ETKİN PORTFÖY YÖNETİMİNDE PİYASA ORTALAMALARININ KULLANIMI

Year 2000, Volume: 16 Issue: 1, 595 - 613, 01.12.2000

Abstract

Bu çalışmada aritmetik ve geometrik ortalamanın taşıdığı en­formasyonun farklı olduğu şeklinde ifade edilebilecek hipotezin geçerliliğini araştırabilmek için sermaye piyasasında en yüksek getiriyi sağlama amacına dönük bir işlem stratejisi geliştirilmektedir. Sözü edilen iki tür ortalamanın esas alınması ile oluşturulan hisse senedi fiyat indeksleri arasında eşbütünleşik bir ilişkinin reddedilmesi yuka­rıda sözü edilen hipotezi destekler nitelikte bir kanıt olarak kabul e­dilmektedir. Geliştirilen stratejinin uygulanması ile elde edilebilecek aşırı getirinin süreklilik göstermesi beklenemez. Bu nedenle otoregresif doğrusal model ve yapay ağ modeli aracılığı ile söz konusu ortalamalar tahmin edilmiş ve gerçekleştirilen tahminlerin kullanılma­sı ile desteklenen işlem stratejisi al-tut stratejisi ile karşılaştırılarak ortalama getirinin daha yüksek olduğu sonucuna ulaşılmıştır.
