What a complete clown. No wonder he got zero traction at any investment firm. he goes about 1 inch deep and draws conclusions. I have no doubt that he had "a few failures ". I did wonder if he was trying to put out something negative to try to keep the price down, but he really doesn't seem clever enough for that.
I still have a little cash - and I have an appetite for more PTK because I have gone more than 1" deep. I like what I see and I have been a very successful institutional investor for 20 years with major mutual funds and pensions.
