LONDON, June 30 (Reuters) - European shares edged up on Wednesday, rebounding after steep falls a day earlier, with volatility expected as the quarter draws to an end, and with some caution lingering over European banks' funding conditions.
By 0826 GMT, the pan-European FTSEurofirst 300 <
> index of top shares was up 0.3 percent at 999.00 points, as investors picked up beaten-down stocks after equities fell to a three-week closing low on Tuesday.Following gains in the last four quarters, the index has lost 7.5 percent in the last three months, putting it on course to post its biggest quarterly decline since the first quarter of 2009.
Analysts said poor macroeconomic data in recent days have added to investor uncertainty over the pace of global economic recovery, prompting cautious trading as the second-quarter draws to a close.
"Markets are very sensitive to any signs that growth is failing. There have been question marks over the big components of global growth such as U.S. consumer demand and Chinese demand... (and) there isn't a lot of good news," said Bernard McAlinden, investment strategist at NCB Stockbrokers in Dublin.
Among individual movers, AstraZeneca <AZN.L> rose 9.7 percent after a U.S. judge ruled that the patent on its multibillion-dollar cholesterol fighter Crestor was valid, handing the drugmaker a huge victory. [
]Banks were broadly higher, with BNP Paribas <BNPP.PA>, BBVA <BBVA.MC> and Deutsche Bank <DBKGn.DE> up 1 to 1.9 percent, ahead of a 442 billion euros ($540.8 billion) repayment to the European Central Bank (ECB) on Thursday, which could potentially cause a liquidity shortfall of more than 100 billion euros in the financial system.
Markets will closely watch an ECB funding operation on Wednesday to get the first indication of how dependent banks still are on emergency loans.
Across Europe, Britain's FTSE 100 <
>, Germany's DAX < > and France's CAC 40 < > rose 0.2 to 0.4 percent. The Thomson Reuters Peripheral Eurozone Countries Index <.TRXFLDPIPU> added 0.8 percent.The Euro STOXX 50's <
> traded at 2,570.9 points, below its 23.6 percent Fibonacci retracement of around 2,585 from a high in April to a low in May, a move which signals more losses, analysts said.
PORTUGAL TELECOM RISES
Among other movers, Portugal Telecom (PT) <PTC.LS> rose 5.4 percent, after Spain's Telefonica <TEF.MC> raised its offer for PT's stake in Brazilian mobile phone company Vivo <VIVO4.SA>. Telefonica added 0.7 percent.
On the downside, Austrian utility Verbund <VERB.VI> shed 5.6 after the company said it planned a 1 billion euro ($1.22 billion) share issue.
Later in the session, investors will focus on a private sector jobs report from the United States, due at 1215 GMT, to gauge the pace of recovery in the world's largest economy.
In Britain, house prices rose just 0.1 percent on the month in June, down from a 0.5 percent rise in May, the Nationwide building society said on Wednesday, in a further sign that the housing market recovery is cooling. [
]Highlighting the bumpy road ahead for economic recovery, Bank of England policymaker Adam Posen said that the British economy is in a tentative recovery but could still switch back to recession. [
