US Activist Hedge Fund Institutional SEC 13D 13G — July 15, 2026
The July 15, 2026 batch of 50 filings reveals a dominant theme of passive institutional accumulation, particularly by Bank of Nova Scotia (BNS) and Pzena Investment Management, across diverse sectors including crypto-mining (CleanSpark, TeraWulf), defense tech (Voyager Technologies), and legacy manufacturing (Magna, Hooker Furnishings). Pzena has emerged as a significant, high-conviction holder, establishing or increasing stakes above 8% in six companies (Magna, Globant, Hooker, Amdocs, Corebridge, ScanSource), signaling a value-oriented thesis on these names. The most critical development is Warren Buffett's massive charitable donation of 9 million Berkshire Hathaway B-shares, a planned transfer that reduces his economic stake but maintains voting control. A notable activist development is the cooperation agreement at Repay Holdings, where a 9.38% holder secured a board seat, while Rayonier Advanced Materials is in play with a formal strategic alternatives process drawing interest from AIP. Several micro-cap filings (Vivos, Newton Golf, Elong Power) feature complex capital structures with beneficial ownership blockers, indicating high-risk, structured investments. Overall, the digest points to a market where large passive managers are rotating capital into mid-cap value, while select special situations (M&A, board fights) offer event-driven opportunities.
