Copper prices fell by 0.43% to Rs 421.65 per kg in futures trade today as speculators reduced their positions largely in line with a weakening trend overseas.
Subdued demand at spot market from consuming industries also put pressure on the metal's prices at futures trade.
At the Multi Commodity Exchange, copper for delivery in April shed Rs 1.80, or 0.43%, to Rs 421.65 per kg, with a business turnover of 1,650 lots.
The February contract fell by similar margin to Rs 416.90 per kg, with a turnover of 24,554 lots.
Analysts said selling by traders in tandem with a weakening global trend amid concerns that Chinese demand may decline as prices continue to slide in the world's largest consumer of metal, mainly led to the fall in copper futures prices.
Meanwhile, copper dropped 0.8% to $8,370 a tonne on the London Metal Exchange.
