13 December sell of 12,993,809 shares exactly matched the holding of Aggregate Industries. The other "sells" approximately equal this amount and are therefore likely to have been buys.
Expecting RNS soon saying Aggregate have sold out but who has bought?
The last two days have seen a bit of selling (nervous holders?), but, when we know who has bought the shares, I expect things to settle down again. Current share price is not far above the 2005 support level and, now the big Aggregagte sell has been mopped up, we may see the SP rise again.
