Insurance giant UnitedHealth Group Inc. (NYSE:UNH) stock is surging on Thursday. Over the last six months, the stock has gained almost 20%.

Bank of America Securities (BofA) on Thursday upgraded UnitedHealth from Neutral to Buy and raised the price forecast from $420 to $450.

The stock came under pressure in January as investors reacted to a proposed near-flat Medicare Advantage rate update from federal regulators and digested UnitedHealth’s fourth-quarter 2025 earnings and fiscal 2026 outlook.

Medicare Advantage Rate Changes Shift Investor Sentiment

In January, the Centers for Medicare & Medicaid Services proposed a net average payment increase of just 0.09% for Medicare Advantage plans, well below industry expectations of 4% to 6%. The proposal was expected to generate only about $700 million in additional payments for insurers.

Investor sentiment improved sharply in April after regulators finalized the calendar year 2027 Medicare Advantage rate announcement.

The final update called for a 2.48% payment increase, translating to more than $13 billion in additional funding for Medicare Advantage plans and sparking a rally in managed-care stocks, including UnitedHealth.

AI-Driven UnitedHealth Earnings Potential

On Thursday, a BofA analyst wrote that UnitedHealth could lead a broader managed care rally if healthcare utilization trends continue to moderate.

The analyst added that improving medical cost trends and supportive near-term data points position the company for a favorable second-quarter earnings report.

On eased medical costs, UnitedHealth raised its fiscal 2026 adjusted earnings per share from over $17.75 to more than $18.25 compared to the consensus of $17.86.

Morgan Stanley also raised its price forecast on UnitedHealth to $453 from $395 on Thursday and maintained its Overweight rating. The analyst noted that managed care stocks have been trending higher amid early signs of easing utilization trends.

Morgan Stanley also highlighted potential AI-driven benefits for managed care organizations, saying improvements across both revenue generation and cost efficiency could result in roughly 45% average earnings upside.

In May, Berkshire Hathaway (NYSE:BRK) (NYSE:BRK) liquidated its entire position in the U.S. insurance giant.

UNH Stock Price Activity: UnitedHealth Group shares were up 5.14% at $396.39 at the time of publication on Thursday, according to Benzinga Pro data.
