I hate to say it, but Mark Spiegel called Elon's bluff when the stock was at $380 and increased his short position.
The man has balls of steel for making that move. And he's on the winning side now
Although I would never short TSLA, I backed up his argument (that there was not going to be a "above $420 short squeeze", and thus his maximum losses were practically capped), and took no shortage of hatred here for doing so :Þ
The only thing that kept me from selling at $380 (I certainly wasn't buying!) was uncertainty about how long I'd have to get back in. By the time that uncertainty was cleared up, the price had fallen so much that I no longer had an interest in selling.
