Exercise

Summary

Exercise is the act of using the right embedded in the option. What happens next depends on whether the contract settles by delivery, cash settlement or exercise into a futures position.

Definition

Exercise is the process by which the holder uses the contractual right created by the option. For a physically delivered equity call, exercise means buying shares at the strike; for a physically delivered put, it means selling shares at the strike. For a cash settled index option, exercise produces a cash amount based on the settlement value, strike and multiplier, while for an option on futures, exercise creates a futures position at the strike. The article also stresses that exercise is routed through brokers, clearing members and the clearing system, and that expiry processing such as exercise by exception does not remove the need to understand broker instructions and cut-off times.
