ELON MUSK WARNS: A 'Tsunami Of Hurt' Is Coming For Anyone Betting Against Tesla

But there's also no question that Tesla has come much farther than many have expected.

Earlier this year, the company managed to deliver its first and second net profits (adjusted for items) ever.

Still, the short interest on the stock is about as high as it goes.

"I think it's very unwise to be shorting Tesla," warned Musk in an interview with Fox Business News' Liz Claman. "There's a tsunami of hurt for those holding a short position. It's going to be very unpleasant. I advise people to exit while there is still time."
