LONDON, Feb 23 (Reuters) - European shares edged down on Tuesday, with weakness in banks offsetting gains in food producers, while Carlsberg <CARLb.CO> rose after upgrading its medium-term profit margin guidance.
By 1037 GMT, the FTSEurofirst 300 <
> index of top European shares fell 0.5 percent to 1,018.50 points, having closed 0.3 percent lower on Monday as equities snapped a five session gaining run.Banks were on the backfoot, with Barclays <BARC.L>, Societe Generale <SOGN.PA>, BNP Paribas <BNPP.PA> and Deutsche Bank <DBKGn.DE> off 0.7 to 1.9 percent.
Commerzbank <CBKG.DE> fell 7.1 percent with the lender expecting a difficult 2010 after posting a worse-than-expected fourth-quarter loss, hit by weak trading results and higher loan loss provisions. [
]Investors confidence was shaken by data showing that German business sentiment unexpectedly fell in February, according to the Munich-based Ifo think tank, dealing a blow to the recovery prospects of Europe's largest economy. [
]Some nervousness was also expected ahead of testimony by Federal Reserve chairman Ben Bernanke on Wednesday and Thursday, which is expected to shed light on how soon key U.S. rates may start to rise, after the surprise increase last week in the rate the Fed charges banks for emergency loans. [
]"Bernanke and his fellow policymakers have made it clear that this is not the start of moving the base rates up. We have had a rebound in GDP but that was all due to inventories and government stimuli and if you take these out you still have an economy that is contracting," said Koen De Leus, economist at KBC Securities.
Later in the session, investors will look at U.S. data, including a consumer confidence reading and the S&P/Case-Shiller index, which gives an indication of house price trends.
Oil majors were also under pressure, with crude prices breaking a five-day rally. BP <BP.L>, BG <BG.L>, Total <TOTF.PA> and ENI <ENI.MI> shed 0.1 to 0.9 percent.
CARLSBERG SURGES
Among individual movers, Carlsberg rose 8.3 percent, hitting a 17-month high after the brewer reported fourth-quarter operating profit a touch below expectations and said it sees 2010 operating profit in line with 2009. Analysts cheered its move to raise its medium-term operating margin forecast. [
]Peer Heineken NV <HEIN.AS> added 2.5 percent after the world's third-largest brewer forecast lower beer consumption in many regions, limited price increases and few cost benefits this year after 2009 results were broadly in line with expectations.
Among other individual fallers, Merck KGaA <MRCG.DE> fell 6.8 percent after the world's largest maker of chemicals for flat screens gave a cautious 2010 outlook well below market forecasts and cut its dividend reflecting uncertainty over its drugs pipeline. [
]Food producers reversed weakness from the previous session to rise across the board. Danone <DANO.PA>, Unilever <ULVR.L> and Nestle <NESN.XV> rose 0.2 to 1.2 percent.
Across Europe, Britain's FTSE 100 <
> was flat, while Germany's DAX < > and France's CAC 40 < > fell 0.5 and 0.2 percent respectively.The FTSEurofirst 300 index has gained 59 percent since hitting a low in March, but is down close to 2 percent in 2010 partly due to sovereign debt worries in euro zone peripheral countries.
