Amid profit-booking by speculators and a weak trend overseas, copper prices declined by 0.66% to Rs 447.50 per kg in futures trade today.
At Multi Commodity Exchange, copper for delivery in February fell by Rs 2.95, or 0.66%, to Rs 447.40 per kg, with a business turnover of 803 lots.
November copper traded lower by Rs 2.85, or 0.64%, to Rs 442.55 per kg, with a business turnover of 7,213 lots.
Marketmen said besides profit-booking by speculators, a weak trend in overseas markets due to a firm dollar and concerns over Europe's debt crisis, led to the fall in copper prices at futures trade.
Meanwhile, copper for three-month delivery slipped as much as 0.50% to $8,238 a tonne on the London Metal Exchange, reversing an advance in the previous session.
At Shanghai, the metal for most-active January contract dropped 1.1% to 59,090 yuan ($9,400) per tonne.
