I just had a look at the closing trades,(not level 2) and I'm inclined not to worry. OK there was an unusually sizeable dump that lowered the bid to 15.5, but following that there were some buys in quantities that are normally significant in the present trading climate on this stock. Enough to rally the closing price back to 16, and I'm heartened by that. Even with the large trade, only about a half of a percent of the outstanding shares changed hands today, and the dump was just over one eighth of a per cent.
We can't assume that they were dumped by someone who knows something we don't. Don't forget that two of the partners were involved in an exhibition today. I'm sure that some regular poster on one of the bulletin boards would have been there, watching the faces of the members of the BOD or their representatives like hawks for some sign one way or the other. I think there has never been a tighter hole in Newfoundland than this one, and the BOD must be wearing poker faces. I don't think anyone is getting privileged information. And if this represented a panic dump by the drill crew, wouldn't that have been spread across a number of investment houses? One person or one organisation with a lot of shares needed some money. That's my guess.
