Financial markets in the U.S. edged higher at midday Friday in quiet trading a day after Christmas. Falling oil and natural gas prices helped bolster expectations for stronger consumer spending heading into next year. Utilities stocks were among the biggest gainers.

KEEPING SCORE: The Dow Jones industrial average rose 43 points, or 0.2 percent, to 18,073 as of 12:07 p.m. Eastern time. The Standard & Poor's 500 gained eight points, or 0.4 percent, to 2,089. The Nasdaq composite added 25 points, or 0.5 percent, to 4,799.

ENERGY: Benchmark U.S. crude oil fell 57 cents to $55.27 a barrel. Oil prices have been a major focus in markets over the past few weeks as they have fallen by about a half since the summer. Natural gas slipped 3 cents to $3 per 1,000 cubic feet.

THE QUOTE: Investors are cheering the slide in oil and natural gas prices, anticipating the trend should help boost consumer spending, which accounts for 70 percent of the U.S. economy, said Phil Blancato, CEO and president of Ladenburg Thalmann Asset Management.

Also giving the market a lift: Money managers typically put remaining cash back to work in their funds ahead of the end of the year.

"They realize they're in the strongest spending season of the year, so it's hard not to find good data," Blancato said. "There's lighter volume with people being out of the office, so there's a lot on your side that's going to drive the market."
