June 3 (Reuters) - U.S. stock indexes edged higher on Tuesday, helped by gains in Nvidia and other chipmakers, as investors awaited possible negotiations between the United States and its trading partners for more clarity on Washington's tariff plans.
President Donald Trump and Chinese leader Xi Jinping are set to speak this week, the White House said on Monday, days after Trump accused China of violating an agreement to roll back tariffs and trade restrictions.
The Trump administration wants countries to provide their best offer on trade negotiations by Wednesday as officials seek to accelerate talks with multiple partners ahead of a self-imposed deadline in just five weeks, according to a draft letter to negotiating partners seen by Reuters.
Trump said last week he planned to double tariffs on imported steel and aluminum to 50% starting on Wednesday, fueling fresh concerns among investors and hampering global stocks as they approached record highs.
A softening of Trump's harsh trade stance allowed a recovery in risky assets in May, with the benchmark S&P 500 (.SPX), and the tech-heavy Nasdaq (.IXIC), posting their biggest monthly percentage gain since November 2023.
The S&P 500 remains less than 4% away from its record peak touched in February.
"The markets are still trading with a decent level of uncertainty because they're not sure how everything's going to turn out," said Chris Zaccarelli, chief investment officer at Northlight Asset Management.
"Having a best and final offer deadline and a framework to move forward should be positive for the markets."
At 10:40 a.m. the Dow Jones Industrial Average (.DJI), rose 10.40 points, or 0.02%, to 42,315.12, the S&P 500 (.SPX), gained 10.39 points, or 0.17%, to 5,946.18 and the Nasdaq Composite (.IXIC), gained 87.28 points, or 0.46%, to 19,330.74.
Six of the 11 major S&P 500 sub-sectors fell. Communication services (.SPLRCL), declined the most with a nearly 0.7% fall.
On the flip side, information technology stocks (.SPLRCT), led gains with a 0.8% rise, helped by a 2.7% rise in Nvidia (NVDA.O), opens new tab. Chipmaker Broadcom (AVGO.O), rose 2.1% ahead of its results later this week.
