Healthcare Shares Lose Ground

Dow Jones04:52

Stocks in the healthcare sector fell as investors took on more risk and shifted some funds out of defensive holdings.

The Food and Drug Administration walked back an earlier statement that a sample of lettuce from Taylor Farms tested positive for cyclospora, but noted that tests are continuing on products pulled from the market. The finding complicates the messaging from health authorities tracking the source of a major foodborne-illness outbreak and efforts to address concerns from the public about which foods are safe to eat.

Tempus AI has agreed to buy the rest of genomics company Personalis in a deal that expands the technology company's capabilities in minimal residual disease. Tempus, which already owns more than 12% of Personalis, said it will pay $16.25 a share in stock for the rest of the Fremont, Calif., company, a 5.6% premium to Friday's closing price of $15.39. Chicago-based Tempus said the deal represents a total enterprise value of $1.5 billion, net of its existing Personalis stake.

Bristol Myers Squibb said it will expand its partnership with Nvidia, advancing its artificial-intelligence infrastructure to increase both computational power and efficiency. The biopharmaceutical company on Monday said it will deploy Nvidia DGX Vera Rubin NVL72 systems across its stack.
