Genuine question for anyone who's tried it. If you've shorted names in these sectors and actually closed the trade for a profit - not just paper gains on an open position - how did you do it? How did you size it, how did you handle borrow and squeezes, and what made you cover? Or did puts work better than shorting shares?

Trying to figure out whether the winners had a process or just got the timing right.
