TOKYO, Jan 7 (Reuters) - Gold edged lower on Monday as falls in oil prices and concerns over the U.S. economy after weaker-than-expected U.S. jobs data prompted sales, but sentiment was bullish with investors keen to buy on dips.
Investors sold to lock in their profits as cash gold has gained more than 10 percent over the last month, but the weak dollar outlook and lingering geopolitical tensions are likely to keep the precious metal well-supported.
"It's about time that investors took profits in gold as uncertainty in financial markets was growing after U.S. jobs data," said Shuji Sugata, manager at Mitsubishi Corp Futures and Securities in Tokyo.
"But there is no need to be overly worried as many still believe that long-term sentiment for gold was bullish as there are plenty of reasons to hold gold."
Cash gold was weighed by falls in Japanese gold futures, but still close to last week's historic high of $869.05 ounce.
As of 0322 GMT, spot gold <XAU=> was at $857.10/857.90, down from $862.00/862.70 late in New York on Friday.
Psychological support for gold is seen at $850, Sugata said, with the five-day moving average also seen at $854.
COMEX gold futures extended losses in Asia after falling in New York on profit-taking on Friday. The most active February contract <GCG8> was trading down $5.50 or 0.6 percent at $860.20 from the New York settlement.
The benchmark December gold contract on the Tokyo Commodity Exchange (TOCOM) <0#JAU:> closed the morning session at 3,037 yen a gram, down 18 yen or 0.6 percent from 3,055 yen on Friday.
TOCOM will extend trading by two hours to 5:30 p.m. (0830 GMT) from Monday.
DOLLAR FALL
On Friday, the dollar tumbled after a U.S. government report showed that employers added a scant 18,000 jobs in December and the national unemployment rate kicked up to 5 percent, its highest level in more than two years.
Oil prices extended their losses on Monday, which also put pressure on precious metals.
U.S. crude futures fell on Monday as the market weighed OPEC's comments on the price outlook against bleak U.S. employment data.
NYMEX crude for February delivery <CLc1> fell 65 cents to $97.26 a barrel in Globex electronic trading. U.S. oil closed $1.27 lower at $97.91 on Friday, slipping further from the record high of $100.09 struck on Jan. 3 after poor U.S. jobs data heightened concerns about the health of the economy.
Cash platinum <XPT=> was dragged down by falls in key TOCOM platinum futures <0#JPL:>, which fell by nearly 1 percent.
Platinum fell to $1,535/1,540 an ounce from $1,541/$1,545 in New York on Friday.
Palladium <XPD=> was little changed at $365/369 an ounce from $365/$368 in New York.
