Okay, that's all any of us can do. While not claiming I can fix PPS overnight, I do have some insight as a behavioral psychologist and hope they will listen to my ideas.
Some of my past messages have gone unanswered as well. But today I exchanged 5 emails with Sam. He agrees that stock performance has not matched company performance, and is studying the problem personally. It was good to hear that he does care about the PPS.
