Overview

• Berkshire Hathaway’s Form 13F filing revealed a roughly 5 million-share position in UnitedHealth valued at $1.6 billion, triggering a 13.9% intraday gain and the insurer’s strongest weekly rally in years.
• Other major investors such as George Soros’s firm, Michael Platt’s BlueCrest and David Tepper’s Appaloosa also built new or larger UnitedHealth stakes during the second quarter.
• UnitedHealth continues to navigate rising medical costs, a federal Department of Justice probe, the fallout from a cyberattack and the fatal shooting of an insurance-unit executive.
• The company has missed Wall Street earnings targets for two consecutive quarters and reinstated a weaker 2025 outlook, underscoring persistent financial pressure.
• In the same quarter, Berkshire reallocated capital into homebuilders Lennar and D.R. Horton and steelmaker Nucor while trimming stakes in legacy technology and financial holdings.
