Genuine question: They can just do that ? Issue a trading halt because they don't like the direction it's going ? > “There’s a reason why they have those circuit breakers -- it’s to give people time to come back from panicked feelings,” Seems strange that the market is kinda able to be manipulated like that. I'm not saying this is a bad move, just surprised that someone can do it.
Would they also circuit break on 7% increase, in order to give people time to come back from positive feelings?
There's no downside in great news (other than the possibility of a quick reversal thereafer...)
