Stocks drop, weighed down by falling oil prices

The latest downturn in crude oil prices put investors in a selling mood Wednesday, pulling U.S. stocks lower for the second time this week.

The market decline, which wiped out some of the gains from a rally the day before, came on lighter-than-usual trading ahead of the New Year’s Day holiday.

Energy companies fell the most among the 10 sectors in the Standard & Poor’s 500 index, 1.5%. The sector is down 23.8% for the year. Southwestern Energy fell 6.8%, while Consol Energy sank 5.6%.

The price of oil shed 3.4% on Wednesday, extending its losses for the year to nearly 40%.

“You have oil prices affecting the market negatively today,� said Quincy Krosby, market strategist for Prudential Financial. “You throw in exceedingly low volume and it’s a recipe for skewing the market, in this case to the downside.�

The Dow Jones industrial average fell 117.11 points, or 0.7%, to 17,603.87. The S&P 500 index dropped 15 points, or 0.7%, to 2,063.36. The Nasdaq composite lost 42.09 points, or 0.8%, to 5,065.85.

The day’s market action cut into the S&P 500’s slim gain for the year. The index remains essentially flat with an increase of 0.2% this year. The Nasdaq is up about 7%, while the Dow is on track to end 2015 with a loss of 1.2%.

The major stock indexes headed lower from the get-go on Wednesday as investors tracked the latest swings in oil and natural gas prices.

Several energy companies closed lower, including Noble Energy, which fell $1.18, or 3.5%, to $32.22, and Southwestern Energy, which tumbled 46 cents, or 6.8%, to $6.30.

Traders found good reasons to bid up other stocks.
