Shorts do add liquidity. It’ll be an interesting market without them. You’d be crazy to short in this nonsense.
Shorts have a purpose. They dug through companies filings and do due diligence and uncover shenanigans like Enron. Naked shorting is supposedly illegal but how does one account for 100+% shorting? But they have been a destructive force against some small businesses that can’t raise capital after severe stock price decline (even if not deserved). So there’s plusses and minusses.
I wouldn’t short but I did worse, I bought gold.
