I agree about it looking like one buyer broken up. Seems like someone feels the bottom has been reached and considering the fact that PTSC likes to announce news after the bell on Fridays, the purchase of approximately 100K shares is in anticipation of that.
I personally don't think the bottom has been reached and the purchaser will be disappointed with the continued gradual decrease in PPS. He/she is already trapped in their purchase by the wide bid/ask of nearly 5%.
GLTA, but I think we have some more downward to endure.
