Mumbai: India's benchmark stock index advanced. Sterlite Industries (India) Ltd. led metal producers higher after copper gained for a second day.

Sterlite, the nation's largest copper producer, rose 1.7 per cent as the price of the commodity increased on speculation that demand may reduce stockpiles. Tata Steel Ltd., the biggest producer of the alloy, added 1.6 per cent.

"Commodity prices have been beaten down so we are seeing a rally in prices as some data points improve and that's boosting stocks," said Vaibhav Sanghavi, a director at Ambit Capital Ltd. in Mumbai, who manages funds for wealthy individuals.
