Investors’ reaction to litigation announcements by Capital Markets Board of Turkey

I empirically investigate investors’ reaction to the litigations announcements published by Turkish Capital Markets Board (CMB). I use event study to analyze daily abnormal returns for significant market reactions. I compile a litigation announcements sample that spans 202 events of 145 unique stocks between January 20, 2012 and January 3, 2019. My findings show that investors perceive litigations announcements as bad news. Statistically significant negative responses happen both on event day and two days after, hinting difference in investor behavior. I find that the negative reaction to the news are significantly higher for corporations announcements than they are for individual announcements. The negative reaction is significantly higher for indictments announcements than they are for administrative fees.
