SINGAPORE, June 19 - Shanghai copper fell almost 1.5 percent on Tuesday as investors cashed in positions after London futures failed to sustain a rally above $7,600 a tonne in the previous session.
The most-active September copper contract on the Shanghai Futures Exchange fell to 64,450 yuan ($8,455) a tonne at midday, from 65,400 yuan on Monday.
"The market is disappointed with the failure to maintain the rally in London and investors are adjusting their expectations," said analyst Wang Zheng at consultancy Fubao Metals.
He said a slowdown in U.S. growth and long-awaited cooling measures in China are weighing on sentiment for the metal.
Shanghai spot copper fell to between 63,200 and 63,300 yuan, down 275 yuan.
Copper for delivery in three months on the London Metal Exchange fell $65 to $7,475 a tonne at 0346 GMT. Copper rallied 2.6 percent on Monday to touch $7,696 in electronic trading, its highest since mid-May.
"This $7,600 level was a key point and the fact we couldn't pull away from it was disappointing," Man Financial analyst Edward Meir said.
"In the longer term, we are looking for prices to hold at current levels for the rest of the year and to fall by 10 to 15 percent in 2008," he added.
STRIKE THREATS SUPPORT PRICES

Managers at the Canadian Copper Refinery in Montreal are trying to ramp up production to around 35 percent of capacity after a strike forced the owner, Anglo-Swiss company Xstrata Plc , to declare force majeure at the plant which produced around 300,000 tonnes of copper last year.
Xstrata said no meetings were planned to resolve the dispute.
