"Remember, when you see "National Bank" it is not necessarily the bank itself that is selling the stocks.  It is merely an indication that the National Bank was the broker that was used for the sale of the stocks.  It may not be the same client that was selling either. "

Indeed that is the case and one would surmise that from the showings on level two. Curious, however, that such a string of sales would come from the same entity.  I've been watching level II for some time and a string of sales like that tends to catch the attention, particularly when they are sales at a low on a company with very promising news to come.  One doesn't have to think to far to see a move like that as a scare tactic, which it quite likely was.
