LMAO! So the price going up 2% they are going to get a margin call - you are clueless about how shorting works.
Those shorting Mullen started after the May reverse split - the shorters make a fortune from $400 down to around $1 - they are shorting at these prices and no one is getting a margin call because of the $2.50 rule which means that for every share you short below $2.50 - you have to have $2.50 in your margin account.
So Mullen is at $0.15 and you borrow 1 million shares to short - you will be required to have $2.5M in your margin account. So you wouldn't get a margin call until the price was above $2.50.
So much for the nonsense about a margin call because the price is up 2%.
Plus, there is so much more about shorting that you obviously don't understand.
