Stocks and commodities including copper and iron ore fell after a surprise drop in China's exports bolstered concern about the slowing growth in the world's second-largest economy.
China's exports sank 18.1 per cent in February from a year earlier, according to General Administration of Customs data on the weekend. As a result, copper futures for May delivery shed 1.5 per cent to US$3.0355 a pound in afternoon trading on the Comex in New York, extending Friday's slide of about 4 per cent.
In afternoon trading in New York, the Dow Jones Industrial Average fell 0.35 per cent, the Standard & Poor's 500 Index slipped 0.14 per cent, while the Nasdaq Composite Index edged 0.13 per cent lower.
"Any poor news from China is always going to hit short-term market sentiment, especially in the mining sector, and fears of slower growth will hit base metals," IPR Capital director Steven Mayne told Reuters.
Slides in shares of Boeing, last down 2.3 per cent, and those of Verizon, last down 0.9 per cent, led declines in the Dow.
