RE: AGM The best hope for the quickest information, and I believe the some Hedge Funds will do this, is to have someone at the meeting with a computer or a cellphone giving a play-by-play description of the votes.
I would not be surprised if some people use that information to try to game the Market even though there is no good evidence that the shares should move lower, depending upon who wins (for various reasons that I will not bother with at the moment).
If the warring sides do not try to discuss issues, object to rulings and procedures, and/or add items to the agenda (all of which are very possible), the Meeting could be short. On the other hand, it could easily take 3 hours or more and that would make the end of it come after the close of the Market.
As to the pssible share price change, depending upon who wins, the biggest factor will be the expectations of the shareholders concerning the implications of the voteing results, whether they are accurate or a fantasy. If enough people/funds (and there are other Pros in on this, based upon the positive reputation of the dissident, in the Hedge Fund community if not the individual shareholders on this board) think a specific result means a higher or lower price, the share price could move in the indicated direction, even if the belief turns out to be dead wrong.
My view is that who wins will make little difference to net per share, so I am not selling no matter who wins. If there is a significant price decline, it will likely be a good opportunity to add to positions, IMO.
I plan on waiting for payday or at least until a deal is announced before cashing in.
