U.S. stock futures edged lower Tuesday as investors digested a mixed batch of quarterly earnings and awaited the latest inflation data. The market reaction was sharp but scattered across sectors.JPMorgan Chase managed a slight premarket gain despite reporting a fourth-quarter profit drop, which stemmed from a one-time charge related to losing its credit card partnership with Apple.

The move signals strong federal backing for domestic manufacturing capabilities. Meanwhile, semiconductor stocks rallied following an analyst upgrade. KeyBanc boosted both Intel and Advanced Micro Devices to 'overweight', citing better-than-expected data center demand and tightening memory supply—a classic sign of a recovering chip cycle.

Not all news was positive. Delta Air Lines dropped sharply after its revenue missed estimates and its 2026 guidance disappointed investors looking for a travel boom延续. Travere Therapeutics also slumped following an FDA request for more clinical data on its kidney disease treatment.
