Wall Street seesawed after reaching fresh record highs earlier in the day amid bets on an upbeat outlook for economic and corporate profit growth, while oil prices slid on a stalemate between Iran and Iraq on production cuts.
In 1.15pm trading in New York, the Dow Jones Industrial Average rose 0.16 percent, while the Nasdaq Composite Index added 0.23 percent. In 1pm trading, the Standard & Poor's 500 Index inched 0.01 percent lower.
Wall Street earlier touched fresh record highs, with the Dow reaching 19,014.73, while the S&P 500 climbed to 2,203.56 and the Nasdaq hit a record 5,392.26.
"If we see the indexes close above the 19,000 and 2,200 levels, that would say we are going to move higher," Brad McMillan, chief investment officer at Commonwealth Financial, told Reuters. "I don't think we're going to see that in the next day or two. I think there might be selling around that level."
In the Dow, gains in shares of Verizon Communications and those of Home Depot, up 2.3 percent and 1.8 percent respectively, outweighed slides in shares of Visa and those of Johnson & Johnson, down 2.7 percent and 1.9 percent respectively.
