Short-sellers have been looking for weeks to pounce on Tesla, and CEO Elon Musk's incendiary call with analysts Wednesday could just provide more for them to feast on.
Bets against the electric car maker have zoomed 41 percent since March 6, according to S3 Analytics, which tracks short interest. That amounts to just shy of $11 billion in short interest, more than double that of Facebook.
With shares dropping more than 7 percent at one point Thursday, the flock of traders expecting Tesla to keep falling had reason to feel edified. In all, Tesla shares have slid more than 16 percent since the surge in short-selling, including Thursday's damage.
