LONDON, May 19 (Reuters) - Gold rose in Europe on Tuesday, holding around the $920 mark, in tandem with rising oil prices which hit a 6-month high above $60 a barrel [
].Dollar weakness against the euro and a basket of six leading currencies <.DXY> also underpinned bullion -- making it cheaper for non-U.S. buyers. But stronger global stock markets limited gains, taking heat out of its role as a refuge from turmoil.
Spot gold stood at $921.10 per ounce <XAU=> by 1030 GMT compared with $917.20 quoted late in New York on Monday. The market touched a one week low on Monday at $915.05.
While the prices of some raw materials have moved lock-step with sentiment on stock markets, some investors have plugged into gold to hedge equally against potential for the positive mood to sour and inflationary problems posed by quantitative easing.
"Broadly what we've seen is an increase in non-commercial long positions from tactical investors and broader currency related movements," said Suki Cooper, analyst at Barclays Capital.
She cited CFTC data for the week ending May 12, showing non-commercial positions in U.S. Comex gold futures rising primarily on the back of fresh long positions being established.
"There is also some positioning from a longer term inflationary perspective," she added.
Global share prices extended gains <.MIWD00000PUS>, with a stronger than expected improvement in German economic sentiment encouraging investors to make more forays into so-called riskier assets.
The Mannheim-based ZEW economic think tank's monthly poll of economic sentiment rose to 31.1 from 13.0 in April, in a possible signal that the economic crisis may be abating.
But a separate gauge of current conditions fell to -92.8 from -91.6, registering its weakest reading since July 2003. [
]SHORT-TERM WOBBLE?
April data on U.S. housing starts and building permits is due at 1230 GMT on Tuesday, which economists think will show housing starts rose to 0.52 million from 0.51 million in March, according to a Reuters poll.
On Friday bullion hit a seven-week high of $933.65 per ounce after data showed U.S. core inflation in April rose more than expected.
But short-term, the market could see some seepage after several failed attempts to capture and hold the $925 mark.
"Gold was overbought and failed in the low $930s again yesterday, so needs a correction," said Simon Weeks, director of gold sales at Scotia Mocatta in London.
U.S. gold futures for June delivery <GCM9> inched up 0.1 percent to $921.60 per ounce, compared with Monday's settlement of $921.70 an ounce on the COMEX division of the New York Mercantile Exchange.
Investors have been neither adding or withdrawing money from gold-backed funds in the past few days, with holdings at the world's largest gold-backed ETF, SPDR Gold Trust <GLD>, unchanged at 1,105.62 tonnes from May 18. [
]Spot platinum <XPT=> rose to $1,135.00, boosted by news that U.S. President Barack Obama on Tuesday would propose the most aggressive increase in U.S. auto fuel efficiency ever -- a move that could lift prospects for the metal's usage to clean auto emissions.
The policy initiative would directly regulate emissions for the first time and resolve a dispute with California over cleaner cars. [

].Its silver-backed product, meanwhile, rose again, up 0.7 percent to a fresh record level of 19.262 million ounces. The product's holdings have risen nearly 1.5 million ounces in the last two weeks.
Spot silver was quoted at $13.89 an ounce <XAG=> from $13.72 late on Monday, while palladium was at $230.00 compared with $226.50 <XPD=>.
