Tesla (TSLA) is the midst of its worst week, for both its stock price, and reputation, yet founder Elon Musk seems to think it’s a laughing matter, as he sent a series of April Fools’ tweets joking about the company filing for bankruptcy. Needless to say, investors concerned about the health of Tesla stock are unlikely to have been reassured by this.

The tweets culminated with an image of him passed out against a Model 3.

The callousness of Musk’s tweets is likely to exacerbate his company’s problems. I doubt the shareholders that have watched Tesla stock drop over $100 or some 28% in the three weeks are happy. And I also doubt owners who have experienced repeated mechanical problems from bad software to leaking sunroofs are laughing.

Nor are those 123,000 owners of the Model S which were recalled for faulty steering. Maybe Musk also thought it was funny to issue the recall on Friday, when the market was closed for a three-day weekend.

I know the family of the man who died in from an accident while his Tesla was engaged in autopilot isn’t in a joking mood.

Still, through all this, Tesla stock is still up some 500 percent from its 2013 levels, and sports a market cap near $50 billion. That’s larger than two of the Big 3 U.S. automakers, despite Tesla’s paltry production numbers.
