FRANKFURT, May 20 (Reuters) - European shares snapped a four-day rally on Tuesday, pulled down by mining and banking stocks, which offset gains in the pharmaceutical sector.
By 0906 GMT, the pan-European FTSEurofirst 300 index <
> was down 0.96 percent at 1,365.10 points. The index rose about 2.5 percent over the past four sessions, mainly helped by commodity stocks.The pan-European index is up about 3 percent since the beginning of the month, but still down 8.5 percent so far this year.
The market offered little reaction to data that showed German investors' view of current economic conditions was better than anticipated in May, although expectations deteriorated more than forecast, according to the ZEW Institute.
The DJ Stoxx banking index <.SX7P>, one of the worst performing sectors in Europe so far this year, has lost about 16 percent year to date. The DJ Stoxx basic resource index <.SXPP> has gained about 20 percent.
Mining stocks fell on Tuesday, with Rio Tinto <RIO.L> down 4.5 percent, BHP Billiton <BHP.L> down 5.6 percent, and Xstrata <XTA.L> falling 4.1 percent.
Ingo Frommen, head of international equities at German bank LBBW, said investors were locking in profits after the sector's recent strong run.
Banking shares fell, led by declines in Royal Bank of Scotland <RBS.L> as the glum mood surrounding the stock and the UK bank sector persisted.
"What you can see in the banking sector is the wheat separating from the chaff. On the one hand, banks which announced plans for rights issues weaken, while others, who performed well in the first quarter, are stronger," said Frommen.
RBS fell 1.5 percent, Credit Agricole <CAGR.PA> fell 1.6 percent, UBS <UBSN.VX> dipped 0.6 percent.
Barclays <BARC.L> fell 1.5 percent after a media report said the bank was considering a takeover bid for a rival and could try to buy an investment bank unit. Barclays was not immediately available to comment.
PHARMA BUCKS THE TREND
On the upside, pharmaceutical stocks bucked the trend, and the DJ Stoxx pharmaceutical sector index <.SXDP>, which is down 10.8 percent since the beginning of the year, was up 1.5 percent on Tuesday, lifted by gains in AstraZeneca <AZN.L>.
The stock climbed after news a U.S. court hearing over patents on its blockbuster schizophrenia drug Seroquel has been brought forward to Tuesday from June 4, boosting hopes the Anglo-Swedish group may prevail in the case.
Vague talk of bid interest from Pfizer Inc <PFE.N> or Schering-Plough Corp <SGP.N> also lent some support to AstraZeneca shares, which rose 3 percent.
GlaxoSmithKline <GSK.L> rose 2 percent.
Investors worked their way through a series of earnings updates, including Britain's second-largest property company British Land <BLND.L>.
British Land shares rose 2 percent after its said sentiment in the property market remained volatile but the rate of decline in property values was slowing.
Oil stayed above $127 a barrel <CLc1>, keeping concern about inflationary pressures on the boil, particularly after data showed surging energy prices boosted German producer price inflation to a 20-month high in April, Federal Statistic Office data showed on Tuesday.
