Diversified mining giant Eurasian Natural Resources Corp (ENRC) dropped into the bottom spot after being hit by a fall in commodity prices and challenging economic conditions in the first half, meaning that both revenues and profits were significantly lower than the same period in 2011. The group slashed its interim dividend by 59.4 per cent. Rio Tinto was also lower after being among the handful of stocks that went ex-dividend today, along with Anglo American, Fresnillo, Hammerson, Meggitt, Pearson, BATS, Schroders and Vedanta.Meanwhile, Standard Chartered jumped after having reached a $340m settlement with the New York Department of Financial Services (DFS) over claims its US subsidiary illegally processed payments for Iran. Investec said that while uncertainty still remains, the settlement reduces the risk of the group loosing its banking licence. StanChart was given a lift this morning by Bank of America and Oriel Securities who both upgraded their ratings on the stock to 'buy'. Insurance group Resolution was the biggest high riser after abandoning plans to split itself up and saying it would overhaul its board structure. FTSE 100 - RisersResolution Ltd.
