UnitedHealth Stock Watches Berkshire Exit, Optum AI Effort
Berkshire Hathaway sold its entire UnitedHealth Group stake in the first quarter, less than a year after buying 5.04 million shares. UnitedHealth shares closed at $393.85 Friday, down 1.3%. Bloomberg reported UnitedHealth is tracking some Optum workers’ use of AI tools as it expands technology in operations. Analysts say insurers need another quarter of clean medical-cost data before judging recovery.
