Intrinsic and extrinsic option value

How an option’s premium splits into intrinsic value and extrinsic value, and why an out-of-the-money call can still change price before it expires.

Key terms

Intrinsic value
What an option is worth if it expires immediately. Stock minus strike for a call, and never below zero.
Extrinsic value
Premium minus intrinsic value. The part you pay for time and for how large a move might be.
Moneyness
In, at, or out of the money: whether the strike is already on the right side of the stock.
