NEW YORK: The S&P 500 and Nasdaq indexes hit record closing highs on Wednesday, powered mainly by technology stocks as markets digested economic data that could support a much-expected start to the Federal Reserve's policy easing cycle.
Technology stocks led advances among the 11 S&P 500 sectors, followed by equities in communications and industrials sectors. Consumer staples stocks were the biggest losers.
The May private payrolls report on Wednesday was the latest data to suggest an easing in labor market tightness that could propel the Fed to begin cutting rates this year. A report on Tuesday showed job openings fell in April to the fewest in more than three years.
"We're seeing the economic data starting to ease up a little bit and the repercussions for that is that you're seeing the pressure on rates come off the boil a little bit mixed in with the potential for weaker economic data, which is a pretty good recipe for the bond market," said Jack Janasiewicz, a portfolio manager at Natixis Investment Managers Solutions in Boston.
Traders now see a nearly 69 per cent chance of a September rate reduction, according to the CME's FedWatch tool. Expectations had hovered around 50 per cent last week.
