LONDON, July 17 (Reuters) - European shares rose for the fifth straight day on Friday led by banks and commodity stocks ahead of earnings from Citi <C.N>, Bank of America <BAC.N> and General Electric <GE.N>.
By 0800 GMT, the FTSEurofirst 300 <
> index of top European shares was up 0.5 percent at 871.06 points, after hitting its highest closing level in a month on Thursday.The index was up 7.1 percent this week, on track to post its best weekly gains since late November last year. Banks were among the top gainers, with Deutsche Bank <DBKGn.DE>, Banco Santander <SAN.MC>, Societe Generale <SOGN.PA>, HSBC <HSBA.L> and Royal Bank of Scotland <RBS.L> up 0.6-1.4 percent.
Swedbank <SWEDa.ST> reversed earlier losses to trade up 3.3 percent despite posting a bigger-than-expected second quarter operating loss, hurt by huge provisions for souring credits in the recession-hit Baltic region.
"The market is looking for good news and it is interpreting everything as good news. Whether it is interpreting it correctly, I am not too sure," said Justin Urquhart Stewart, director at Seven Investment Management. "However, their (interpretation) skills may be challenged over the next few weeks... although the banking figures will show banks are doing well, the global economy is still slow," he said. "We are going to come out of recession in the next two quarters and go into a dull grey world."
Commodity stocks also traded higher, with BP <BP.L>, Royal Dutch Shell <RDSa.AS> and Total <TOTF.PA> rising 0.3-0.9 percent.
In the mining sector, BHP Billiton <BLT.L>, Rio Tinto <RIO.L>, Anglo American <AAL.L> and Xstrata <XTA.L> took on 0.8-2.2 percent.
U.S. stocks rallied for a fourth day on Thursday after JPMorgan's <JPM.N> strong results fed growing optimism about the quarterly earnings season and technology shares rose in anticipation of more good news.
IBM <IBM.N>, after the market close, sharply raised its full-year earnings forecasts as it benefits from focusing more on higher-margin businesses in software and services.
Google's <GOOG.O> quarterly profit also beat Wall Street expectations, but the weak economy and slump in advertising spending took a toll on revenue growth and the price of its search ads.
In Europe, Alcatel-Lucent <ALUA.PA>, ASML <ASML.AS>, STMicroelectronics <STM.PA> and Infineon <IFXGn.DE> were up 0.6-3.1 percent.
Heavyweight Nokia <NOK1V.HE>, however, was down 2.8 percent, extending Thursday's 15 percent drop after the world's top cellphone maker cut its profitability and market share forecasts due to tough competition at the top end of the market.
Across Europe, Britain's FTSE 100 <
> added 0.6 percent, Germany's DAX < > rose 0.9 percent and France's CAC 40 < > gained 0.6 percent.
LOOKING UP
UBS lifted its year-end target for the FTSEurofirst 300 to 1,000 from 900, or an increase of nearly 15 percent from current level, as it expected a turn in the earnings cycle.
"We believe that after 1-1/2 years, we are approaching an end to the earnings downgrades given: earnings momentum has risen sharply; consensus estimates for 2009 have halved over the last nine months and; the macro backdrop continues to improve," Nick Nelson, UBS's European equity strategist said in a note.
On the downside, French group Accor <ACCP.PA> sank 7.8 percent after it posted a 9 percent drop in second quarter sales as the economic crisis weighed on its hotel business despite slight growth in its prepaid services division.
Carrefour <CARR.PA>, the world's second-biggest retailer behind U.S. group Wal-Mart <WMT.N>, lost 2 percent after saying second-quarter sales fell 1.2 percent, hurt by weaker western European markets, lower petrol prices and exchange rates. (Editing by Mike Nesbit)
