DIsney, AMD, Novo Nordisk rise premarket; Uber and Marvell fall

Investing.com -- U.S. stock futures rose Wednesday, boosted by scheduled trade talks between the U.S. and China ahead of the conclusion of the latest Federal Reserve policy meeting.

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

• Walt Disney (NYSE:DIS) stock rose 6.2% after the entertainment giant reported fiscal second-quarter earnings that beat on the top and bottom lines, boosted by better-than-expected subscriber growth for its Disney+ streaming platform as well as increased spending in its U.S. theme parks.

• Uber (NYSE:UBER) stock fell 3.5% after the ride-hailing service reported weaker-than-expected quarterly gross bookings and slower gains in its rideshare business, amid concerns about a slowing economy.

• Advanced Micro Devices (NASDAQ:AMD) stock rose 1.5% after the chipmaker unveiled upbeat second-quarter revenue guidance, driven by many clients racing to lock in purchases prior to the implementation of U.S. tariffs.

• Marvell (NASDAQ:MRVL) stock dropped 7% after the semiconductor announced it would postpone its Investor Day, initially scheduled for June 10, to a date in 2026, citing the current uncertain macroeconomic environment.

• Super Micro Computer (NASDAQ:SMCI) stock fell 5.3% after the data center solutions provider reported third-quarter earnings that narrowly beat estimates but fell short on revenue and lowered its full-year outlook.

• Novo Nordisk (CSE:NOVOb) (NYSE:NVO) stock rose 5.5% after the drugmaker cut its sales forecasts on Wednesday for the first time since the launch of its Wegovy weight-loss drug four years ago, but it still anticipated a recovery in its biggest U.S. market.

• Boeing (NYSE:BA) stock rose 0.3%, underperforming the wider market after the Financial Times reported that the European Union intends to propose tariffs on the aircraft manufacturer, as it prepares to retaliate further if trade talks with Washington fail.

• Tripadvisor (NASDAQ:TRIP) stock rose 3.4% after the online travel company reported first-quarter top and bottom lines that beat analyst expectations.

• Sarepta (NASDAQ:SRPT) stock fell 20% after the gene therapy developer reported strong revenue growth in the first quarter, but this was overshadowed by operational challenges and a significant guidance reduction.

• BorgWarner (NYSE:BWA) stock rose 3% after the automotive and e-mobility supplier lifted its annual sales outlook and reported first-quarter results that exceeded average market estimates.
