There is definitely something strange with this current "program trading" if that is what it is. There is a common "small lot trading program" on the TSX that will have certain trading houses buying up the under 500 lot purchases to keep an orderly market, but having said that - it is usually only one or possibly two trades that will happen before the rightful bidder, which in this case is RBC, will have their bid filled. That is not happening at all in this case and it seems like some sort of manipulation but to what purpose with such small amounts I don't know? Regards Paul
