Diversified mining group Anglo American gained despite saying it will recognise a 4.0bn dollar impairment charge in its 2012 results after completing a detailed cost and schedule review of its Minas-Rio iron ore project in Brazil. The gain appeared to be part of a wider trend, with sector peers Evraz, Rio tinto, Antofagasta and BHP Billiton were all making strong gains. Energy group SSE was seen rising one day after Credit Suisse kept its 'outperform' recommendation for the shares, saying that value-creation is expected to continue. Ahead of the company's third-quarter trading update on January 31st, the broker said it expects a 6.2% growth in full-year profits, compared with the company-supplied consensus estimate for a 5.5% increase. Anglo-Dutch oil mammoth Shell was also higher following reports that it could be close to buying the liquefied natural gas (LNG) business of Spanish company Repsol. While shares in Royal Bank of Scotland were being hammered on Tuesday by concerns about alleged LIBOR manipulation in the US, the stock was being weighed down further by a downgrade by Espirito Santo. Lloyds was also taken down a peg by the broker in its review of the UK banking sector. BT Group dropped after Bank of America cut its target price on the stock from 285p to 265p, downgrading it to neutral from buy.
