What would the broker do about this naked call option?
The broker would give you a margin call and get you to deposit more funds into your account. They wouldn't wait for the stock price to reach $30, but would take this action much earlier. More over it is very unrealistic for any stock to go up 275% over a few hours, and if the stock was this volatile the broker would be asking for a higher margin to start with. What I am really worried about is that if there were any situation like this you are not considering what you would do as part of your risk management strategy. Before writing the option you should already have an exit point at which you would buy back the option to limit your losses.
