Vickers Stock Research, a subsidiary of Argus Research Group, tracks and analyzes insider trading and institutional stock ownership trends. Form 13-Fs, which institutions must file to report their holdings, are due 45 days after the end of calendar quarters, and have now come in from 1Q26. We like to review the 13Fs of major activist investors -- including Carl Icahn, Trian Fund Management, Jana Partners, Starboard Value and ValueAct Holdings, among others -- in order to determine their core holdings and new purchases.

Activists have made progress in the past year, with high-profile investments into blue-chip companies such as Fedex and Union Pacific. Here are some recent new purchases and key holdings of activist investors, as well as other high-profile money managers.
