NEW YORK/LONDON, Jan 25 (Reuters) - Gold rose toward $1,100 an ounce on Monday, boosted by a combination of dollar drop, crude oil gains and renewed physical buying after last week's sharp losses.
Investor sentiment, however, remained wary ahead of a whole host of market events including option expirations on the COMEX division of the New York Mercantile Exchange and first notice day later this week, the U.S. Federal Reserve's interest rate decision and the State of the Union address by U.S. President Barack Obama both on Wednesday.
"We are having new buying coming into the market, but it looks like there is more downward pressure. It seems that every time gold bounces a bit, it gets sold," said Jonathan Jossen, COMEX gold floor trader.
Gold <XAU=> was at $1,096.70 an ounce by 2:28 p.m. EST (1928 GMT), against $1,091.65 an ounce late on Friday in New York.
U.S. February gold futures <GCG0> settled up $6 at $1,095.70 an ounce.
"There is risk (aversion) interest," said Marc Elliott, an analyst at investment bank Fairfax. "There is probably a level of support at about $1,100 -- it may dip below but not much further for the time being."
A slightly weaker dollar helped bullion prices, after a sharper-than-expected fall in U.S. existing home sales rekindled concerns about an economic recovery. [
]On Friday, gold hit a near five-week low at $1,081.90, bringing its losses for the week to more than 3 percent, after U.S. President Barack Obama's proposal to limit financial risk-taking hit the broader commodities markets.
"The slump of the last week might be considered by some bargain hunters as being an excessive one," said Eugen Weinberg, an analyst at Commerzbank.
There are signs that China, the world's largest gold producer, could move to tighten monetary policy to rein in its booming economy, denting gold's inflation hedge appeal. [
]Robert Prechter, president of Elliott Wave International, said that gold has hit a top and could fall 40 percent from its peak in a deflationary environment. [
]Gold "is over-owned and overvalued and is about to resume a bear market, if hasn't already," said Prechter, the technical analyst known for predicting the 1987 stock market crash.
PLATINUM, PALLADIUM ETFS RISE
Palladium prices rose but were some way off last week's 19-month high at $471.75 an ounce, when the recent launch of U.S. exchange-traded funds fueled investment demand.
Palladium <XPD=> climbed to $440.50 an ounce, versus $430.50 late in New York on Friday.
Spot platinum <XPT=> was last at $1,544.50 an ounce, against $1,546.50. It touched $1,654 last week, its highest since August 2008.
Holdings of ETF Securities' U.S.-based platinum exchange-traded fund <PPLTiv.P> rose 10 percent on Friday, while those of its U.S. palladium product <PALLiv.P> climbed by a third, the company said on Monday. [
]Among other precious metals, silver <XAG=> prices were at $17.11 an ounce versus $16.96 an ounce late on Monday. Prices at 2:28 p.m. EST (1928 GMT)
