LONDON, Nov 25 (Reuters) - A rebound in commodity prices lifted mining and energy shares, pushing Britain's top share index up 0.6 percent around midday on Wednesday, with equities also helped by optimistic comments by the U.S. Federal Reserve.
By 1214 GMT, the FTSE 100 <
> was up 29.33 points at 5,353.29, retracing Tuesday's losses. Investor sentiment was boosted by the Fed's confidence on the durability of the economic recovery in the United States. [ ]Miners were the biggest gainers, underpinned by a rally in metals prices and a rise in gold <XAU=> to a fresh high.
Among the bigger risers were Randgold Resources <RRS.L>, Anglo American <AAL.L>, BHP Billiton <BLT.L> and Lonmin <LMI>, which rose 2.6 to 2.8 percent.
Earlier data showed that Britain's economy shrank 0.3 percent in the third quarter, from a previous reading of 0.4 percent, and most analysts expect a return to growth at the end of the year. [
]The FTSE has so far rebounded 55 percent since hitting a low in March, and gains so far in November have put the index on track to post its best monthly performance since August.
But Jeremy Batstone-Carr, head of research at Charles Stanley said that the rally on the FTSE was vulnerable to the fact that the recovery in the economy remains shaky and investors were increasingly looking to safe-haven stocks.
"It does not surprise me that it has been the defensive sectors of the market which have begun to show their paces while the more cyclical sectors have begun to lose some form," he said.
Pharmaceuticals, seen as resistant to a weak economy, were higher. AstraZeneca <AZN.L>, GlaxoSmithKline <GSK.L> and Shire <SHP.L> added 1-2.2 percent.
Oil majors also gained, as crude prices <CLc1> edged up above $76 a barrel. BP <BP.L>, BG Group <BG.L> and Royal Dutch Shell <RDSa.L> gained 0.3 to 0.4 percent.
The chief executive of Royal Dutch Shell forecast it would not need to borrow any more money if oil remained around $70 per barrel, the Financial Times reported. [

COMPASS HITS 7-YR HIGH
Among individual stocks caterer Compass Group <CPG.L> added 6.4 percent and hit a 7-year high after reporting a 33-percent jump in full-year pretax profit at the top end of market expectations. [
]International Power <IPR.L> gained 3.4 percent, with traders citing renewed speculation of M&A activity after the Daily Mail reported GDF Suez <SCZ.PA> as a possible bidder for the British power generation firm.
On the downside, hedge fund Man Group <EMG.L> shed 4.2 percent, the top faller on the index, in a further reaction to Tuesday's rating downgrade by Credit Suisse and with the stock trading ex-dividend on Wednesday.
Ex-dividend factors knocked 1.01 points off the blue chip index, with Amec <AMEC.L> and Next <NXT.L> also losing their dividend attractions.
Platinum refiner Johnson Matthey <JMAT.L> lost 2.4 percent after posting a 21-percent drop in first-half pretax profit due to lower precious metal prices and a slowdown in automobile sales. [
].United Utilities <UU.L> shed 1.5 percent after reduced demand for water from recession-hit businesses and inflated costs weighed on its first-half results. [
]A raft of U.S. data is expected later in the session ahead of the Thanksgiving holiday on Thursday, including initial weekly jobless claims, October new home sales and the final reading of the University of Michigan November consumer sentiment numbers.
