US Activist Hedge Fund Institutional SEC 13D 13G — July 31, 2026
The July 31, 2026 filings reveal a significant divergence in institutional and activist activity. Vanguard Capital Management made a broad, passive push across 25+ companies, crossing the 5% threshold in 16 names (e.g., Compass, Anavex, Conagra) while reducing or exiting positions in 8 others (e.g., Associated Banc-Corp, Chatham Lodging), signaling a portfolio rotation. Activist activity is concentrated in Scully Royalty Ltd., where the Kellogg group (35.5% stake) and Neil Subin (13.0%) are engaged in a proxy fight and litigation over the 2025 AGM, creating a high-stakes control battle. Capital World Investors maintained its 34.9% stake in Diebold Nixdorf, while RA Capital executed a strategic exchange of shares for pre-funded warrants at Inhibikase Therapeutics to cap ownership at 9.99%. Insider selling is notable at Sanara MedTech (complete exit by Tall Pines Capital) and Diana Shipping (stake fell below 5%). The overall theme is one of passive rebalancing by Vanguard, mixed with targeted activist pressure and strategic positioning by specialized funds.
