LONDON, Nov 2 (Reuters) - Buoyant energy stocks drove Britain's top share index higher on Tuesday after earnings from BP <BP.L> and BG Group <BG.L>, while mining stocks provided some support on the back of a rise in metals prices.
By 1213 GMT the FTSE 100 <
> was up 68.14 points, or 1.2 percent, at 5,762.76 in choppy trade as investors awaited the outcome of a two-day U.S. Federal Reserve policy-setting meeting starting on Tuesday.Energy stocks <.FTNMX0530> added the most points to the index, with BP climbing 1.5 percent following third-quarter results. Traders said bad news surrounding its Gulf of Mexico oil spill was well priced in. [
]"I think with regards to BP, a lot of the uncertainty is out of the way and it is slowly but surely getting back to business," Manoj Ladwa, senior trader at ETX Capital, said.
Peer BG Group advanced 2.9 percent after it posted a 12 percent jump in third-quarter net profit and significantly upgraded its Brazilian resources. [
]Miners <.FTNMX1770>, which rose on Monday after stronger-than-expected Chinese manufacturing data, were in demand once again as a weaker dollar supported metals prices.
Antofagasta <ANTO.L> was among the best off, putting on 2.4 percent, with the Chilean copper miner scheduled to release its third-quarter production report on Wednesday.
Aviva <AV.L> rose 1.6 percent as the insurer reported sales for the first nine months in line with expectations and said it was set for "strong profitable growth" in 2010.
EYES ON U.S. EVENTS
Despite the upbeat corporate news flow, investors remained wary ahead of the Fed meeting and U.S. mid-term elections.
At its meeting in Washington, the Fed will consider the prospect of further quantitative easing. Markets are pricing in a commitment to buy at least $500 billion in Treasury debt over the coming months to spur a flagging economy. [
]"The FTSE... has had quite a nice boost obviously from BP... (and it) is doing better this morning than (European indexes) because we haven't got this uptick in fear about the European sovereign debt crisis, which isn't affecting us to the same extent," David Morrison, market strategist at GFT Global, said.
"But it's all short-term stuff. Ultimately we will live or die by what happens in the U.S.," he said.
Imperial Tobacco <IMT.L>, the world's fourth-biggest cigarette maker, rose 3.2 percent after meeting forecasts with an 11 percent rise in annual earnings as price increases offset lower overall sales volumes.
Peer British American Tobacco <BATS.L> climbed 2.4 percent.
Banks <.FTNMX8350> were mixed, with Lloyds Banking Group <LLOY.L> dropping 1.9 percent as concerns over losses from problem loans and tougher competition overshadowed an upbeat trading statement from the part-nationalised British lender.
Royal Bank of Scotland <RBS.L>, due to issue an update on Friday, shed 0.5 percent, while Barclays <BARC.L> slipped 0.3 percent ahead of its update on Nov. 9.
But HSBC <HSBA.L>, set to issue an update on Friday, rose 1.4 percent, with Standard Chartered <STAN.L> up 1.8 percent.
Elsewhere, Serco <SRP.L> slid 4 percent, the top FTSE 100 faller, as investors continued to shun the company that apologised on Monday for asking suppliers to make cash rebates on work for this year or risk losing future contracts.
