Copper futures prices declined by over one per cent to Rs 435.05 a kg in futures trading on Tuesday as speculators locked in gains after yesterday’s gains, amid weak trend overseas.

At the Multi Commodity Exchange counter, copper for the delivery in February declined by Rs 4.55 or 1.06 per cent to Rs 435.05 a kg, with a business turnover of 9,409 lots. It ended 0.40 per cent higher at Rs 439.60 a kg in the previous session.

The metal for delivery in April also traded lower by Rs 4.65 or 1.05 per cent to Rs 437.80 a kg, with an open interest of 865 lots.

Meanwhile, copper futures prices fell by half a per cent at the LME in early trade on Tuesday.
