Copper prices fell by 0.4% to Rs 434.50 per kg in futures trade today after speculators trimmed positions, tracking a weak global trend on China growth concern.
At the Multi Commodity Exchange, copper for delivery in far-month November fell by Rs 1.65, or 0.38%, to Rs 434.50 per kg in business turnover of 418 lots.
In a similar fashion, the metal for delivery in August declined by Rs 1.55, or 0.36%, to Rs 426.65 per kg in 4,078 lots.
