The Standard & Poor's 500 Index crept to a fresh intraday record high as investors await the second estimate of US economic performance in the first quarter, scheduled to be released tomorrow.
A preliminary estimate showed the US economy had expanded at a 0.1 per cent annualised rate in the first three months of 2014, but economists predict the second estimate might show it shrank.
Recent economic data have indicated the world's largest economy is performing better than anticipated, while the US Federal Reserve has indicated it is in no rush to raise interest rates. Those factors have helped underpin both Wall Street and US Treasuries.
In the final hour of trading in New York, the S&P 500 was up 0.08 per cent at 1,913.36, after touching a record high 1,914.46 earlier in the session.

A report showed that unemployment in Germany, the euro zone's biggest economy, unexpectedly rose in May, bolstering expectations the European Central Bank will ease monetary policy at its June meeting. The euro weakened as a result, declining 0.3 per cent against the greenback.
Euro-zone bonds, however, advanced as a decrease in interest rates makes fixed-income securities pegged at higher rate more appealing. Yields on Germany's benchmark 10-year bond declined five basis points to 1.34 per cent.
"What we're seeing is continued focus on the increasing likelihood of policy easing next week from the central bank," Omer Esiner, chief market analyst in Washington at Commonwealth Foreign Exchange, a currency brokerage, told Bloomberg News.
