The cement giant put together a solid performance, rising more than 5 per cent as dealers warmed to the idea of a pounds 400m-plus disposal of the heating division. The rumours left the stock 22.25p higher at 450.75p with more than 4m shares traded.
The heating operations, which include well-know brands such as Potterton and Myson, have long been seen as a disposal candidate as it does not fit with the rest of Blue Circle's heavy building materials businesses.
But according to dealing room whispers the new chief executive, Rick Haythornthwaite, is putting the finishing touches to the sale, possibly to a foreign rival. Optimistic dealers said an announcement could come at the interims in a fortnight's time, but cooler heads said the end of the month was a more realistic target.
Some Blue Circle bears went even further and suggested that the disposal of the boilers subsidiary, which last year had profits of pounds 50m, could net even more of the expected pounds 400m.
The story was given an extra edge by talk that the company could use the proceeds to expand into Asia or even to merge with rival Hanson, up 1.5p to 530.5p.
