LONDON July 25 (Reuters) - Copper prices hit more than five month highs on Tuesday, boosted by signs of robust demand from top consumer China, tight supplies, a weak dollar and a break of key technical levels.
Benchmark copper on the London Metal Exchange was up 2.4 percent at $6,170 a tonne from an earlier $6,175 a tonne, its highest since Feb. 14.
"China growth is looking stronger, it's encouraging at a time when you would normally expect a lull," said Cantor Fitzgerald analyst Asa Bridle. "We have a perfect combination of decent demand and tighter supplies."
CHINA GROWTH: China's gross domestic product was up 6.9 percent in the second quarter year on year, faster than the consensus 6.8 percent and the government's 6.5 percent target.
CURRENCY: The U.S. currency fell to a 13-month low against a basket of major currencies, making dollar-denominated metals cheaper for holders of other currencies and potentially helping demand.
SUPPLY: Disruptions to copper shipments from Canada and Chile have undermined expectations for rising global copper supplies in the second half of the year.
FIBONACCI: A break of $6,030, a Fibonacci retracement level, saw funds that trade using buy and sell levels from black-box models, jump on the uptrend, traders said.
TECHNICALS: Resistance is seen at $6,200 near the February high, but traders say copper is overbought and needs to consolidate before trying to tackle higher levels.
PHYSICAL DEMAND: "Manufacturers are restocking after drawing down copper stocks," a copper trader said. "There has been a fair amount of short-covering too ... Momentum seems to be running out of steam and we've seen some producer selling."
PHILIPPINES: President Rodrigo Duterte said on Monday he wants all mineral resources extracted from the country to be processed domestically and, if possible, to stop exporting such commodities.
NICKEL: The Philippines is the world's top supplier of nickel ore, for which China is the biggest market.
NICKEL PRICES: Worries about supplies pushed benchmark nickel up to $9,930 a tonne, its highest since April 11. The price was last up 1.3 percent at $9,915 a tonne.
NICKEL TECHNICALS: Upside barrier at $10,080 the 200-day moving average. Support at $9,370, the 21-day moving average.
PRICES: Aluminium was up 0.5 percent at $1,922, zinc rose 1.7 percent to $2,835, lead added 1.8 percent to $2,300 and tin gained 0.5 percent $20,250
