Wow, that's an extensive list. Citron, definitely an edge if you are able to interpret the scope of their research news quickly. Nio was a perfect short, when they negatively mentioned it.
Its not that easy to be honest. They are usually hard to borrow and not optionable for puts. 100% runners, I've seen some 1000% runners to. Follow through days also. They do all come down eventually, but they can take time. Look at NIO, NIO is a 5 dollar stock. Imagine shorting that at 10 dollar, you'd be in deep shit.
Agree 100%. In hindsight it always seems easy... But you don't know where it will top. Also look at KODK squeeze, this things can go up longer than you are willing to risk or even stay solvent... If short, then you are imo better off shorting when it already came back down significant and with a stop at previous high. But shorts are not or almost not available. And if so they are extremely expensive, i've seen location fees of well more than 10% of stock price.
