Warren Buffett just surprised Wall Street by scooping up a chunk of UnitedHealth stock, even as the company’s been in the hot seat over healthcare costs and a DOJ probe. The twist? Shares jumped 8.5% after hours. If you’re tracking your 401(k), this is a reminder that when Buffett makes a move, markets listen. It’s like when your foodie friend raves about a new restaurant—suddenly, everyone wants in. #Business #EntrepreneurshipStartup #UnitedHealth
