MacBeth’s two-stage approach, a combination of both time series and cross section estimation. The time period covered is between 1991-1998. The findings suggested that there is no significant relationship between the return of portfolios and betas. Residual risk is also insignificant as we expected. In general, the results of the study indicate that CAPM cannot be used as a predictive model in Turkish Equity Markets.

Özet

Bu çalışmada İstanbul Menkul Kıymetler Borsası(İMKB)’nda Sermaye Varlıkları Modeli(CAPM)’nin geçerli olup olmadığı araştırılmış-tır. Bu amaçla zaman serisi analizi ile kesit modellerine dayanan Fama-MacBeth’in iki aşamalı yaklaşımı kullanılmıştır. Çalışma, 1991-1998 yıllarını kapsamıştır. Araştırma bulgularına göre İMKB’de portföylerin getirileri ile betaları arasında hiçbir ilişki bulunmadığı anlaşılmıştır. Ancak firma riski beklenildiği gibi önemsizdir. Çalışmanın sonucunda, CAPM’in Türkiye’de hisse senetleri piyasasında bir öngörü modeli olarak kullanılamayacağı ortaya konulmuştur.
