By Blaise Robinson
PARIS, July 25 (Reuters) - European stocks ended slightly lower on Friday, after a flurry of better-than-expected U.S. economic data failed to eclipse a profit warning by Munich Re <MUVGn.DE> that knocked insurers lower.
On the upside, Danone <DANO.PA> surged 7.7 percent after the food and beverage group lifted its 2008 operating margin target and confirmed 2008 sales and profit growth outlook.
UBS <UBSN.VX> sank 6.1 percent on the back of news that New York State has filed a lawsuit accusing the bank of deceptively selling auction-rate securities as cash equivalents.
The FTSEurofirst 300 <
> index of top European shares ended 0.1 percent lower at 1,169.59 points, after falling by more than 1 percent during the session.The index, which is down 22 percent so far in 2008, has gained 0.5 percent during the week.
Late in the session, better-than-expected U.S. data reassured investors on the outlook of the world's biggest economy, and spurred a rally on Wall Street.
U.S. consumer sentiment recovered unexpectedly in July, sales of newly built single-family homes were stronger than expected in June, and new orders for long-lasting U.S. manufactured goods rose surprisingly in June on demand for metals, machinery, electrical equipment, and military needs, even though transportation orders were weak.
"Core durable goods shipments increased for the fourth consecutive month, signalling resilient investment in equipment despite a difficult context," Jean-Marc Lucas, economist at BNP Paribas, wrote in a note.
Among the biggest losers, the DJ Stoxx European insurance index <.SXIP> shed 4.3 percent. Munich Re slashed its forecasts for 2008 profit, blaming turbulent equity markets, and Hannover Re <HNRGn.DE> said it will be difficult to reach full-year targets if capital markets do not calm down.
"This is bad news. It shows insurers can't be trusted and that even now they don't have a clear idea what they will make this year," said Michael Huttner, insurance analyst at JP Morgan.
Munich Re tumbled 7.3 percent, Hannover Re shed 7.2 percent, while AXA <AXAF.PA> fell 4.8 percent, Aegon <AEGN.AS> lost 6 percent and Allianz <ALVG.DE> dropped 4.6 percent.
Other sectors were also hit by profit warnings. Belgacom <BCOM.BR> shed 6.9 percent after cutting its revenue forecast for 2008, citing pressure on mobile call prices and a gloomy economic environment.
"There are more profit warnings coming out and they appear to become more severe," said portfolio strategist Andreas Huerkamp at Commerzbank in Frankfurt, adding that he expected earnings to continue to deteriorate in the coming two quarters.
"It looks like especially June and July came in much worse than many management boards expected," he said.
On the upside, energy heavyweights gained ground ahead of their earnings reports due next week and which are expected to show record profits thanks to high oil prices.
BP <BP.L> rose 1 percent, Royal Dutch Shell <RDSa.L> gained 0.4 percent and Total <TOTF.PA> added 1.5 percent.
EDF <EDF.PA> rose 5.6 percent as investors saw the potential acquisition of British Energy <BGY.L> as positive. A source briefed on the matter told Reuters that nuclear operator British Energy agreed to be taken over by the French utility for about 775 pence a share.
Around Europe, Germany's DAX index <
> lost 0.06 percent, UK's FTSE 100 index < > fell 0.2 percent and France's CAC 40 < > gained 0.7 percent. So far this year, the DAX has lost 20 percent, the FTSE 100 has lost 17 percent and the CAC 40 has dropped 22 percent.
