The Standard & Poor's 500 Index rose to a fresh record after solid data on US jobs and factory orders underpinned optimism about the outlook for the world's largest economy.
US companies added 191,000 payrolls in March, according to ADP Research Institute data, while a separate Commerce Department report showed factory orders rose 1.6 per cent in February, up from a revised 0.5 per cent increase in January.
The company-hiring data "showed a respectable and near-expected gain, but that probably won't boost expectations for Friday's full nonfarm payrolls number," Robert Lynch, a currency strategist at HSBC Holdings in New York, told Bloomberg News.
Friday's report is expected to show nonfarm payrolls rose by 200,000 in March, the largest gain in four months, according to a Reuters poll of economists.
In afternoon trading in New York, the S&P 500 was last up 0.11 per cent. Earlier it rose to a record 1,890.80. The US dollar also gained, up 0.2 per cent against the yen as well as the euro.
