LONDON, Aug 20 (Reuters) - Gold held near $945 an ounce in Europe on Thursday, up a touch from the previous session as the dollar's retreat from early highs against a basket of currencies boosted interest in the metal as an alternative asset.
Spot gold <XAU=> was bid at $943.90 an ounce at 0842 GMT, against $941.55 an ounce late in New York on Wednesday. U.S. gold futures for December delivery <GCZ9> on the COMEX division of the New York Mercantile Exchange rose $1 to $945.80 an ounce.
"The lower U.S. dollar and higher stocks took the market by surprise yesterday," said Afshin Nabavi, head of trading at MKS Finance. "(Gold) held the $933 level and flew up above $940."
"At the moment, it looks like we will continue trading the range between $930-960," he added. "A confirmed breach of $945 should take us up towards $959, the previous high, provided the weakness in the dollar continues."
The dollar index <.DXY> edged higher early on Thursday, capping gains in the precious metal, though it has since eased back to trade flat from the previous session. [
]Traders are awaiting direction from weekly U.S. jobless claims and the Philadelphia Federal Reserve's business activity index, which will give clues on the state of the U.S. economy later in the session.
On the wider markets, European stocks rose after Chinese shares surged more than 4 percent following a two-week sell-off, but some investors worried the Shanghai slide had more room to run. [
] [ ]Oil prices crept higher, extending the previous session's $2 a barrel gains, as data showing a steep drop in U.S. crude stockpiles and imports supported prices. Gold often tracks crude prices, as the metal can be bought as an inflation hedge. [
] JITTERYInvestors remain jittery about demand after a report from the industry-funded World Gold Council on Wednesday showed a 9 percent drop in second-quarter demand, largely on a fall in jewellery buying.
Holdings of the largest gold exchange-traded fund, the SPDR Gold Trust <GLD>, were unchanged for a sixth straight session on Wednesday, the trust said on its website. [
]Among other precious metals, silver rose more than 1 percent as base metals rallied on the back of rising Chinese equities, helping lift the grey metal, which is used in industries such as electronics manufacturing as well as being an investment asset.
Silver's correlation with copper has increased over the last week to 0.92 -- with 1 demonstrating a perfect correlation -- from 0.61 the previous week, according to Reuters data.
Spot silver <XAG=> was at $14.02 an ounce against $13.79. Elsewhere platinum <XPT=> was at $1,249 an ounce against $1,234.50, while palladium <XPD=> was at $273 against $270.
The main South African miners' union said late on Wednesday it will start an indefinite strike next week at Impala Platinum, the world's second largest platinum producer. South Africa produces four out of five ounces of the metal. [
]Implats said it hopes to hold further talks with the union to prevent the strike. [
]"Platinum for the moment should find further support around the $1,220 level, with scaled-up resistance expected towards the June $1,297 high," said TheBullionDesk.com analyst James Moore.
"Palladium appears comfortable above the $264 level although the scale of recently added longs does leave the metal vulnerable to a deeper correction," he added. (Editing by James Jukwey)
