Özet: Research Paper Sovereign credit rating notes and outlook notifications issued by international credit rating agencies play a major role in the economic, financial and commercial position of countries. In this study, the impact of sovereign credit rating and outlook notifications for Turkey which are given by Moody's, Standard & Poor's, and Fitch on financial markets in Turkey has been investigated. In this context, the effects of the related disclosures in 2014-2018, on the daily return of BIST 100 index have been comparatively examined by 12 groups.
