Should you buy UnitedHealth stock after UNH soars 9% in a day

Though it remains far below its historic highs, the stock of UnitedHealth (NYSE: UNH) achieved a notable climb during the April 6 session as it rose 1.48% from the previous closing price of $277.26 to its latest closing price of $281.36. Subsequently, the UNH shares rally was turbocharged as the equity rocketed 7.74% after-hours to $303.15.

The large rally follows a Monday, April 6, U.S. government announcement that it would be adjusting payments to private providers of Medicare Advantage plans to improve ‘accuracy.’

Overall, the rise is expected to amount to 2.48% with an added 2.5% from changes to risk assessment payments linked to health status, meaning it will average near 5%. In terms of USD value, the alterations are expected to lead to approximately $13 billion in payments to Medicare Advantage plans in 2027.

Other major healthcare stocks, such as Humana (NYSE: HUM) and CVS (NYSE: CVS), also rallied approximately 13% and 6.72% across the regular and extended sessions, respectively.

Is UnitedHealth stock a ‘Buy’ after 9% upsurge?

For investors, the decision reached by the U.S. government has suddenly made UnitedHealth stock a far more attractive trade. Not only is the company now expected to receive additional billions for its plans, but the April 6 and 7 market activity might have broken a protracted downtrend the equity has been suffering from.

Indeed, if the latest extended session is excluded, UNH shares are 16.36% down year-to-date (YTD) and are trading more than 50% below their 2024 highs near $600.

Simultaneously, the Monday announcement serves to reinforce the prevailing bullish attitude on Wall Street. Even before any notes referencing the 2027 payments are issued, UnitedHealth boasts an overall ‘Strong Buy’ rating on the stock analysis platform TipRanks and an average $368.15 12-month price target.

The equity was also endorsed in the second quarter (Q2) of 2025 by Warren Buffett as Berkshire Hathaway (NYSE: BRK.B) made a substantial purchase of UNH shares. 

Interestingly, ‘The Oracle of Omaha’s’ UnitedHealth bet was significantly in the red as recently as March but may have, thanks to the extended session rally, turned green by press time on April 7.

Why UnitedHealth stock could still collapse in 2026

Lastly, it is noteworthy that, despite the positivity, there remain some notable potential headwinds for UNH stock investors. 

Specifically, the ongoing Iran war continues to threaten the global economy, and both a continuation and the escalation of the war could lead to significant inflation and productivity reductions as shortages of critical inputs mount, possibly ultimately leading to a significant recession.

Even with the latest tailwinds, UnitedHealth stock would be unlikely to evade the fallout of a market-wide crash.

Elsewhere, while President Donald Trump’s administration has been relatively kind to corporate America, any government-linked programs could arguably be seen as at risk of financing cuts as the commander-in-chief is pushing for a $1.5 trillion military budget at the expense of other sectors and of curtailing the national debt.
