UnitedHealth Group Inc. (UNH) experienced its most dramatic weekly rally since 2009 following a game-changing investment by Warren Buffett’s Berkshire Hathaway. On August 15, 2025, investor optimism soared as Berkshire disclosed a $1.57 billion, 5 million‑share stake in UnitedHealth—a bold vote of confidence in a company wrestling with regulatory and operational turbulence.
The revelation propelled UNH shares up 11–12% in premarket trading, marking the insurer’s largest single-day gain in over a decade. By week’s end, the surge vaulted UnitedHealth to the top gainer among S&P 500 components, capping its strongest week since 2009.
UnitedHealth’s meteoric rise had broader market implications. Its performance contributed significantly to a momentary record high for the Dow Jones Industrial Average, boosting the index by over 167 points earlier that day, even though it closed just shy of setting a new record.
Market watchers interpreted Buffett’s investment as classic value investing—snapping up a high-quality company that's showing weakness but has underlying strengths.The stock’s valuation, now trading at roughly 15–16 times forward earnings, appears enticing relative to its historical norms.
Rising healthcare and reimbursement costs continue to pressure margins.Broader sector challenges, including scrutiny of pharmacy-benefit managers like Optum Rx—a key part of UnitedHealth’s business—persist. The company is still recovering from internal turmoil, including the tragedy of a company executive’s death in 2024 and leadership changes.
Analysts caution that regulatory reforms in Medicare Advantage rating and coding systems could further delay a turnaround in profitability.
UnitedHealth is projecting a return to earnings growth by 2026, though details remain murky
Following Berkshire’s entry, other major investors—including Appaloosa Management, Lone Pine Capital, and Two Sigma—also added to their positions, reinforcing bullish sentiment despite the risks.
