UnitedHealth Group Just Hit a 52-Week High. Is It Too Late to Buy This Soaring Stock?

UnitedHealth Group has rebounded to a 52-week high with a 23% gain year-to-date, driven by better-than-expected Medicare Advantage reimbursement rates and improved margins. However, the stock remains down 34% from two years ago. The company faces significant dependency on government funding, with 44% of revenue from Medicare and Medicaid, creating uncertainty about future profitability if reimbursement rates decline.
