Can't help noticing there is a deliberate ploy to keep the SP at 8.9c, been doing for the past week, every time there is a buy at 9c it is shortly followed by a sell at 8.9c and for the same volume each time (today it is 1771 shares each time). I only know of two reasons for deliberately keeping the SP low, shorting is one but unlikely in this case, the other is in preparation for a buy out.......thoughts?
