Hedge fund activism is a topic of increasing importance among scholars and policy-makers. In the post-financial crisis time period, hedge fund activist interventions at target companies have generated extensive discussion and policy debate, but activism in this time period has not yet been studied in a systematic way. This paper examines recent hedge fund activism using a hand-collected data set regarding 1,262 interventions by hedge fund activists from 2008 through 2014. We find that hedge fund activism continues to generate positive announcement–period abnormal stock returns, and that these returns vary significantly based on which hedge funds are involved. In particular, we find that hedge fund activists involved in the largest interventions in terms of aggregate market capitalization generate the largest abnormal returns, whereas hedge fund activists involved in more frequent, but smaller, interventions generate smaller returns. We create a new measure of hedge fund reputation based on these findings.
