I'm really, really hoping that Elon actually asked a securities attorney and found out that if he is not short any Tesla shares, that he can just tweet that without repercussions.

I mostly hope this because I'd really like the option to die on Mars (by which I mean, of extreme old age in a comfortable bed in a luxuriously scenic habitat). Thus, I choose to believe that Elon's occasional manic episodes are just stress and sleep deprivation from obsessive overwork.
