LONDON, Oct 30 (Reuters) - European shares extend their rally into a third day on Thursday, as financials were boosted by strong Deutsche Bank <DBGKn.DE> results and miners tracked a rise in commodities as the dollar weakened.
At 0956 GMT, the FTSEurofirst 300 <
> index of leading European shares was up 1 percent at 905.96 points, having surged 7.5 percent on Wednesday.It is still down nearly 40 percent in 2008, battered by a global credit crisis and the resulting economic slowdown. The U.S. Federal Reserve cut interest rates by 0.5 percentage points on Wednesday. Japan's Nikkei index <
> closed up 10 percent on Thursday on talk of a likely rate cut."This is a fantastic rally, but it is only a rally. It's like the Grand Old Duke of York. We've marched up the hill, but we'll probably march down, or maybe fall down just as quick," said Justin Urquhart Stewart, director at Seven Investment Management.
"The rate cuts are encouraging. But we're dealing with a slump. It's not a matter of whether it's bad. It's a matter of how bad."
Across Europe, Britain's FTSE 100 <
>, Germany's DAX < > and France's CAC-40 < > were 0.4-1.4 percent higher.Deutsche Bank jumped 17 percent as investors cheered surprisingly strong third-quarter net profit from Germany's largest bank, as well as indications it will not have to raise capital in the near term.
Banks added most to the index. Commerzbank <CBKG.DE> and UBS <UBSN.VX> were up 7.8 and 3.1 percent, respectively.
MINERS GAIN
A weaker dollar boosted metals prices, pushing miners Anglo American <AAL.L>, Antofagasta <ANTO.L>, BHP Billiton <BLT.L>, Rio Tinto <RIO.L> and Xstrata <XTA.L> up between 3.8 and 7.7 percent.
Crude <CLc1> rose 2.2 percent to $68.95 a barrel, but oil stocks fell. BP <BP.L> was down 1 percent, having closed at an eight-week high on Wednesday. Total <TOTF.PA> and ENI <ENI.MI> were down 2.7 percent.
Royal Dutch Shell <RDSa.L> fell 2 percent, despite beating all forecasts with third-quarter current cost of supply (CCS) net profit up 71 percent at $10.9 billion. High oil prices and asset sales outweighed a 7 percent drop in its oil and gas production.
Among a raft of other companies reporting results, consumer goods giant Unilever <ULVR.L> was up 2 percent after posting a rise in third-quarter underlying sales at the top end of forecasts and upgrading its 2008 sales outlook.
Insurer Standard Life <SL.L> was down 5.4 percent after it said sales were flat for the first nine months of 2008.
Irish drugmaker Elan <ELN.I> was 18 percent lower, having fallen 48 percent earlier. Its marketing partner Biogen Idec <BIIB.O> said on Wednesday it had notified regulators of a new case of a potentially deadly brain disease in a multiple sclerosis patient being treated with Elan's Tysabri product.
