Ratio Calendars, and the Call That Looks Free

Advanced · 13:17

Sell two one-month calls against one three-month call, and you pay almost nothing. This lesson shows why that small debit doesn't limit the loss, and what the leftover call really cost.

After this lesson you can

  • Break a ratio calendar into a calendar spread plus a naked call
  • Find where it peaks and where the cliff starts on the day the short calls expire
  • Explain why an early rise hurts more than the same rise at the end
  • Decide what to do with the call you still hold after the short calls expire
  • Avoid the five mistakes, above all treating the $36 debit as the most you can lose
