Well, I guess its obvious... most folks, especially those on board in the last 60 days don't understand or give a rat about windfall, so this type of halt will take a swipe at the share price.
I don't think Mr. Nemis is in this alone. I remember him saying in reponse to this question about the logic going of halts going forward, that he and the exchange had come to an agreement where he would share this kind of news with them and together they would decide whether a halt was justified.
I'm glad he did halt. Windfall is worthy of the respect, but for the day traders I imagine is messes with their plans a bit.
