Vickers Stock Research, a subsidiary of Argus Research Group, tracks and analyzes insider trading and institutional ownership trends. Form 13-Fs are due 45 days after the end of calendar quarters, and are now coming in from 4Q20. We review the 13Fs of the major activist investors, including Carl Icahn, Trian Fund Management, Jana Partners, and ValueAct Holdings, among others. Activist investing has evolved and is now less about generating a short-term return on an underpriced stock and more about achieving long-term returns through an active management/investor partnership. Here are some recent new purchases and key holdings of activist investors, according to Vickers.
