Copper futures prices fell by 0.71% to Rs 420.10 per kg today as speculators booked profits after yesterday's gain.
A weakening trend at the London Metal Exchange also kept pressure on the copper futures prices here.
At the Multi Commodity Exchange, copper for delivery in June eased by Rs 3.05, or 0.71% to Rs 420.10 per kg, with a business volume of 2,252 lots.
It had ended 1.47% higher at Rs 423.150 per kg in the previous session. Similarly, the metal for delivery in August shed Rs 3, or 0.70% to Rs 425.60 per kg, with a trade volume of 148 lots.
Market analysts said offloading by speculators to book profits amid a weak trend at the London Metal Exchange on stronger dollar, mainly led to the decline in copper futures prices here.
Meanwhile, copper for three-month delivery was trading 1.01% lower at $9,247.50 a tonne in early trade today at the London Metal Exchange pressured by a stronger dollar overseas.
