LONDON, May 13 (Reuters) - Gold dropped more than 2 percent on Tuesday as the dollar extended gains after news of unexpectedly strong core U.S. retail sales in April robbed bullion of some of its appeal as an alternative investment.
Gold's weakness spurred selling in other precious metals.
Platinum fell more than 3 percent -- the day after it jumped to its highest level in almost two months on speculative buying following the launch of U.S. platinum exchange-traded notes.
Spot gold <XAU=> hit a low of $860.90 an ounce, down from $884.60/886.00 late in New York on Monday.
"Gold has been reflecting movements in crude oil and the dollar tick by tick, and the true fundamentals of gold have clearly taken a backstage," said Pradeep Unni, analyst at Vision Commodities Services in Dubai.
"Buying is likely to gather momentum once spot gold scythes $892 levels, but gains could be limited to around $904 to $914," said Unni, adding there was a possibility that gold would revisit the $850 to $841 levels.
The most active June gold futures contract <GCM8> on the COMEX division of the New York Mercantile Exchange fell more than 1 percent to $868.7 an ounce, down $16.2 from Monday's close.
Gold has struggled to recapture $900 as speculators booked profits since pushing up prices to a lifetime high of $1,030.80 an ounce on March 17 on record high oil, which raised its appeal as a hedge against inflation, and a struggling dollar.
"Perhaps further weakness in oil will also weigh on gold. I think it will be in a range, unless we see some substantial news. The topside is $890 to $900," said Adrian Koh, an analyst at Philip Futures in Singapore.
"But on the downside, a move below $870 should bring us much lower. Perhaps we may see $845 level again," said Koh, referring to a four-month low hit in early May.
The dollar rose broadly after strong retail sales, excluding automobiles, in April supported views the Federal Reserve would probably not cut interest rates again next month. [
]Spot platinum <XPT=> fell as low as $2,030.50 an ounce, down from $2,099/2,119 late in New York on Monday, when it hit a high of $2,103 an ounce -- its best level since March 17.
"I think platinum faces strong resistance around the $2,100 to $2,120 regions. It's going to need some really bullish news to move above those regions," said Koh of Philip Futures.
Investment bank UBS <UBSN.VX> launched two ETNs offering long and short trading strategies in platinum last week. ETNs, unlike exchange-traded funds, do not purchase physical platinum to back the number of shares sold.
Palladium <XPD=> dipped to $432.50/440.50 an ounce from $436/444 in late New York. Silver <XAG=> fell to $16.68/16.74 an from $17.12/17.18 in New York.
