Warren Buffett is helping revive shares of beleaguered UnitedHealthcare Group after taking a $1.6 billion stake in the company, according to filings with the Securities and Exchange Commission.
UnitedHealth shares clocked the largest one-day percent increase since March 2020, as tracked by Dow Jones Market Data Group. It was on pace for the best day in 17 years before giving back some of those gains. For the week, shares rose over 21%, the best week since May 2009. Still, the stock is down more than 50% over the past 12 months.
Investors, taking a cue from Buffett’s interest in healthcare, also piled into Vanguard Health Care Index Fund ETF Shares and The Health Care Select Sector SPDR Fund.

Buffett’s Berkshire Hathaway is known for taking positions in businesses it believes will perform over the long term and that have become, in some cases, undervalued.
The healthcare giant has been plagued by a Department of Justice probe and the fallout from the fatal shooting of executive Brian Thompson outside the Midtown Hilton Hotel in New York City last year. The brazen killing turned a critical spotlight onto the nation’s healthcare insurance system. Luigi Mangione has been charged with murdering Thompson.
