The Citron Report's author often finds stocks that have gone up, places shorts, and then promotes the idea that these companies are scams with no fundamental value. He's made a considerable amount of money doing this.
This guy runs a blog about companies that he thinks are over-valued, and he shorts their stock. He's transparent about all of this. His readers / investors / the public know that he's likely short these stocks and that he makes a business of both using this investment strategy and blogging about it. They follow his advice at their own risk, with all of the information fully available.
There's a HUGE difference between that and getting into a position that you don't disclose, manipulating a media outlet into running coverage that appears objective but which is actually designed to do nothing but help your position, and then cashing out.
This seems a clear case of bashing .. and if so, it means the article is a compliment to AMD.
