If I had invested money in Tesla, I'd take it out right now and handle the loss. This company is going to fail - all the signs are there, this sounds like a repeat of those 1999-2000 companies, complete with the scandals and fights with reporters.
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.
