"In the 4th situation, which was approx 30 million shares, I think we are seeing selling pressure from those shares. This is a lesson learned and we would be very cautious about doing business with that firm again based on this experience."
and you ignored another possiblity.....delay of MA projects?
here's your chart. There is no volume to indicate buying/selling....but much to indicate selling and it occurs right after the expectation that MA projects would be delivered by the end of December from my perception
