NEW YORK, Dec 26 (Reuters) - U.S. stock prices were mixed while Japan pushed to a six-week high in thin post-Christmas bargain hunting on Friday as investors picked through the carnage amid the final days of a year many would like to forget.
Commodity prices rose. Crude oil prices gained on news that No. 5 oil exporter United Arab Emirates was cutting production to comply with last week's output cut by OPEC of 2.2 million barrels per day, the cartel's biggest ever.
The U.S. dollar climbed versus a basket of currencies. The price of gold rose while copper rebounded from a four-year low.
European stock and debt markets remained closed on Friday.
General Motors Corp <GM.N> shares jumped 13.2 percent to $3.68 on Wednesday's decision by the the U.S. Federal Reserve to recognize the carmaker's financing arm, GMAC, as a bank holding company. GMAC can now access government lending programs.
"It's significant in terms of GM's ability to move cars," said Erich Merkle, an auto analyst at consultant Crowe Horwath in Grand Rapids, Michigan.
"Things are still pretty ugly out there (in terms of sales) but in terms of GM possibly filing for bankruptcy, in my mind that's not going to happen. The reason I'm saying this is what they (the government) are doing with GMAC right now."
Last week the White House threw U.S. automakers a $17.4 billion lifeline of emergency loans in an attempt to stave off a collapse that could jeopardize hundreds of thousands of jobs.
In thin U.S. stock trading, the Dow Jones industrial average <
> was up 1.51 points, or 0.02 percent, at 8,469.99. The Standard & Poor's 500 Index <.SPX> was down 1.22 points, or 0.14 percent, at 866.93.

The Nasdaq lost despite news that Apple <AAPL.O> will begin selling some models of its popular iPhone at top global retailer Wal-Mart Stores Inc <WMT.N> on Sunday. Apple's stock rose 0.9 percent at $85.80.
The S&P 500 stock index is down nearly 41 percent in 2008, its second worst performance on record after a 47.1 percent drop in 1931.

Year-end portfolio window dressing overcame a record 8.1 percent plunge in November industrial production. Core inflation fell faster than forecast, putting the country on course for its second spell of deflation this decade.
The data on deflation plus month-end buying from pension funds drove government bonds higher and pushed the 20-year yield to a five-year low of 1.755 percent, down 6.5 basis points <JP20YTN=RR>.
"The Japanese economy is unlikely to bottom out until October-December next year as output is expected to remain very weak until then," said Naoki Iizuka, senior economist at Mizuho Securities.
The government said it would lend support.
Japanese Economics Minister Kaoru Yosano told Reuters in an interview that Tokyo may take more fiscal spending measures if economic conditions worsen further, on top of a stimulus package totaling 75 trillion yen ($829 billion).
