The stock has collapsed because nobody seems to know just how bad utilization rates have become. When UnitedHealth Group reported first-quarter results on April 17, management adjusted its 2025 earnings outlook from a range between $28.15 and $28.65 per share down to a range between $24.65 and $25.25 per share.

UNH has lost more than $200 billion in market value in the last six months. The company’s old CEO sees a fix. Investors should be wary.

Shares of UnitedHealth Group (NYSE: UNH) are falling on Thursday. The collapse comes as the S&P 500 gained 0.1% and the Nasdaq Composite fell 0.4%. The troubled health insurance giant is facing reports of a Department of Justice (DOJ) investigation into possible Medicare fraud.
