tjt2307 said "This guy (HG) has written a damning article about ALGN (see 4:53 link to CBS Marketwatch on Yahoo). Is he to be believed?" No. Greenberg is the mouthpiece for Rocker Partners, an infamous SHORT investment company. A typical Greenberg bash article always quotes an unnamed short giving dubvious reasons why he is short. Dave Rocker lost his ass last year, down something like 70%, but is making a comeback thanks to Greenburg, offshore accounts, and many unethical, if not illegal, stategies.

Mr. Herb Greenberg, I have never seen a negative guy like him. Mr. Herb Greenberg has been very pessimistic about the company since two years ago. It means when the stock was traded about $1. Do you not think this is convincing? If you follow up with the company you will right away refuse his pessimistic report about the company. And please the company can not satisfy every one on the face of the earth even Mr.Herb Greenberg. Please read carefully and make sure you understand financials of the company before taking any bad decision.
