Wall Street advanced in late afternoon trading as better-than-expected services sector data outweighed concern about the escalating crisis in Ukraine.
With about an hour of trading left in the day in New York, the Dow Jones Industrial Average rose 0.16 per cent, while the Standard & Poor's 500 Index gained 0.09 per cent, and the Nasdaq Composite Index added 0.15 per cent.
Gains in shares of Boeing and Visa, up 1.7 per cent and 1.3 per cent respectively, led the Dow higher. JPMorgan slumped 2.7 per cent after warning late on Friday that it expects bond and equity trading revenue to drop in the second quarter.
There was good news on the economic front, already lifted by a recent string of data showing that the world's largest economy is emerging stronger than anticipated from a harsh winter. The Institute for Supply Management said its services sector index climbed more than expected to 55.2 in April, up from 53.1 in March.
"It's more confirmation the economy is strengthening and we are headed for stronger growth," Peter Cardillo, chief market economist at Rockwell Global Capital in New York, told Reuters.
