RE: brissenden's 125 000 sharesI also noticed that on September 11, 2006 - EXN was not at 1.21. It's highest price canadian that day was 1.09. Several trading days before, however the price of the stock was in the 1.21 range. Dumping such a large block on a small volume issue would push the price down and it would be doubtful that it could sell as one block at $1.21.
Anyway... the explanation is probably that the date on the transaction reflects the reported date, not the actual transaction date.
