Just taking a shot in the dark... but I wonder if this strange pattern illustrates how a prearranged trade might take place.
i.e., given a stock that has had no activity for a long period, wait until an established time when the "buyer" places an ultra low bid for shares that is surprisingly filled by the prearranged "seller."
If so, this might represent a quick and inexpensive way to transfer a large block of shares from a European owner to an American owner.
A test of whether this may of happened might be to see if any more shares are transferred on Monday.
