Motley Fool's Mike King on CLH, page-11

I dunno about that. They have made some pretty good picks on dividend trader (Bellamy's etc). Sure CLH was a dud initially but followed the advice and got in around 1.90 -- then tripled my position rather than following the sell advice in high 90s and low 1s as it looked like a total market overreaction. PRG is another good example.

It is caveat emptor after all. You can't blame them for every bad pick they make. No one is 100%.
