[What the drop in share price reflects is e decrease in the possibility of another offer coming in and trumping Shells offer with the the threat of the looming supertax.]
My take on the share price drop is that holders are waking up to the fact that the current pathetic offer may not (and should not!) get the necessary shareholder support to pass. As it is conceivable that a NO vote and consequent fall back to below $4 might occur, holders who bought around the $4.50+ mark will be getting itchy feet.
As I've stated elsewhere, I will be voting NO for my not-so-inconsiderable shareholding (have been holding AOE since 30 cents).
