Earlier quoted context omitted.
It’s important to note that Elon screwed over the “longs” (people holding TSLA stock) too, not just the shorts. Many people and funds bought more TSLA stock in the $350’s range on the assumption that of course the company could/would go private at $420/share. After all, hadn’t the CEO just said so?
I was reading r/TeslaMotors that day and a long made the astute observation that shorting the stock after Musk's announcement when it hit around $380 was the most logical thing to do, because at most you'd be out 10% if Musk were telling the truth. If I had a trading account I think I might have gone for that.
It does not take that long to open a trading account or you could have taken one of your friends help to execute this trade
