LONDON, Oct 17 (Reuters) - Britain's top share index gained 2 percent by midday on Friday in volatile trade, with gains in energy and bank stocks outweighing falls in the beleaguered mining sector.
By 1107 GMT, the FTSE 100 <
> was up 95.0 points at 3,956.4 after closing 5.4 percent lower on Thursday. The index has lost 19 percent in October, on track for its biggest monthly fall since the 1987 crash and is down 38.7 percent this year.Energy stocks were among the biggest gainers with oil <CLc1> prices recovering to trade above $70 per barrel as rising equity prices lifted hopes for demand and on growing expectations of an OPEC production cut. <BP.L> gained 4.5 percent, while Royal Dutch Shell <RDSa.L> rose 6 percent.
But heavily sold miners were the victim of falling metals prices and forced selling by hedge funds, with early gains wiped out. Xtrata <XTA.L>, Kazakhmys <KAZ.L> and Lonmin <LMI.L> fell between 4.2 and 7.6 percent.
"It's (the market) got a mixed feel about it today, we've had an unravelling of positions by hedge funds in mining stocks, and as negative news has come in they've opened short positions," said Paul Mumford, senior fund manager at Cavendish Asset Management.
Battered banks were broadly higher, with investors slightly more positive on the struggling sector. HSBC <HSBA.L> gained 1 percent and Lloyds TSB <LLOY.L> rose 3 percent.
"Equities look attractive on a two- to three-year time horizon and people are beginning to extend their horizons beyond the current measures to support the banking system," said John Haynes, senior equity strategist at Rensburg Sheppards.
"Investors are looking to pick up value as they are thinking enough has been done to achieve those aims."
The chairman of Britain's financial regulator, Adair Turner, said on Friday that the global banking system is past the danger of systemic meltdown following government intervention, but there will still be economic consequences.
Other financial stocks were also in positive territory with interdealer broker ICAP <IAP.L> gaining 4.4 percent and insurer Standard Life <SL.L> adding 0.4 percent, while Old Mutual <OML.L> gained 1.2 percent. Prudential <PRU.L> lost 4.5 percent after the Financial Times said the company was forced to deny planning an imminent rights issue as worries about the global economy spread to insurers.
Intercontinental Hotels <IHG.L> fell 0.3 percent after JP Morgan cut its price target on the company and other European hotel stocks.
UK property shares fell to their lowest level in almost 5 years. Property services firm Savills <SVS.L> warned of lower profits and worries over rent prospects grew after data this week fanned recession concerns and showed Britain's commercial property downturn was accelerating.
The FTSE 350 Real Estate index <.FTNMX8730> fell as much as 4.9 percent to 2,297 points -- its lowest level since December 2003, according to Reuters data.
British Land <BLND.L> and Land Securities <LAND.L> fell 4.3 and 4.8 percent respectively.
