İSTANBUL MENKUL KIYMETLER BORSASI’NDA ETKİN PİYASA HİPOTEZİNİN UZUN HAFIZA MODELLERİ İLE ANALİZİ: SEKTÖREL BAZDA BİR İNCELEME

Bu çalışmada İstanbul Menkul Kıymetler Borsası’nda (İMKB) etkin piyasa hipotezinin geçerli olup olmadığı parametrik ve yarı parametrik yöntemler ile araştırılmıştır. Zayıf formda etkin piyasa hipotezinin varlığını belirleyebilmek için 10 sektör endeksi dikkate alınmıştır. Yarı parametrik ve parametrik uzun hafıza model sonuçları sektörlere ait endeks getirilerinin oynaklığının uzun hafıza özelliği gösterdiğini belirtmektedir. Buna bağlı olarak İMKB’nin etkin bir piyasa olmadığı ifade edilebilir
