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

- SanDisk (SNDK) shares rallied this week and was the best performer in the S&P 500 on Tuesday, soaring more than 22%. It came on the heels of Nvidia's roll out of new products at CES and CEO Jensen Huang mentioning storage as an "unserved market" in tech.

- Intel (INTC) shares gained the most since September after President Donald Trump touted the technological progress — and stock-market performance — of the long-struggling chipmaker. Trump met with Intel Chief Executive Officer Lip-Bu Tan on Thursday at the White House, where the two men discussed the company’s new line of processors following the US government’s purchase of shares in the chipmaker. Intel shares jumped 11% to $45.55 in New York on Friday following the remarks, the biggest single-day increase since Sept. 18. After an 84% gain in 2025, the stock is now up about 23% so far this year.

- Builders FirstSource (BLDR) soared this week along with shares in other homebuilder and mortgage-linked companies in response to President Donald Trump saying he’s directing Fannie Mae and Freddie Mac to purchase $200 billion in mortgage bond. In a move he cast as an effort to bring down housing costs. Fannie and Freddie common shares inched higher as analysts voiced mixed opinions about the impact of Trump’s move on long-simmering efforts to release the mortgage-finance giants from the government’s grip.
