Stock futures rose on Monday after Trump’s new “reciprocal” tariffs exempted tech products like smartphones and chips, though officials warned the exemptions may not last.

Here are some of Monday's biggest stock movers:

Biggest stock gainers

• Apple (NASDAQ:AAPL) +5.5% – Tech stocks saw a surge after the Trump administration temporarily excluded smartphones, laptops, and key electronics components from its new 145% reciprocal tariffs on Chinese goods. The U.S. Customs and Border Protection issued the exemptions late Friday, providing relief to tech stocks, though both President Trump and Commerce Secretary Howard Lutnick warned that these exemptions may not be permanent. Other notable gainers included Nvidia (NASDAQ:NVDA) +3%, Dell Technologies (NYSE:DELL) +7%, Super Micro Computer (NASDAQ:SMCI) +5.7%, Hewlett Packard Enterprise (NYSE:HPE) +5%, and HP (NYSE:HPQ) +6%.
• BP (NYSE:BP) +4% - Shares rose after the company announced the discovery of oil at the U.S. Far South prospect in the Gulf of Mexico. The discovery, which was made approximately 120 miles off the Louisiana coast at a depth of 23,830 feet, is part of BP’s strategy to increase its upstream production. Initial data suggests the presence of high-quality reservoirs and potentially commercial volumes of hydrocarbons. BP's revised strategy aims to increase its global upstream production to between 2.3M and 2.5M barrels of oil equivalent per day by 2030, with plans for further growth through 2035. The company also intends to drill around 40 wells over the next three years, with 10 to 15 wells expected to be drilled in 2025, underscoring its renewed focus on exploration.
• Warner Bros. Discovery (WBD) +2.5% – Shares rose after the company announced it would not sell Polish broadcaster TVN, putting an end to speculation surrounding the bidding process. In a statement on Monday, WBD explained that, following a strategic review of options for TVN, it had concluded that retaining ownership was the best path forward. The company emphasized its commitment to supporting its business and strategy, along with the journalistic efforts of its team. The decision comes amid financial market volatility triggered by U.S. President Donald Trump’s tariff policies, which have caused many investors to pause deal-making activities.
• DuPont de Nemours (DD) +3% – Shares climbed after KeyBanc upgraded the stock to Overweight from Sector Weight, citing the company’s strong balance sheet as a key factor in its ability to navigate a potential economic downturn. Analyst Aleksey Yefremov highlighted DuPont’s electronics and water segments as "world-class secular growth franchises" that are currently trading at unusually discounted valuations.
• Palantir (PLTR) +6% – Shares rose after NATO’s Communications and Information Agency finalized the acquisition to deploy Palantir’s Maven Smart System across Allied Command Operations. The AI-driven system aims to enhance battlefield decision-making and will be operational within 30 days. NATO emphasized the rapid six-month timeline from concept to implementation. NCIA General Manager Ludwig Decamps called it a “state-of-the-art AI capability” that equips forces to operate effectively in modern conflict zones.
• Viking Therapeutics (VKTX) +9% – U.S. obesity drugmakers rallied after Pfizer said it would halt development of its obesity pill, danuglipron, over a potential drug-related liver injury. While the side effect resolved after stopping treatment, the company decided to exit the program following a data review and regulatory feedback. Structure Therapeutics (GPCR) +7%, Terns Pharmaceuticals (TERN) +5%, Altimmune (ALT) +3%, and Novo Nordisk (NVO) +2%.

Biggest stock losers

• DaVita (DVA) -5% – Shares fell after the dialysis provider disclosed a ransomware attack affecting some operations. The company said it has isolated impacted systems, engaged third-party cybersecurity experts, and notified law enforcement, but it cannot yet estimate the scope or duration of the disruption.
