Tinroad: Perhaps my explanation was not clear. The owners of the both CP shares want to sell (short) at a high PPS and convert (cover) at a low PPS. Therefore some hire promoters to pump while they are selling.
What I was trying to explain is that the Series E CP holders make more money the lower the PPS is at conversion (down to 0.19), whereas the Series D CP holders have a current conversion price of 0.19 no matter what the PPS is when they convert.
Please let me know my explanation is still confusing.
