Kurumsal yönetim derecelendirme notu açıklamalarının hisse senedi getirileri üzerindeki etkisinin incelenmesi

Çalışmanın amacı, beş bankaya ve bir katılım bankasına ait kurumsal yönetim derecelendirme notu açıklamalarının hisse senedi getirileri üzerindeki etkisinin incelenmesidir. Çalışmada olay çalışması yönteminden yararlanılmıştır. Bu çerçevede, 2011 yılında yapılan kurumsal yönetim derecelendirme notu açıklamaları olay günleri olarak belirlenmiş ve buna bağlı olarak olay gününün beş gün öncesi ve beş gün sonrası dikkate alınarak olay penceresi oluşturulmuştur. Analiz sonuçları, kurumsal yönetim derecelendirme notu açıklamalarının hisse senedi getirileri üzerinde önemli bir etkiye sahip olmadığını göstermektedir.
