SABMiller, one of the world's largest brewers, rose into the top spot after it managed to beat analysts' forecasts in the first half as its hiked its interim dividend by 12 per cent. The company reported revenue of $17,476m in the six months to the end of September, up 11% on $15,688m reported the year before, and better than the $16,940m that Charles Stanley was expecting. Mining stocks were also performing well today on the back of the Chinese manufacturing data: Vedanta, EVRAZ, ENRC, Glencore, Xstrata and Kazakhmys were among the highest risers early on. Glencore and Xstrata in particular were given a boost by the news the European Commission has cleared the merger between the two. However, the blessing for the $31bn deal comes with the caveat that Glencore must terminate an exclusive deal it has with Nyrstar, the world's largest zinc metal producer.Following a sharp fall yesterday after its first-half figures, chemicals group Johnson Matthey rebounded after Credit Suisse upgraded the stock from 'neutral' to 'outperform' and lifted its target price from 2,300p to 2,400p.

However, "we suspect this has come at a cost to margin," they added.
