It is time to start openly discussing a taboo subject here on this fans forum: what would happen if Tesla goes broke under a massive burden of debt and unfulfilled promises?
Elon Musk himself joked about it in his April 1st tweet, which may have been a nervous twitch. If so I don't blame him for being twitchy, because sensible investors are also starting to wonder if this is just another hi-tech bubble.
The facts are stark: he is now counting the cost of paperclips and toilet paper: "I have asked the Tesla finance team to comb through every expense worldwide, no matter how small," he wrote.
Last week, Musk revealed that he was "under stress" and the firm was going through a period of "production hell". He told CBS news he sometimes resorted to sleeping on the office couch at the car plant.
Analysts say Tesla's problems are serious.
Since September, the firm's shares have fallen by about a quarter to $296 - and many investors think they will continue to drop.
As of April 25, Tesla was the most shorted company in the US, according to S3 Partners, a financial data and analytics firm.
John Thompson, chief executive of Vilas Capital Management, is one of the people who has put money on the idea that the share price will collapse, placing pressure on the company and eventually leading to bankruptcy.
"Over the next three to six months, I've said I think the stock will fall significantly, at which time the capital markets will close to Tesla entirely," he said. "Then it's just a matter of time given their losses and their capital expenditure needs."
If I were a vulture capitalist (which I ain't) I would also be shorting Tesla stock right now, not because I want them to fail, but simply because they are.
