Your description makes it seem more nefarious than it is.

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.

That should land you in jail.

No it shouldn't. The entire liquid stock market exists to make it possible for people to identify incorrect prices and make money by correcting them.

Market manipulation through pseudo-libel is not quite the same thing as ordinary price discovery.

Interesting, I didn't know that. Does this have a name ? a reverse insider fraud ?

Wow, there are quite a number of tricks to monitor. I don't know how they handle it in reality.

This seems a clear case of bashing .. and if so, it means the article is a compliment to AMD.
