LONDON, March 2 (Reuters) - Britain's leading shares gained 0.8 percent by midday on Tuesday, buoyed by firmer commodity issues and by banks, with HSBC <HSBA.L> recovering its poise after sell-offing in the prior session on disappointing results.
At 1158 GMT, the FTSE 100 <
> index was 44.39 points higher at 5,450.33, close to a six-week peak."The move through 5,400 in recent days is another hurdle passed and leaves us looking at the highs for the year, with 5,600 as the obvious target," said Anthony Grech, market strategist at IG Index.
"It could well be a bumpy ride but for now investors seem happy to position themselves for more gains," he said.
Banks were the best performing blue-chip sector, with HSBC recovering 1.6 percent after its sharp fall on Monday which followed below-forecast results.
Standard Chartered <STAN.L>, set to post full-year numbers on Wednesday, advanced 2.2 percent, while Royal Bank of Scotland <RBS.L>, Lloyds Banking Group <LLOY.L> and Barclays <BARC.L> gained 1.6-3.0 percent.
Oil majors also provided support for the blue chips, with Royal Dutch Shell <RDSa.L>, BG Group <BG.L>, Cairn Energy <CNE.L> and Tullow Oil <TLW.L> adding 0.2-0.8 percent as the crude price <CLc1> pushed back towards $79 a barrel.
BP <BP.L>, however, slipped 0.1 percent. The company is to form a joint venture with privately owned Lewis Energy to exploit Lewis's Eagle Ford shale gas assets, in a deal worth around $200 million, a source familiar with the matter said.
Miners were higher. Mexican silver miner Fresnillo <FRES.L> stood out, gaining 2.0 percent after posting a forecast-beating 141 percent rise in 2009 profit on higher prices and stronger output. [
]Elsewhere, a slight dip by metals prices was offset by a bullish review from Nomura, which raised targets across the sector. Anglo American <AAL.L>, Rio Tinto <RIO.L>, BHP Billiton <BLT.L> and Antofagasta <ANTO.L> added 0.3-0.8 percent.
But Vedanta Resources <VED.L> missed out, shedding 3.8 percent after launching a $775 million convertible bond issue.
Among individual gainers, British Airways <BAY.L> rose 4.2 percent following positive results from fellow carriers Continental Airlines <CAL.N> and Lufthansa <LHAG.DE>, while an industry body said the recovery in global demand for air traffic was gathering pace.
Chipmaker ARM Holdings <ARM.L> also saw good support, ahead 3.3 percent and supported by an upbeat outlook statement from SanDisk <SNDK.O> and by a bullish note on the sector from UBS.
U.S. stock futures <
>, <SPc1>, <NDc1> pointed to a higher open on Wall Street on Tuesday after good gains in the previous session helped by the SanDisk results.
PRU PRUNED
Life insurer Prudential <PRU.L> was the biggest blue-chip loser, down 6.1 percent, extending Monday's falls following its move to buy American International Group's <AIG.N> Asian arm for $35.5 billion, funded by a $21 billion rights issue.
Motor insurer Admiral Group <ADML.L> was also under pressure, down 2.3 percent after in-line full-year results failed to excite, with KBC Peel Hunt prompted to cut its rating to 'hold' from 'buy'. [
]Sterling remained a drag on investor sentiment as the currency recovered slightly but still remained jittery after hitting a 10-month low on Monday on concerns the pending British general election would result in a hung parliament.
Polls over the weekend suggested Gordon Brown's ruling Labour party may just hang on for another term, as the opposition Conservatives saw their lead cut back, with neither looking likely to secure a parliamentary majority.
