UnitedHealth Shares Spark Their Biggest Rally in 5 Years After Buffett Move
**Date: August 15, 2025**
**Minnetonka, Minn.** — In an electrifying turn of events, UnitedHealth Group’s (UNH) stock achieved its most dramatic one-day surge in half a decade, soaring more than 12% following the revelation of a major new stake from Warren Buffett’s Berkshire Hathaway.
According to a filing with the U.S. Securities and Exchange Commission, Berkshire acquired over 5 million shares, valued at approximately \$1.57 billion as of the end of the second quarter ([AP News][1], [Reuters][2], [Business Insider][3]). Premarket trading saw a roughly 12% climb, and by official hours, the surge hit the 11–13% range depending on the outlet ([The Economic Times][4], [Financial Times][5], [Business Insider][3]).
### Not Just a Gain—A Comeback
This is UnitedHealth’s strongest single-day rebound in five years, propelling the stock above the psychologically pivotal **\$300 mark**—a level it hadn’t surpassed since mid-July ([The Economic Times][4]). Analysts now peg a potential upside of over **20–24%** from current levels, prompting some to dub UNH a "must-buy" in the midst of healthcare sector volatility ([The Economic Times][6]).
### The Buffett Effect: More Than Symbolism
Market watchers aren't just calling it a bullish spike—they see a deep strategic endorsement. The Buffett-backed move provides a vote of confidence amid UnitedHealth’s recent turbulence: ongoing federal probes into Medicare Advantage practices, cyber challenges, leadership upheaval, and tepid earnings performance ([AP News][1], [Financial Times][5], [Reuters][2]). Analysts say this “Buffett Bounce” underscores long-term faith in the company’s resilience and diversified offerings ([Investopedia][7], [The Economic Times][6]).
