Wall Street gains on tech boost, easing trade tensions

US stocks have closed higher, rallying for a third straight day with a solid boost from technology shares as investors parsed a mixed bag of corporate earnings and watched for signs of progress in the US-China tariff stand-off.

All three major US stock indexes posted sharp gains, with the "magnificent seven" group of artificial intelligence-related megacaps, boosted by AI-powered software firm ServiceNow's better-than-expected quarterly results, giving the Nasdaq the edge.

China called for cancellation of US tariffs on Chinese goods following comments from US Treasury Secretary Scott Bessent signalling the White House could be willing to de-escalate trade tensions that have whipsawed markets for weeks.

Easing tariff rhetoric is "part of the reason why you're seeing the chips lead because they've been kind of in the bull's eye in (the trade dispute) between China and the US," said Paul Nolte, senior wealth adviser & market strategist at Murphy & Sylvest in Elmhurst, Illinois.

"So any cooling of tariff talks between the two countries bolsters the technology sector as a whole."

"There's still a ton of questions around tariffs right now that we really don't have answers to," Nolte added.

"So a lot of us are just kind of throwing darts in the dark."

On the data front, stronger-than-expected new orders for durable goods and rangebound jobless claims painted a picture of economic resilience.
