Britain's FTSE 100 index <.FTSE> saw earlier gains evaporate and ended lower on Thursday after mining stocks including Xstrata
Miners crowded the list of FTSE 100 fallers, with Xstrata, BHP Billiton
Even Rio Tinto
There is some talk in the market about margin concerns and also there is a rumour that a Chinese minister has said something that has knocked the commodities market, said a dealer. And there's so much profit in the sector that when it is hit the move is savage.
No further information was immediately available.
The FTSE 100 share index <.FTSE> ended the session down 8.4 points at 6,081.4, falling back from an earlier five-year high at 6,113.4 points.
Aside from miners, the tone of the market remained buoyant.
Pretty much everyone has been overwhelmed by the way in which the market has steadfastly moved higher, said Mike Lenhoff, strategist at private client money manager Brewin Dolphin. But valuations are still satisfactory because the earnings are coming through.
