Expiration: how options run out of time

Unlike a stock, an option has a deadline. The expiration date is when the contract stops trading and is settled — and the approach to it shapes how the option behaves the whole way there.

What expiration means

At expiration, an option is worth only its intrinsic value — whatever it's actually in-the-money by — and nothing for time. An in-the-money option is typically exercised or settled; an out-of-the-money one expires worthless. Everything you paid for "time and possibility" is gone.

The road to expiration

Two things intensify as the clock runs down:

• Time decay accelerates. The "time value" portion of an option erodes faster and faster near the end (this is theta). The final days can be punishing for buyers.
• Behavior gets more extreme. Close to expiration, small moves in the underlying can swing the option's value sharply, because there's no time left to recover.

This is exactly why zero-days-to-expiration options are so volatile — they live entirely in the steepest, twitchiest part of the curve.

Why it matters for risk

Expiration turns "I'll be right eventually" into a losing strategy for option buyers. You're not just betting on direction — you're betting it happens before the deadline. Misjudge the timing and you can be right about the move and still lose everything to the clock.

Knowing your expiration, respecting the decay that comes with it, and not holding long options into their final hours by accident are basic survival skills — not advanced ones.
