If the mm's dont have any stock to borrow i.e our shares then shorters will have to give up the borrowed stock and pay a premium.
Therefore if everyone on here sets a sell limit and it stops them from borrowing our shares they are going to get stung.
when you short sell a stock, your broker will lend it to you. The stock will come from the brokerage's own inventory, from another one of the firm's customers, or from another brokerage firm. The shares are sold and the proceeds are credited to your account. Sooner or later, you must "close" the short by buying back the same number of shares (called covering) and returning them to your broker. If the price drops, you can buy back the stock at the lower price and make a profit on the difference. If the price of the stock rises, you have to buy it back at the higher price, and you lose money.
Most of the time, you can hold a short for as long as you want, although interest is charged on margin accounts, so keeping a short sale open for a long time will cost more However, you can be forced to cover if the lender wants the stock you borrowed back. Brokerages can't sell what they don't have, so yours will either have to come up with new shares to borrow, or you'll have to cover. This is known as being called away. It doesn't happen often, but is possible if many investors are short selling a particular security
