Extrinsic value consists of time premium and implied volatility. It approaches zero at expiration. Formula: Option Price = Intrinsic + Extrinsic. Monitor theta decay for optimal timing.
Extrinsic value is just the premium you pay for time and volatility. The market’s betting on how much an option could move before it expires.
For trading, watch how fast that premium decays. I stick with 30-45 days to expiration - gives you time for moves without paying insane premiums.
Patrick Boyle explains the math really well:
Here’s the thing - extrinsic value isn’t just wishful thinking. It’s calculated risk based on how much the stock actually moves. That’s why volatile stocks have expensive options even when they’re out of the money.
