Abstract

Geleneksel finans teorileri finansal piyasalarda finansal yatırımcının her zaman rasyonel davrandığını, yatırım kararlarında getirisini maksimize edecek kararlar verdiğini, tam bilgiye sahip olduğunu, piyasada işlem maliyetlerinin olmadığını varsaymaktadır. Piyasalarda tüm bilgi finansal varlık fiyatlarına hızla yansımakta, varlık fiyatları gerçek değerini yansıtmakta, normalin üzerinde getiri fırsatı oluşmamaktadır. Bu piyasa etkinliğiyle tanımlanmakta ve Etkin Piyasalar Hipotezi ile açıklanmaktadır. Fakat geleneksel teoriler piyasalardaki finansal yatırımcıların yatırım kararları nedeniyle oluşan anormal varlık fiyatlarını açıklamakta yetersiz kalmaktadır. Bu nedenle açıklanmakta güçlük çekilen finansal krizler, fiyat anomalileri yatırımcı davranışını da dikkate alan davranışsal finans yaklaşımıyla daha iyi açıklanmaya çalışılmaktadır.

Çalışmada BIST30 Endeks getirisinden hesaplanan ±4 standart sapma değerleri ile tespit edilen örneklem olarak seçilen haberlerin BIST30 Endeks pay senetleri yatırımcısı üzerindeki etkileri Olay Analizi Yöntemi ile araştırılmaktadır. Analiz sonuçları BIST30 Endeksinde haber etkisi sonucu anormal getiri oluştuğunu ve piyasanın yarı güçlü formda etkin olmadığını göstermektedir. BIST30 Endeks pay senetlerinde olumlu haber etkisi sonrası negatif trend başlarken, olumsuz haber etkisi sonrasında ise pozitif trend başlamaktadır. Ayrıca demografik olarak Isparta ilindeki yatırımcı verileri analiz edildiğinde 40 yaş altı daha çok sayıdaki yatırımcı, daha küçük değerdeki portföylerle piyasada işlem yaparken, 40 yaş üstü daha az sayıdaki yatırımcı daha büyük portföylerle yatırım yapmayı tercih etmektedir.

Thanks

Hocam, yardımınız ve ilginiz için çok teşekkür ederim, Saygılarımla
