10 Stocks That Stole the Show Today

4. UnitedHealth Group Incorporated (NYSE:UNH)

Shares of UnitedHealth Group rallied by 8.21 percent on Monday to close at $315.89 apiece as investors resumed bargain-hunting after the company hit a new 52-week low late last week, weighed down by reports that it is being investigated over alleged fraudulent activities in its Medicare payouts.

On Thursday, the Wall Street Journal reported that the Department of Justice (DOJ) is investigating UnitedHealth Group Incorporated (NYSE:UNH) over its Medicare billing practices, sending its share prices falling to its lowest level of $248.88.

According to the report, the investigation has been ongoing since the middle of 2024 to look into whether the company fraudulently inflated patient diagnoses to rake in higher payouts from Medicare.

Meanwhile, UnitedHealth Group Incorporated (NYSE:UNH) called the report “deeply irresponsible, as even it admits that the ‘exact nature of the potential criminal allegations is unclear.’”

It said that it had not been formally notified of any criminal investigation but said that it “stands by the integrity of [its] Medicare Advantage program.”

Shareholder law firms have launched their own investigations into potential securities fraud alleged in the pending suit.
