# Health Care Down as Rotation From AI Cos Slows - Health Care Roundup

Health-care companies fell as a rotation out of artificial-intelligence bets into defensive health insurers slowed.

Novartis's U.S. shares fell after the Swiss drugmaker reported results of two late-stage studies of its multiple sclerosis pill that showed a reduction in flare-ups below that achieved by a rival drug from Roche Holding. 

UnitedHealth Group slipped but still finished the week with gains of more than 4%.
