NEW YORK (MarketWatch) -- U.S. stocks are mixed, with energy shares under heavy pressure after the Organization of the Petroleum Exporting Countries sent oil prices skidding, while airlines and retailers rejoiced.

The S&P 500 (SPX) edged to a record intraday high but soon pulled back to trade down 3.87 points at 2,068.96. The Dow Jones Industrial Average (DJI) clung to a 0.1% gain at 17,851.97, leaving it on track for another record close. The Nasdaq Composite (RIXF) rose 0.2% to 4,796.61.

U.S. markets were closed Thursday for the Thanksgiving holiday. U.S. stock and bond trading close early on Friday.

"With Black Friday upon us, investors are in the mood for some early festive cheer. However, as November draws to a close investors will reflect on what has been a difficult month with falling oil prices and artificially inflated equities on the promise of more central bank intervention," said Mike McCudden, head of derivatives at Interactive Investor in London.

Crude oil for January (CLF5) shaved off more than $4 from Wednesday's settlement price to trade at $69.44 a barrel after hitting its lowest point in more than 4 1/2 years. U.S. crude oil didn't settle on Thursday due to Thanksgiving, but OPEC's decision to maintain its current production ceiling of 30 million barrels a day does little to remove the glut that is keeping oil prices low.

Among major stock movers, Exxon Mobil Corp. (XOM) lost 3.4%, while fellow Dow component Chevron Corp. (CVX) dropped more than 5%.

Among other energy shares, Transocean Ltd. (RIG) sank 8.3%, ConocoPhillips (COP) fell 5.8% and Halliburton Co. (HAL) erased more than 10% of its value.

In Europe, the picture was the same, with oil heavyweights such as BP PLC (BP) and Total SA (TOT) posting big losses..

On the flip side, transportation companies were getting a lift from the prospect of lower energy prices. Delta Air Lines Inc. (DAL) surged 5.1%, Southwest Airlines Co. (LUV) rose 6.5% and Carnival Corp. (CCL) added 4.5%.

No major earnings reports or data releases were expected on Friday, and U.S. markets, in addition to the early closes, are expected to see a light post-Thanksgiving session.

Leading up to the holiday, the S&P 500 (SPX) and Dow Jones Industrial Average (DJI) scored their 47th and 30th record closes this year, respectively, on Wednesday.

Black Friday frenzy: Retailers were in the spotlight during early Friday, as shops opened the doors for their annual Black Friday sales (with some having opened late Thursday). Wal-Mart Stores Inc. (WMT) advanced 3.3%, Amazon.com (AMZN) rose 2% Macy's Inc. (M) added 2.4%, and Best Buy Co. (BBY) advanced 1.9%.

Wal-Mart reported early Friday that Thanksgiving Day delivered its second-highest online sales day ever, topped only by Cyber Monday last year.

Other markets: European stocks were mired in the red, with energy companies pulling the major benchmarks lower. Asian markets closed mostly higher.

Metals prices (GCG5) showed weakness, hurt by a rise in the dollar (DXY).
