Overview

• Berkshire’s late Q2 filing shows it accumulated more than 5 million UnitedHealth shares valued at about $1.6 billion.
• UnitedHealth’s stock climbed roughly 6 percent in extended trading after the disclosure.
• The insurer continues to face a near-50 percent year-to-date share decline, a Justice Department Medicare-billing probe, a withdrawn earnings outlook and CEO Andrew Witty’s departure.
• The holding’s modest size versus Berkshire’s roughly $300 billion equity portfolio indicates portfolio managers Todd Combs or Ted Weschler likely executed the purchase.
• SEC filings also reveal small new stakes in Nucor, Lamar Advertising and Allegion alongside re-entries in Lennar and D.R. Horton.
