Wall Street declined, sending the Standard & Poor's 500 Index down from its record high close on Thursday, after the latest headline manufacturing data fell short of expectations.
The Institute for Supply Management's index of national factory activity dropped to 51.3 in March, from 54.2 in February. The median forecast of 69 economists surveyed by Bloomberg projected the ISM's factory index would drop to 54.
Even so, Markit's US Manufacturing Purchasing Managers' Index posted 54.6 in March, up from February's 54.3 but down from the earlier flash estimate of 54.9.
"Manufacturers enjoyed another month of strong output and order book growth in March, finishing off the best quarter for two years," Chris Williamson, chief economist at Markit, said in a statement. "The sector will have provided a firm boost to the economy in the first quarter."
In afternoon New York trading, the Dow Jones Industrial Average fell 0.14 per cent, the Standard & Poor's 500 Index shed 0.53 per cent, while the Nasdaq Composite Index dropped 0.77 per cent.
