THE RELATIONSHIP BETWEEN CORPORATE GOVERNANCE AND STOCK RETURNS

Öz

This study investigates the relationship between corporate governance and stock returns both at index and firm-level for the period between 2007 and 2013. The index-level analysis focuses on the long-run relationship between Borsa İstanbul Corporate Governance Index and Borsa İstanbul 100 Index. The firm-level analysis examines the effect of corporate governance ratings on stock returns. The firm-level analysis includes twelve companies which have been listed on Corporate Governance Index from 2007 till 2013. The index-level analysis employs co-integration analysis, while the firm-level analysis calculates cumulative abnormal returns. The results indicate that there is a long-run index-level relationship and also corporate governance rating announcements have an effect on stock returns.
