Why Options Lose Value Over Time (Even If Price Doesn’t Move)

Why It Matters

Understanding time decay is crucial because it can turn a correct market view into a losing trade; traders must budget sufficient time when choosing expirations or risk predictable, time-driven losses.

Summary

Options contracts lose value as they approach expiration because 'time' is a priced component—known as time decay. Using Disney options at identical strikes but different expirations, the video shows longer-dated options command higher premiums even when the stock price is unchanged. As expiration nears, the rate of decay accelerates, meaning an option can fall in value even if the underlying doesn't move. Traders must therefore consider whether the underlying will move enough and fast enough before time runs out.

We break down complex strategies into simple, repeatable systems.

Most people think options are just about being right on direction.

But there’s something working against you the entire time: the clock.

In this lesson of Options in Plain English, we break down time & expiration in plain English—so you understand why options lose value as the deadline gets closer, and how to stop getting surprised by time decay.

In plain English

Every option has an expiration date (a deadline).

And as you get closer to that deadline, the option starts losing value.

That’s time decay.

Rule:

More time = more value

Less time = less value

Think of it like an ice cube: it melts slowly at first… then faster and faster as time runs out.
