May 10 (Reuters) - The Dow Jones Industrial Average was on track for sixth day of gains and the S&P 500 edged past a key technical level after tepid inflation data cooled worries of faster interest rate hikes.
A Labor Department report showed its consumer price index rose 0.2 percent, below the economists' expectation of 0.3 percent, as rising costs for gasoline and rental accommodation were tempered by a moderation in healthcare prices.
"This data lends to the argument that the Fed can normalize patiently, but the flip side is that prolonged policy accommodation has yet failed to accelerate inflation," Peter Cecchini, chief market strategist at Cantor Fitzgerald in New York, wrote in a note.
U.S. Treasury yields fell after the data.
Investors have been worried about a build up in price pressures and the pace of interest rate hikes, especially after a recent reading on inflation crossed the Federal Reserve's 2-percent target.
Stocks have been riding an oil rally for the past two days following President Donald Trump's decision to withdraw the United States from a nuclear deal with Iran.
Oil prices were down slightly on Thursday, as investors took profits on a rally triggered by potential disruption to oil flows from major exporter Iran.
Rising oil prices have helped the S&P 500 energy index outperform other major sectors in the quarter, with gains of 12.6 percent.
"The market wants to see a breakout in a particular sector. So far we've had energy." said Robert Pavlik, chief investment strategist and senior portfolio manager at SlateStone Wealth LLC in New York.
"If the kind of gains we saw yesterday holds over, people will move into the market."
