Buoyed by a firming trend in global markets, copper futures prices rose by 0.27% to Rs 424.30 per kg today as speculators enlarged positions.
At the Multi Commodity Exchange, copper for delivery in August rose by Rs 1.15, or 0.27%, to Rs 424.30 per kg, with a business turnover of 8,486 lots.
November copper moved up by 50 paise, or 0.12%, to Rs 427.80 per kg in 5,195 lots.
Marketmen said a firming trend overseas on speculation that the US Federal Reserve Chairman may hint at more stimulus to revive economic growth, raised the demand outlook for metals, influencing copper futures prices here.
Pick up in demand at the domestic spot market supported the upside, traders said.
