I get there alerts normaly but nothing on this one.
I think they have broken their followers into groups. Alerts come in sequences so can keep a momentum going and so certain group can make a profit from time to time. Otherwize, no one would follow them.
Im not sure PCS has been doing what they are the past week or two, but I would stay away from it. The 70 % gain before they announced it was probably them securing a position, now they will sell into the buying slowly until they are out - it will drop and everyone will panic and it will be right back where it started or close to it. They have had some good ones in the past and followed a different pattern, Im not sure why they would do things this way.
