U.S. stock futures climbed on Wednesday as global markets reacted positively to a breakthrough U.S.-South Korea trade agreement and upbeat earnings reports from Big Tech companies. The new trade deal, finalized on July 30, significantly reduced tensions, with South Korea agreeing to invest $350 billion in U.S.-controlled projects and purchase $100 billion in American energy products. The agreement also lowered tariffs on South Korean imports from a planned 25% to 15%, easing immediate fears of a trade war and opening new growth channels for industries tied to both countries.

Investors cheered the breakthrough, which is expected to unlock opportunities across automotive, semiconductor, steel, and energy sectors. U.S. markets saw futures for the Dow Jones, S&P 500, and Nasdaq rise in premarket trading, reflecting optimism for improved corporate profits and a more stable international trade environment.

At the same time, major U.S. technology firms reported strong quarterly results, further boosting sentiment. With robust demand for AI-related products, cloud computing, and digital advertising, tech stocks helped lead the rally in equity indexes. This dual tailwind—supportive policy from the U.S.-South Korea agreement and exceptional Big Tech performance—has set a constructive tone for global markets as the new trading quarter begins.

For investors, focus is now shifting to those companies best poised to benefit from the increased cross-border investment and global supply chain stability. Analysts highlight opportunities among leading auto manufacturers, chipmakers, and energy exporters as direct beneficiaries of the deal. The combination of fresh capital, lowered trade barriers, and strong earnings momentum could provide broader support for markets in the weeks ahead, even amid wider macroeconomic uncertainties.
