U.S. stock futures edged higher Tuesday as investors parsed the implications of new tariffs taking effect, with the Nasdaq leading tentative premarket gains. The technology-heavy index showed resilience despite renewed speculation about how artificial intelligence might reshape industries, which had triggered heavy selling across multiple sectors in recent sessions.

The tariff announcement created a split in global markets, with European equities falling as traders weighed the potential economic impact. The divergent performance highlighted the uneven effect of trade policy across regions, with U.S. markets showing more optimism about domestic growth prospects despite the new trade barriers.

Market participants are now focused on how companies will adapt their supply chains and pricing strategies in response to the tariffs. The Nasdaq's outperformance suggests investors see technology companies as better positioned to weather trade tensions, particularly those involved in AI development and cloud computing services.
