The trouble is no one told the mining companies, which all traded higher. It has raised Rio Tinto, up 24p at 1403p, from sell to hold while cutting BHP Billiton, 2 1/4p firmer at 441 1/2p, from hold to reduce and Anglo American, up 13p at 1225p, from reduce to sell. It is telling clients to switch out of Anglo American and into Rio Tinto, but keeps an underweight rating on the sector.
