What has changed in the few weeks Tesla has been a public company? Doesn't seem to be any underlying change that would have shifted the company towards failure unless that was already the path. So either the shares aren't worth what they were listed at and investors made a bad call or it could be people getting out purely because the share price is heading in the wrong direction right now.
