Stock market today: Nasdaq leads Dow, S&P 500 futures higher as chip stocks revive - Yahoo Finance

What the report says

Yahoo Finance reported that U.S. stocks advanced on Tuesday, July 21, 2026, as strength in semiconductor shares helped lift major indexes while investors monitored trade tensions, the U.S.-Iran conflict and corporate earnings. The Nasdaq Composite rose 1.3%, leading the move higher, while the S&P 500 added 0.9% and the Dow Jones Industrial Average gained more than 0.7%. The rebound followed a weaker session Monday tied to heightened geopolitical concerns.

Chipmakers were a central driver of the rally, according to the report, with the sector extending a recovery that had also been seen in Asian markets. Nvidia shares were up nearly 2% after the company disclosed an investment in Nebius, described by Yahoo Finance as a neocloud provider. The gains came ahead of a busy stretch of major technology earnings, including Alphabet’s results expected Wednesday, with Wall Street focused in part on companies’ artificial intelligence spending plans.

The market move came despite fresh uncertainty over U.S. trade policy. Yahoo Finance said President Trump announced 50% tariffs on a range of Canadian goods, including beer, hockey sticks, milk and chemicals, with implementation expected in 30 days. The report said Canadian oil imports were excluded, a notable carveout as crude prices remained elevated.

Investors were also weighing developments in the Middle East after another escalation in the U.S.-Iran war pushed Brent crude back above $91 per barrel before prices eased slightly Tuesday morning. Fresh earnings, including from General Motors and other companies, added to the broader mix of factors shaping market sentiment.
