UnitedHealth Shares Fall After Berkshire Dumps Entire Stake

UnitedHealth Group UNH shares slid as much as 1% on Monday after Berkshire Hathaway said it had exited its stake in the health insurer, less than a year after rebuilding the position.

Berkshire first built a holding in UnitedHealth in 2006 and later trimmed it several times before reducing the stake to zero in the latest reporting period. The conglomerate returned to the stock in the second quarter of 2025, buying about 5.04 million shares during a steep selloff.

UnitedHealth traded between about $255 and $358 in the first quarter of 2026, a stretch that left the stock down 18%. It closed at $270.59 on March 31 before rebounding in the following weeks.

UnitedHealth later climbed toward $400 after first-quarter earnings topped expectations, Medicare reimbursement rates improved and guidance came in better than feared.
