May 10 (Reuters) - Wall Street was higher on Thursday after U.S. consumer prices increased modestly in April, cooling worries of accelerating inflation that would have made a case for faster interest rate hikes.
A Labor Department report showed its consumer price index (CPI) 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.
Excluding the volatile food and energy components, consumer prices rose 2.1 percent year-on-year in April, matching March's increase.
U.S. Treasury yields added to their earlier decline after the data.

"The market wants to see a breakout in a particular sector," said Robert Pavlik, chief investment strategist and senior portfolio manager at SlateStone Wealth LLC in New York. "So far, we've had in energy."
"If the kind of gains we saw yesterday holds over, people will move into the market. The next level of resistance to watch is probably around where we closed 2,700."
