After one of our recent PowerOptions webinars an attendee asked:
“What happens if you have a vertical call or put credit spread that expires In the money?”
If both options of a credit spread (Bear Call Credit or Bull Put Credit) are in the money at expiration you will receive the full loss on the spread. You will be obligated to deliver shares of stock or buy stock at the short option strike price, and your broker would use the long option to cover the obligation.
