The S&P 500 hit a new high today but the Dow dropped over 400 points. The main drag was UnitedHealth which fell nearly 20%. The government proposed raising Medicare Advantage rates by only 0.09% which was well below expectations. This pulled down other insurers like Humana and CVS as well. Tech stocks offset the drop. Micron rose 5.5% after announcing a new factory in Singapore. Corning also jumped 17% on a deal to supply fiber optics to Meta. Microsoft and Apple finished green ahead of earnings later this week. The Fed interest rate decision is coming up Wednesday. Most analysts expect a pause. Also saw Michael Burry mentioned he is buying GameStop again.
