NEW YORK/LONDON, Aug 28 (Reuters) - Gold hit a three-week high above $960 an ounce Friday on the back of strong investment demand and buying linked to the initial dollar weakness, but lackluster U.S. consumer sentiment data prompted profit-taking in the metal.
The price of gold has been largely confined to a trading range between $930 and $960 in the past three months, as the metal was pressured by a resurgent dollar but supported by long-term inflation worries and lingering economic uncertainties.
"The precious metals rallied on playing catch-up to the dollar weakness from yesterday afternoon, as well as bullish technical signals," said Miguel Perez-Santalla, vice president of sales at Heraeus Precious Metals Management in New York.
Gold futures, however, retreated from session highs as a mixed bag of economic indicators, including a drop in U.S. consumer sentiment, prompted the dollar to turn higher against the euro late in the session.
The dollar typically moves in the opposite direction to the metal.
U.S. December gold <GCZ9> rose to a session high of $964.60, its loftiest price since Aug. 7. It settled up $11.50, or 1.2 percent, at $958.80 an ounce on the COMEX division of the New York Mercantile Exchange.
Spot gold <XAU=> at $956.40 an ounce at 2:06 p.m. EDT (1806 GMT), against $946.75 an ounce late in New York on Thursday.
Perez-Santalla said bullion holdings in gold exchange-traded funds rose to a recent high on Thursday, and selling of physical gold has also slowed down.
Holdings of Julius Baer's <BAER.VX> gold-backed exchange-traded fund rose 43,600 ounces, or 2 percent, in the week to Aug. 26. [
]Saxo Bank senior manager Ole Hansen said that, in the near term, the dollar will still predominantly be the currency that is in the driving seat.
"That has managed to tip (gold) through a technical level where new buying and short-covering has been triggered this morning, and that has given us a bit of momentum on the upside," Hansen said.
SILVER RISES
Silver was also helped by gains in base metals, with copper up more than 4 percent. Silver, also used as an industrial metal, was last at $14.76 an ounce from $14.24. [
]Platinum was supported by a strike at South Africa's Impala Platinum <IMPJ.J> and news that a union had rejected the latest wage offer from Anglo Platinum <AMSJ.J>, the world's largest producer of the metal. [
]Platinum <XPT=> was at $1,243 an ounce against $1,240.50, and palladium <XPD=> was at $285.50 against $284. South Africa is the source of four-fifths of the world's platinum.
The National Union of Mineworkers said Implats, the world's No. 2 platinum producer, had failed to secure a court order to stop the strike. Some workers at its Rustenburg mine have been on strike since Wednesday.
But a rise in platinum stocks after demand fell for the autocatalyst material, news of capacity cuts from Toyota earlier this week, and hopes industrial action will be resolved quickly are limiting gains, analysts said. [
]"The market reaction to these supply interruptions help confirm our view that this is not an attractive tactical entry point into new long platinum positions," said UBS analyst John Reade in a note.
