Market Reactions Following Corporate Governance Rating Changes: Evidence from the Istanbul Stock Exchange

Öz:
This study investigates the market reaction to the increases and decreases incorporate governance ratings of public firms quoted at the Borsa Istanbul (BIST), as well as themarket reaction to the increases and decreases in the scores for the subcomponents of the totalratings. The findings suggest that investors react negatively to the announcements of decreases inthe overall corporate governance ratings and the scores for the four subcomponents. On the otherhand, the findings surprisingly suggest that investors also react negatively to the announcements ofincreases in the overall corporate governance ratings and the scores for the subcomponents of theseratings. These findings contradict the expectation that investors would value improvements ingovernance ratings highly based on the assumption that increases in these ratings would implyimproved corporate governance that would lead to decreased agency costs and therefore, increasedfirm value. The findings are robust to various econometric specifications and tests.

Kurumsal Yönetim Derecelendirme Notu Değişiklikleri Sonrası Piyasa Tepkisi: Borsa İstanbul Örneği

Öz:
Bu çalışmada, Borsa İstanbul (BIST)’da işlem gören halka açık şirketlerin kurumsal yönetim derecelendirme notlarında ve ayrıca toplam derecelendirme notunu oluşturan alt bileşen puanlarında meydana gelen artışlara ve azalışlara yönelik piyasanın tepkisi incelenmiştir. Çalışma bulguları, yatırımcıların toplam kurumsal yönetim derecelendirme notlarındaki ve dört alt bileşenin puanlarındaki düşüşlere olumsuz tepki verdiklerini göstermektedir. Diğer taraftan, bulgular beklenenin aksine, yatırımcıların toplam kurumsal yönetim derecelendirme notlarındaki artışların ve bu notu oluşturan alt bileşen puanlarındaki artışlara da olumsuz tepki verdiklerine işaret etmektedir. Bu sonuçlar, yatırımcıların kurumsal yönetim derecelendirme notlarındaki artışların kurumsal yönetimi geliştirdiği ve vekalet maliyetlerini düşürerek, firma değerinin artmasına yol açacağı varsayımına dayanan beklentisiyle çelişmektedir. Bulguların doğruluğu çeşitli ekonometrik yöntemler ile test edilmiştir.
