I guess market manipulation must be legal, for example remember that guy who shorted Herbalife then tried to manipulate its price downward?

Whatever made that legal must make what you propose legal too: after all she could say "I shorted the stock because I thought it was doomed; I shared my frustration on Twitter out of the same frustration."

That's quite hard to separate from "I shorted the stock because I knew that I could manipulate it into falling by tweeting a negative opinion about it."

It's funny, no one thinks it's a problem to buy a stock and then go tell people good, truthful about the company to try to get the stock to go up. But when you short a stock and then go say bad, truthful things about the company then people want to call it market manipulation.

What's to laugh at. In the first case you are financially vested in something's success. In the latter case you are invested in something's failure.

There is a difference between insuring a house you want to live in and insuring a house you want to burn down.

Bill Ackerman. Though in all fairness I think he was pointing out some accurate aspects of Herbalife's organization.
