Wall Street fell overnight after a report showed a slide in the pace of US manufacturing growth, while China's manufacturing also provided cause for concern.
The preliminary reading of Markit's gauge for US manufacturing slid to 55.5 in March, down from a 45-month high of 57.1 in the prior month.
"The manufacturing PMI adds to evidence that the sector has shrugged off the weather-related weakness seen earlier the year, with strong demand encouraging firms to expand and hire new staff at a robust pace," Chris Williamson, chief economist at Markit, said in a statement.
"The buoyant growth in March rounds off the best quarter for three years, indicating that the sector should provide a robust contribution to GDP in the first quarter," Williamson said. "One area of concern is the sluggish growth of exports, but this weakness is being more than offset by strong domestic demand."
Still today the data proved insufficient for investors. In afternoon trading in New York, the Dow Jones Industrial Average fell 0.26 per cent, the Standard & Poor's 500 Index shed 0.59 per cent, while the Nasdaq Composite Index dropped 1.43 per cent. Nasdaq was dragged lower by selling of both tech and biotech listed shares.
