LONDON, Oct 17 (Reuters) - European shares jumped in early trade on Friday, tracking gains in the United States and Asia, as investors picked up battered banks and energy shares were lifted by a rise in crude.
At 0839 GMT, the FTSEurofirst 300 <
> index of top European shares was up 2.7 percent at 881.34 points.Oil groups BP <BP.L>, Total <TOTF.PA> and Shell <RDSa.AS> climbed 4.9-5.7 percent as crude rose nearly $1.70 to $71.50 a barrel amid growing expectations of an OPEC production cut.
Italian bank UniCredit <CRDI.MI> jumped 11 percent after Libyan interests said they held a small stake in the group.
Intesa SanPaolo <ISP.MI> and HSBC <HSBA.L> gained 1.9 and 1.4 percent respectively.
The FTSEurofirst 300 index rose 10 percent on Monday and 3 percent on Tuesday, helped by efforts by governments to thaw interbank lending, but suffered falls of 6.5 percent and 5 percent on the next two days as fears of a recession took grip.
"This is the most volatile week we've seen," said Thierry Lacraz, strategist at Swiss bank Pictet in Geneva. "The sole intelligent thing is to remain on the sidelines and not make any huge bets."
"The global economic environment is still very negative, especially in the United States, where we've seen a dramatic drop in industrial production," he said.
But he added that falling oil prices -- crude is now at half the price it was in July -- would boost sectors like retail, and the reduction in interbank rates would be positive for October.
Across Europe, Britain's FTSE <
>, Germany's DAX < > and France's CAC < > posted gains of 2.2-3.5 percent.
TECHS JUMP ON IBM, GOOGLE
The DJ Stoxx European technology index was the top sectoral percentage gainer, jumping 6 percent, after Internet search and advertising group Google <GOOG.O> defied the economy to beat forecasts, and tech services group IBM <IBM.N> said it would meet long-term goals.
Handset makers Ericsson <ERICb.ST> and Nokia <NOK1V.HE> led the way in Europe, rising 6.3 and 8.8 percent. Nokia posted a fall in third-quarter earnings on Thursday but sounded a reassuring note about cellphone volumes for the full year.
Shares in auto group Daimler <DAIGn.DE> jumped 7.6 percent after sources said private equity group Cerberus was in talks to buy Daimler's remaining stake in Chrysler. Daimler declined to comment.
BMW <BMWG.DE> jumped 5.4 percent and Renault <RENA.PA> 3 percent on Goldman Sachs upgrades.
The FTSEurofirst 300 has fallen 17 percent so far this month, on track for its worst month on record.
The index has been sideswiped by a credit market crisis that piled up losses at big banks, froze interbank lending and slowed the economy. It is down more than 40 percent this year, also the worst on record.
The benchmark now trades at a price to earnings ratio of 7.5 on a one-year forward basis, a valuation many analysts say is undemanding. Dividend yield is at 6 percent.
Analysts said the gyrations of markets afforded some opportunities.
"Selling volatility is an intelligent strategy; some of our clients are selling calls," said Pictet's Lacraz. (Editing by David Cowell)
