Leading the way north was Experian, the credit reference and anti-fraud company, after it hiked its interim dividend by 14% after a strong financial performance in the first half of its financial year. Revenues of $2.3bn were up 15% on 2010's figure of $2.0bn. On a constant exchange rates (CER) basis, revenue was up 11% year-on-year, though some of this was achieved through acquisitions; organic revenue growth came in at 6%.Prime Markets did its bit to boost the firm's share price, saying it expects Experian to retest the current 52-week high, saying that the group is "very much at the forefront of the global credit service boom". Acquisitive insurance group Resolution continued to perform well one day after it said its Friends Life Group subsidiary has entered into a 'transformational' outsourcing arrangement with Diligenta, an insurance services specialist that is part of Indian information technology (IT) contractor Tata Consultancy Services. Kazakhstan-focused miner, Eurasian Natural Resources was rising despite reporting that its revenue in the first nine months of the year had increased significantly driven by higher prices for its main commodities and increased sales volumes.The firm spooked investors by saying its financial performance had been hit by higher prices for raw materials, pushing shares down 2% in early trading. Shares were up over 2% in the afternoon though.Also rising was mining colossus Anglo-American after it sold off a large minority stake in its Chilean copper business for a reported $5.39bn to Japanese trading house Mitsubishi Corporation.Meanwhile Vedanta's shares took a bashing, falling 70p to 1,180p in early trading in an admittedly weak mining sector, after the firm reported its half-year earnings per share took a dive. However, the company did unveil year-on-year increases in both revenue and profit for the half year ended 30 September on the back of production growth in zinc, silver, copper, aluminium and power.
