US stocks fell on Thursday as a renewed sell-off in the tech sector rattled a market already weighed down by concerns about the impact of Donald Trump’s trade tariffs on the world’s biggest economy.
The blue-chip S&P 500 was down 1.9 per cent by early afternoon, with consumer cyclicals and financials among the sectors hit hardest.
The tech-heavy Nasdaq Composite lost 2.4 per cent, with chipmaker Marvell Technology plunging as much as 20 per cent after its first-quarter results disappointed.
Nvidia, which was down 4.8 per cent, led the tech rout, while other chipmakers such as Broadcom slumped 5.5 per cent ahead of its earnings report due after close.
Wall Street stocks have weakened over the past two weeks as Trump’s tariffs on China, Mexico and Canada sparked fears over the hit to growth.
They briefly pared losses on Thursday after the US granted the latest tariff reprieve to its trading partners before resuming their decline. The White House said all goods compliant with its 2020 trade deal with Canada and Mexico would be exempt from the levies for a month.
“Investors are starting to think the US administration is losing control of the narrative,” said Luca Paolini, chief strategist at Pictet Asset Management.

Thursday’s wobble is the latest in swing on Wall Street this week as investors weigh the fallout from Trump’s tariffs on the US’s three largest trading partners, a last-minute exemption for carmakers and the threat of more sweeping tariffs next month.
“We are in a ping-pong market,” said Mike Zigmont, co-head of trading at Visdom Investment Group. “At the moment, the market [takes] the latest White House soundbite as fact, but it is ready to go the other way in a heartbeat.”
Stocks have also been hit in recent weeks by worsening economic data, including manufacturers reporting a steep decline in orders in February.
Private sector jobs data on Wednesday showed that only 77,000 jobs were created in February, compared economists’ estimate of 140,000. Closely watched non-farm payrolls figures on Friday will offer the latest indication of the health of the US labour market.
European stocks, however, continued a recent rally that has led them to outperform Wall Street this year. The Europe Stoxx 600 closed up 0.1 per cent, while Germany’s Dax, which has surged following a historic €500bn spending package from Berlin announced earlier in the week, gained 1.6 per cent.
The euro extended its recent rise on Thursday, climbing 0.2 per cent to $1.081, its highest level against the dollar since November. The US currency was down 0.2 per cent against a basket of rivals.
