THE OUTCOME
How should a vertical spread be evaluated?
Evaluate a vertical spread from payoff limits through execution and expiration: two legs create one position, width sets the frame, defined risk is not trivial, and expiration adds discontinuity.
Use this guide to: Compare debit and credit vertical spreads by payoff, maximum loss, liquidity and assignment risk.
CORE MODEL
What are the four core ideas to know before acting?
Four ideas anchor the guide: two legs create one position, width sets the frame, defined risk is not trivial, and expiration adds discontinuity.
Width sets the frame
Strike distance and net debit or credit determine simplified maximum gain and loss.
Defined is not trivial
A known maximum loss can still be too large, and assignment can complicate the path.
Expiration adds discontinuity
Pin risk, exercise and settlement can make the last hours materially different.
ACTION CHECKLIST
What are the six steps of the review process?
The six steps run from calculating max gain and loss in dollars through using a single multi-leg order, checking spread liquidity on both legs, defining profit, loss and time exits, reviewing assignment buying power, and closing positions that should not reach expiration.
- Calculate max gain and loss in dollars
- Use a single multi-leg order
- Check spread liquidity on both legs
- Define profit, loss and time exits
- Review assignment buying power
- Close positions that should not reach expiration
PRIMARY SOURCES
Which primary sources should you verify?
The moving parts are the OCC’s Characteristics and Risks of Standardized Options, the Cboe Options Institute and FINRA’s options material — current official material controls, since defined risk still permits loss of the full amount at risk.
