This tweet violates so many securities laws in the US and Europe...
I get that it's a joke but not everyone understands the concept of April Fool's Day, and in the case of these tweets, there is no indication that the tweets, by a CEO of a publicly traded company with known financial issues, is not a factual statement. The Easter Egg sale would match actual past activities (like the "flamethrower" sale a few months ago) and the last, Trumpian statement would likely only be understood by those familiar with Trumpisms. The fact that he says several tweets later that they are not forward looking statements does not change the contents of this tweet.
Maybe instead of tweeting stupid jokes he should spend more time not running Tesla into the ground? Because on Tesla's current track, this joke's going to be a reality by the end of the year.
