Mining stocks helped recouped yesterday's losses after Goldman Sachs ramped up price targets across the sector in expectation of a China-fuelled rally in commodity prices."Datapoints from China, and a more bullish outlook from our colleagues in the region, prompt us to analyse which metals might soonest experience capacity constraints," the broker said. "We believe that GDP growth close to, or slightly above our economists' current forecasts, could result in copper and iron ore suffering capacity constraints by 2011."The broker more than triples its target price on Vedanta to 1,997p from 537p.
