Taking negative cues from the global markets and subdued domestic demand, copper prices extended losses for the second straight day by falling 0.34% to Rs 437.95 per kg in futures trading today.
At the Multi Commodity Exchange, February copper declined by Rs 1.50, or 0.34% to Rs 437.95 per kg in business turnover of 7313 lots.
The April contract shed Rs 1.45, or 0.33% to Rs 442.45 per kg in 415 lots.
Market analysts attributed the fall in copper futures to weak global trend amid concerns that budget negotiations deteriorated in the US.
