Definition

Your share basis after assignment credits, return of capital, and other basis-affecting events.

  • Translate the term into position sizing and trade management, not just vocabulary.
  • Ask how the term changes your entry, adjustment, or exit.

Why it matters in the wheel

It tells you the real break-even on shares held through the wheel.

  • A useful definition should change what you track each week.
  • If the term does not affect capital, assignment, or premium quality, it is usually secondary.

Common mistake

Subtracting every option premium from share basis even when it should stay in option P/L.

  • Most wheel errors come from skipping the denominator behind the term.
  • Write the term in plain language inside your trade notes before you use it.
