Exercise and Assignment — Concept Explainer Video

Transcript

Two sides of one event

Exercise is the holder using the contract right. Assignment is the seller being required to meet the corresponding obligation. Selling an option does not let you choose whether to accept assignment after the contract rules trigger it.

A stock call example

For a standard one hundred share call with a fifty dollar strike, exercise means the holder buys one hundred shares for five thousand dollars. The assigned seller delivers those shares and receives five thousand dollars. The option premium is separate.

Closing is a different action

Selling an owned option to close is not exercise. Buying back a short option to close is not assignment. A closing trade transfers the option at its market price and may preserve remaining extrinsic value that exercise would give up.

Early assignment can happen

American style options can be exercised before expiration, exposing sellers to early assignment. Dividends can matter for calls. European style restricts exercise to the prescribed expiry. Cash settled contracts create cash obligations instead of delivering shares.

Know what appears afterward

Check the exact contract and your broker deadlines before expiration. Exercise or assignment may create shares or futures exposure and funding needs. Once the option becomes another position, its risk is no longer described by the option premium alone.
