Copper prices fell marginally by 0.02% to Rs 420.75 per kg in futures trade today, largely on a weak global trend.
At the Multi Commodity Exchange, copper for delivery in August traded marginally lower by 10 paise, or 0.02%, to Rs 420.75 per kg in a business turnover of 40,140 lots.
November copper weakened by the same margin to Rs 426.15 per kg in 2,171 lots.
Market analysts attributed the fall in copper futures to a weak global trend over concerns that demand might be weakening after Japan's industrial production unexpectedly declined.
Meanwhile, copper fell 0.3% to $7,547 a tonne on the London Metal Exchange.
