I think they will come back by saying you should have called to see what the current rate is for the "hard to borrow" stock...Before trying an option with such a risky move. They may even say the words "hard to borrow" would be indicative of how risky this move is!! You presented yourself as an expert, did you not?? They would ask you if you knew what an "uncovered position" means. Do you understand margins and float on accounts? If you say no, they would say you lied on your option form!! If you had made $100,000. from this account there wouldn't be a problem. Just saying...
