Wall Street was mixed overnight as a decline in oil prices weighed on energy shares, offsetting optimism about a strong US economy and a supportive central bank.
In afternoon trading on Wall Street, the Dow Jones Industrial Average slipped 0.03 per cent, while the Standard & Poor's 500 Index edged 0.04 per cent lower. The Nasdaq Composite Index gained 0.37 per cent, helped by Apple.
"The action is very constructive in general. It's one of the strongest months in years for the S&P 500, the Nasdaq just a hair away from all-time highs, and we came up very far, very fast," Adam Sarhan, chief executive of Sarhan Capital in New York, told Reuters. "But we've had a big move ... and you have to expect some profit-taking to come in,"
Slides in shares of IBM and those of Chevron, last down 1.8 per cent and 1.3 per cent respectively, offset gains in shares of Johnson & Johnson and those of Cisco, up 1.7 per cent and 1.5 per cent respectively.
Shares of Chevron fell, as did those of Exxon Mobil, last down 1 per cent, with other energy companies, as oil prices moved lower amid concern about rising US inventories.
