TSLA is a popular gaming machine. Some like Wheel of Fortune or Blackjack or Keno, others like TSLA.
Their stock price has absolutely zero tie in to the company's balance sheet. Many folk have made millions on it, others have lost.
It will last until the stock stops fluctuating wildly. You can make quick money on a stock only if it moves up and down rapidly. And like sharks attracted to chum, the gamblers are drawn to the table.
If TSLA collapses, it has the potential to lose more play money than the GM BK cost. GM went BK during the 2009 global retreat. Cars were not selling. Many companies went BK or were sold for pennies on the dollar. Tesla doesn't currently have significant sales numbers to warrant it's purchase as a running car company, GM did obviously.
