NEW YORK, Jan 23 (Reuters) - A raft of weak economic data in Europe lifted the dollar to a six-week high against the euro on Friday and knocked European stocks to a six-year low, while U.S. stocks were mixed after the previous session's sharp losses.
Weak corporate earnings and jitters over the year's outlook put a damper on U.S. stocks. Technology shares darted in and out of positive territory on results at Internet leader Google <GOOG.O> that beat expectations and the S&P 500 turned higher.
Longer-dated U.S. and euro zone government bonds fell on the looming impact of large amounts of new debt to fund the U.S. government's expected economic rescue plans.
The yield on the 30-year U.S. Treasury bond was poised for its biggest weekly gain in more than 26 years due to supply concerns, as well as U.S. criticism this week about the currency policies of China, the largest foreign holder of Treasuries.
Gloomy economic data underpinned shorter-term debt in Europe as investors bet on further interest rate cuts by the European Central Bank. The two-year euro zone government bond yield plumbed to a record low of 1.348 percent at one stage.
With no major U.S. data scheduled, investors took their cue from dismal data coming out of Europe.
The British economy entered recession for the first time since 1991, Spanish unemployment surged to a nine-year high and euro zone services and manufacturing activity shrank in January, albeit at a slower pace, but still recessionary.
Gloom abounded from elsewhere, too. U.S. bellwether General Electric Co <GE.N> posted a 44 percent drop in quarterly profit and the Bank of Japan warned that financial conditions have become tighter even with its key policy rate near zero.
"Sentiment is very fragile," said Darren Winder, strategist at Cazenove.
"People want to believe in economic recovery and want to see some light at the end of the tunnel, but they are finding it very difficult to see that when you have got a banking system which is still experiencing severe difficulties."
The pan-European FTSEurofirst 300 <
> index of top European shares ended down 0.3 percent at 760.54 points, its lowest close since April 2003. The close was slightly lower than a previous low set on Nov. 21.Insurers were in the doldrums. Swiss Re <RUKN.VX> lost 19.6 percent on worries it could make further write-downs when it reports full-year results on Feb. 19.
Banks also fell, with BNP Paribas <BNPP.PA> off 7.8 percent, the second-biggest drag on the FTSEuropefirst 300, while Axa <AXAF.PA>, the biggest drag, fell 6.7 percent.
U.S. stock ideclines were fueled by worries of how 2009 will fare. GE was off more than 8 percent after the Dow component warned of an "extremely difficult" 2009.
"GE is the bellwether because they operate in almost all segments of the market and there's no segment here that you can really look at and say that looks good," said Paul Mendelsohn, chief investment strategist at Windham Financial Services in Charlotte, Vermont.
"On average companies are saying they expect a very, very challenging year and that's part of what's causing the problem," he said.
Around 1:40 p.m., the Dow Jones industrial average <
> was down 29.63 points, or 0.36 percent, at 8,093.17. The Standard & Poor's 500 Index <.SPX> was up 5.12 points, or 0.62 percent, at 832.62. The Nasdaq Composite Index < > was up 19.16 points, or 1.31 percent, at 1,484.65.The pound and euro fell to session lows after data showed the British economy shrank 1.5 percent in the fourth quarter, far more than analysts had expected and confirming a recession.
The dollar rose against a basket of major currencies, with the U.S. Dollar Index <.DXY> up 0.44 percent at 85.86. Against the yen, the dollar <JPY=> was up 0.12 percent at 88.90.
The euro <EUR=> was down 0.42 percent at $1.2929.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 20/32 in price yield 2.67 percent. The 30-year U.S. Treasury bond <US30YT=RR> fell 59/32 in price to yield 3.35 percent.
Oil prices rose on mounting evidence that the Organization of Petroleum Exporting Countries is complying with the bulk of its record output cuts.
The gains came after oil consultant Petrologistics estimated OPEC production would fall by 1.55 million barrels per day in January as part of the cartel's efforts to meet a 2.2 million barrel per day reduction agreed in December.
U.S. light sweet crude oil <CLc1> rose $1.74 to $45.41 a barrel.
Spot gold prices <XAU=> rose $39.45 to $896.00 an ounce.
The MSCI index of Asia-Pacific stocks outside Japan <.MIAPJ0000PUS> fell 2.4 percent to the lowest since Dec 5, while Japan's Nikkei share average <
> finished at a two-month low, down 3.8 percent. (Reporting by Leah Schnurr, Nick Olivari and Chris Reese in New York and Ian Chua, Phakamisa Ndzamela, Jane Merriman, Joanne Frearson and Jan Harvey in London; writing by Herbert Lash; Editing by Dan Grebler)
