Overview

• Berkshire quietly built a 5 million-share UnitedHealth position valued at about $1.6 billion using SEC confidentiality before revealing it in its Q2 13F filing.
• UnitedHealth stock surged over 10 percent in extended trading on the filing, lifting sentiment across major health insurers.
• The same disclosure identified new or larger stakes in Nucor, D.R. Horton, Lennar, Lamar Advertising and Allegion.
• Berkshire further trimmed legacy holdings by exiting T-Mobile and reducing stakes in Apple and Bank of America.
• The UnitedHealth bet accounts for roughly 0.6 percent of Berkshire’s equity portfolio and its small size leaves unclear which of Buffett’s investment lieutenants placed the trade.
