LONDON, April 4 (Reuters) - European shares rose in a volatile session on Friday, led by a rally in mining shares and UBS <UBSN.VX>, which came under pressure to break up, while a surprisingly large fall in U.S. jobs data capped gains.
The FTSEurofirst 300 index <
> of top European shares ended 0.5 percent higher at 1,318.4 points.The index rose 4.1 percent this week, making this its best weekly performance in over a year, thanks to a 5 percent rally in bank stocks <.SX7P> after UBS unveiled large first-quarter writedowns to purge its books of any assets linked to the slumping U.S. housing market.
Banks were mixed on Friday, although UBS was among the top individual gainers, rising by more than 3 percent, after former chief executive Luqman Arnold pushed to break up the Swiss bank.
But the focal point for investors was the U.S. employment report, which showed 80,000 jobs were lost in March, making this the third consecutive decline and the largest drop in five years. Forecasts were for a fall of 60,000.
"The market is already anticipating in the short term that the news is going to be bad, we can now write off the first half of this year in terms of anticipating any growth," said Henk Potts, a strategist with Barclays Wealth.
"The big question for investors is have the aggressive interest rate cuts from the Fed and the stimulus packages coming through ... been enough to generate a bounce-back in the broader economy in the second half?" he said, adding Barclays Wealth believed they were.
The Federal Reserve has cut U.S. rates by 200 basis points to 2.25 percent to avert widespread deterioration in growth because of the ongoing credit crisis. The FTSEurofirst has fallen by about 13 percent so far this year as concern has grown over the potential for recession in the United States.
"This will put the focus back on the economic reality and get us back to a more gloomy point of view. We've seen a fantastic rally this week led by banks and retailers," said IG Index analyst David Jones.
The European market posted its worst quarterly loss in five and a half years in the first three months of this year, dragging down by the size of the mounting losses at investment banks linked to subprime lending.
Rio Tinto shares <RIO.L> were the top weighted gainers on the broader European market on Friday after Chief Executive Tom Albanese said the company's portfolio of growth projects would drive its shares up faster than those of its rival BHP Billiton <BLT.L>, undermining the case for BHP's all-stock hostile takeover offer.
Rio shares rose 4.6 percent while BHP shares were up 3.6 percent.
Rising base metal prices helped push up Xstrata <XTA.L> by 3.6 percent and Anglo American <AAL.L> by 2.4 percent.
British Energy jumped more than 7 percent on a media report that EDF planned a bid, making it the top percentage gainer in Europe. Sources familiar with the matter told Reuters EDF is expected to submit a non-binding offer for British Energy, which is in talks with several companies about a possible sale or partnership.
British Energy declined to comment, while EDF reiterated it was keen to take part in the development of nuclear power generation in Britain.
