Payoff at Expiry

Conceptual payoff with reference spot = 100. Strikes and premiums shown are illustrative.

Payoff depends on time decay and implied volatility — a static expiry chart would be misleading here.

AI Insight

Live

Calendar Spreads thrive in low-IV environments with rising term structure. Profit pivots on the near-term short leg expiring at-the-money while the back leg retains value.

Questions

Frequently Asked

Why is the payoff chart shown differently?+

Calendar payoff at expiry depends on the value of the back-month option, which depends on IV — it's not a simple expiry payoff.

What happens at near-term expiry?+

The short leg expires; you're left with a long position in the back-month option, which you may close or manage.
