dextroisomersim : We seem to be 'kindred spirits' on the subject of AMEC.
In addition to my previous comments plus your observations I've a view that the company may well be in a position to increase its final dividend . Doubtless the CEO has been liaising with major shareholders and will be aiming to keep them on board. If you read between the lines of the recent statement the sole aim is 'to enhance shareholder value'. Whether that is to fend off prospective bidders or to extract a higher take-out price ...holders will benefit.
As to short term weakness ...one should view this as a further opportunity to top -up. Doubtless any prospective predator will as well as major holders!
