Investing.com -- U.S. stock futures slipped lower Friday ahead of the release of key inflation data, as investors seek guidance over future Federal Reserve monetary policy.

Here are some of the biggest premarket U.S. stock movers today:

  • Dell Technologies (NYSE:DELL) stock fell 5.7% after the tech giant’s dour quarterly profit forecast and weaker-than-expected second-quarter margin rate overshadowed upbeat full-year estimates.

  • Caterpillar (NYSE:CAT) stock fell 2.9% after the heavy-equipment maker forecast higher tariff-related expenses for 2025, as companies scramble to assess the impact of shifting U.S. trade policy.

  • Alibaba (NYSE:BABA) ADRs rose 3.4% after the Chinese online marketplace reported strong gains in its cloud computing business, even as it missed market estimates for quarterly revenue.

  • Marvell Technology (NASDAQ:MRVL) stock fell 14% after the tech company posted disappointing guidance for the current quarter. Bank of America also downgraded its stance to “neutral” from “buy”, citing reduced confidence in the company’s artificial intelligence growth trajectory through 2026.

  • Ulta Beauty (NASDAQ:ULTA) stock rose 3.2% after the beauty company raised its annual sales and profit forecast after topping quarterly sales estimates, banking on steady demand for makeup and skincare brands at its stores as well as lower inventory losses.

  • Affirm Holdings (NASDAQ:AFRM) stock soared 15% after the buy-now-pay-later company crushed revenue estimates and delivered an upbeat forecast, boosted by resilient consumer spending.

  • Autodesk (NASDAQ:ADSK) stock rose 10% after the software developer raised its annual revenue and profit forecasts, betting on growing demand for its design and engineering software.

  • Celsius Holdings (NASDAQ:CELH) stock soared 7.6% after soft drinks giant PepsiCo increased its stake in energy drink maker through a $585 million deal.

  • Ambarella (NASDAQ:AMBA) stock climbed 18% after the semiconductor design company raised its full-year revenue growth guidance, citing broad-based AI application momentum.
