How do you make 100% if BBI goes to zero? I don't foresee BBI going to zero, there would be a trading halt before that happens like what happened BNB at $0.325. I have always wondered what happens when you short a stock and it goes into an indefinitely trading halt like in the case of BNB. Don't you have to buy back the stock to close out your short position, and you can't do that if a stock is in a trading halt.
