LONDON, March 5 (Reuters) - European shares snapped a five-day losing streak on Wednesday, powered higher by soaring commodity prices, hopes of an imminent bailout for bond insurer Ambac and encouraging U.S. service sector data.
The pan-European FTSEurofirst 300 <
> ended up 1.66 percent at 1,301.17 points, still leaving it down nearly 14 percent so far this year.Banks and commodity stocks were the top-weighted gainers. HSBC <HSBA.L> rose 2.5 percent, HBOS <HBOS.L> 5.7 percent, Societe Generale <SOGN.PA> 3.3 percent and BNP Paribas <BNPP.PA> 2.5 percent.
Oil hit a new record at $104.56 a barrel after a large, unexpected fall in U.S. crude stocks and heightened tensions in South America. Index heavyweight oil stocks BP <BP.L>, Total <TOTF.PA> and Royal Dutch Shell <RDSa.L> by 1.7 to 2.2 percent.
Miners tracked copper prices higher. Anglo American <AAL.L> rose 3.3 percent, Kazakhmys <KAZ.L> 5.4 percent and Vedanta <VED.L> 3.2 percent as copper rose to its highest since May 2006.
The U.S. service industry shrank for a second month in February, though at a slower pace. The Institute for Supply Management's non-manufacturing index came in at 49.3, above the record-low 44.6 in January.
"This takes some of the intense recession fears out," said NCB Stockbrokers investment strategist Bernard McAlinden, adding that the bond insurer issue was part of a broader process of accounting for losses related to a meltdown in subprime mortgages, which has driven banks to take massive writedowns.
"The subprime attribution process is making good progress, with $180 billion owned up to. That leaves a fat tail, but it will probably be thinly spread across the world," he said.
McAlinden said he preferred financial institutions with diversified portfolios such as German insurer Allianz <ALVG.DE>, French bank Credit Agricole <CAGR.PA>, Italian lender UniCredit <CRDI.MI> and German groups Postbank <DPBGn.DE>, Commerzbank <CBKG.DE> and Munich Re <MUVGn.DE>.
Credit Agricole gained 5.8 percent as dealers said relief that France's biggest retail bank was not planning any big acquisitions outweighed concerns over its fourth-quarter loss.
Across Europe, Germany's DAX <
> jumped 2.1 percent, France's CAC 40 < > rose 1.7 percent and Britain's FTSE 100 < > advanced 1.5 percent despite a clutch of stocks going ex-dividend.FOCUS SHIFTS AFTER AMBAC
After European markets closed, shares in Ambac were halted with news pending and a person briefed on the matter said it was set to announce a capital infusion.
Investors' focus will next shifts to rate decisions from the European Central Bank and the Bank of England on Thursday.
NCB's McAlinden said he expected the ECB to stay put at 4 percent, noting that Eurozone services data was not weak enough to push the ECB into action but also that the bank would have to be "cautious about not looking too hawkish at the same time".
A Reuters poll last week showed economists expect the ECB to cut rates twice this year, but the chance of an imminent move looked less likely with growth resilient and inflation high.
While the ECB has held its fire, the U.S. Federal Reserve has served up 125 basis points in cuts so far this year and is expected by many economists to provide another big reduction on March 18.
Its cuts in January helped spark a rise in global stocks, termed a bear market rally by many analysts.
Among other major movers, British drugs group GlaxoSmithKline <GSK.L> fell 2.6 percent after U.S. health officials said they had requested more information from the company and other makers of asthma drugs to evaluate safety.
The euro hit a record high against the dollar at above $1.53, a move that analysts say will hurt European earnings.
"A strong euro versus both the U.S. dollar and the British pound suggests that regionally U.S. equities should continue outperforming European ones, and that within Europe, UK should outperform the eurozone," JPMorgan said in a research note.
"In relative terms, every 1 percent strengthening of the euro versus the dollar points to U.S. earnings beating European ones by 0.25 percent, on our estimates." JPMorgan said. (Additional reporting by Peter Starck in Frankfurt; Editing by David Holmes)
