Today's biggest winners and losers in the stock market.

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

- SpaceX (SPCX) stock ended higher in its first week of trading, even though its rough ride showed the largest-ever IPO was not immune to the type of share-price volatility that tends to rock big companies after they go public. Shares of Elon Musk’s rocket, satellite and artificial intelligence company fell 3.6% Thursday, bringing a two-day decline to 8.3%. Still, the company ended its first week of trading as a public company 37% above the $135 price of its record initial public offering. The company’s total market capitalization at close was $2.4 trillion, making it the sixth-largest company in the world.

- Intel (INTC)'s stock surged on Thursday after US President Donald Trump said the chipmaker will work with Apple to design and produce semiconductors domestically. Trump didn’t elaborate on the tie-up, which he mentioned after championing Nvidia Corp. and Elon Musk’s Terafab chipmaking ambitions in a Truth Social post. The iPhone maker has held exploratory discussions about using Intel and Samsung Electronics Co. to produce the main processors for its devices in the US, Bloomberg previously reported.

- Apple (AAPL) shares ended the shortened trading week higher after CEO Tim Cook told the Wall Street Journal that the iPhone maker plans to raise prices on its products to offset the increasing costs of memory and storage chips. Some analysts believe demand for the products are inelastic enough to lift sales.
