Wall St edges up ahead of Powell speech

Wall Street's main indexes inched higher on Tuesday as investors assessed stronger-than-expected producer prices data and awaited a speech by Federal Reserve Chair Jerome Powell for clues on the interest-rate trajectory in the world's biggest economy.

U.S. producer prices increased more than expected in April amid strong gains in the costs of services and goods, leading traders to pare back bets of a first rate cut in September.

"Sticky inflation looked downright stuck this morning after a much hotter-than-expected inflation reading. But with last month's numbers revised lower, this report may not have been as much of an upside shock as it first appeared to be," said Chris Larkin, managing director of trading and investing at E*TRADE from Morgan Stanley.

Focus will now be on Wednesday's consumer price figures to help assess whether the upside surprises in the first quarter were a blip or a worrying trend.

Fed Chair Powell is due to speak at 10:00 a.m. ET.

Sticky inflation and persistent labor market strength have prompted financial markets and most economists to push back expectations for an initial Fed interest rate cut to September, from March seen at the start of the year.

Still, stocks have rallied so far this year, with all three major U.S. indexes hovering near fresh record highs thanks to better-than-expected earnings for the first quarter and hopes that the Fed will cut rates sometime this year.
