On this episode of Stock Movers, we take a look at some of the week's biggest gainers and decliners:

-SanDisk (SNDK) ended the week higher. The digital storage company is extending its blistering rally as the top performing stock in the S&P 500 Index. The gains come as investors shift their bets from the biggest technology companies that are pledging billions of dollars in capital expenditures to build out artificial intelligence technology to the beneficiaries of that spending. The group includes memory storage makers as well as other stocks associated with AI infrastructure. 

-Humana (HUM) shares dropped at the end of the week following a proposal from the Trump administration to limit federal payments to the plans, known as Medicare Advantage, next year. Some of the pullback in government support has been percolating for a long time, but there’s no sign things will turn around soon. As Trump increasingly faces criticism for Americans’ affordability challenges, he has begun targeting insurers. In December, he said insurance companies “are making so much money, and they have to make less, a lot less.”

-Deckers (DECK) ended the week higher after the owner of the Ugg and Hoka footwear brands raised its annual earnings and sales forecast, beating the average analyst estimate. Analysts note strength in the retailer’s direct-to-consumer (DTC) channels in the United States.
