Option Premium & Theta Decay

Definition

An option's price = intrinsic value + time value. Time value melts every day — that melting is theta.

Psychology

Every day that passes, an option loses a little value — even if the stock doesn't move. That's why 'waiting' costs buyers money.

Real-life analogy

💡 An option is an ice cream on a hot day: even if nothing else changes, it melts. Near expiry it melts fastest.

Key takeaways

  • Time value → 0 at expiry; only intrinsic remains.
  • Decay accelerates near expiry.
  • Try the Theta calculator in Tools to see it in numbers.

Memory tip

🧠 Options are melting ice cream — buyers race the sun. ☀️🍦
