LONDON, Aug 9 (Reuters) - Strong commodity stocks helped drive Britain's top share index higher by midday on Monday, buoyed by firmer oil and metals prices, while banks also notched up good gains, rallying after falls in the previous session.
By 1110 GMT, the FTSE 100 <
> was up 76.39 points, or 1.4 percent, at 5,408.78, after it closed down 0.6 percent on Friday."We are seeing a lot of speculative buys on optimism that the Fed, when they start meeting tomorrow, will announce some extra stimulus measures to help maintain the U.S. recovery," said Joshua Raymond, market strategist at City Index.
Miners advanced, bouncing back in the wake of declines in the previous session, buoyed by metals prices boosted by a softer U.S. dollar.
Lonmin <LMI.L> and Antofagasta <ANTO.L> were the best off, both up 1.9 percent.
Among integrated oil stocks, BP <BP.L> was the top performer, rising 1.8 percent, after it said on Sunday its pressure testing shows it has "an effective cement plug" on its Macondo oil well in the Gulf of Mexico.
Royal Dutch Shell <RDSa.L> and BG Group <BG.L> both added 1.3 percent, as the crude price <CLc1> climbed 1.1 percent.
Oil services firm Petrofac <PFC.L> rose 1.9 percent after it was awarded a $430 million contract by Kuwait Oil Company.
BANKS BOUNCE BACK
Banks, which reported results last week, were higher as a sector, recovering after Friday's falls. Barclays <BARC.L> put on 2.4 percent, HSBC <HSBA.L> and Standard Chartered <STAN.L> both added 1.4 percent, while Lloyds Banking Group <LLOY.L> rose 1.1 percent.
Royal Bank of Scotland <RBS.L>, however, missed out on the rally, shedding 1.2 percent.
Buyers also came in for insurers. Legal & General <LGEN.L> grabbed the top spot on the blue-chip leader board, up 3.3 percent, boosted by a price target hike from Deutsche Bank in the wake of its first-half results last week.
Old Mutual <OML.L>, which also posted first-half results last week, added 2.4 percent, aided as UBS lifted its target price for the firm.
And Aviva <AV.L> rose 2.2 percent as both BofA Merrill Lynch and Panmure Gordon lifted their target prices for the company following its first-half results last week.
Prudential <PRU.L>, set to unveil its first-half results on Thursday, put on 2.6 percent.
Fund firm Schroders <SDR.L> climbed 2.8 percent after BofA Merrill Lynch lifted its target price after last week's first-half results.
International Power <IPR.L> advanced 2.5 percent. The British utility and French rival GDF Suez <GSZ.PA> could announce an agreement on a planned asset tie-up in coming days, British newspapers reported on Sunday, with both companies due to report first-half results on Tuesday.
U.S. stock index futures <DJc1> <SPc1> pointed to a higher open for Wall Street on Monday. After Friday's U.S. July jobs report, investors will only have the U.S. July employment index data to digest on Monday.
All eyes will be on the latest Federal Reserve rate decision, due after the London market close on Tuesday, although no change is expected to U.S. monetary policy yet. (Editing by Jon Loades-Carter)
