^ I don't think they are subjected to this, they do not involve such pump and dump activity that can make market manipulation.
I don't understand why people blaming others when they have failed of what they invested, because actually, they don't know of what they invested for, as they saw Tesla company was a successful company and what they did, also others do. Nevertheless, in my own opinion, this doesn't have to make sense as we know Tesla company is just a big investor, not a manipulator.
