Vertical Spread
A vertical spread buys one option and sells another at a different strike, both in the same expiration. Learn the four types and how each one profits.
A vertical spread buys one option and sells another at a different strike price, both expiring on the same day. It is the most common spread there is, and the building block for a huge share of real options strategies.
The name sounds technical, but it just describes the picture: two strikes stacked vertically on the same expiration. Let me unpack it and show you the four flavors.
Why "Vertical"
On an options screen, strikes are listed in a column, stacked top to bottom by price. When you buy one strike and sell another in that same column, same expiration, your two legs sit vertically above and below each other. Hence "vertical."
The shared expiration is the key detail. Both options live and die on the same date, so the trade is a clean bet on where the stock lands by that day. You are not juggling different time frames, just two strikes on one deadline.
The Four Types
Verticals come in four flavors, built from calls or puts, leaning bullish or bearish. Two are debit spreads (you pay to enter, betting on a move) and two are credit spreads (you collect to enter, betting a level holds).
Bull call spread (debit). Buy a lower call, sell a higher call. You pay to enter and profit if the stock rises toward the higher strike. This was the Apple example in the spread lesson.
Bear put spread (debit). Buy a higher put, sell a lower put. You pay to enter and profit if the stock falls toward the lower strike.
Bull put spread (credit). Sell a higher put, buy a lower put. You collect premium and keep it if the stock stays above the higher strike.
Bear call spread (credit). Sell a lower call, buy a higher call. You collect premium and keep it if the stock stays below the lower strike.
What They All Share
No matter which of the four you pick, every vertical spread gives you the same two gifts.
Defined max loss. You always know the most you can lose before you enter. For a debit spread it is what you paid. For a credit spread it is the width between strikes minus the credit you collected.
Defined max profit. The most you can make is fixed too. For a debit spread it is the width minus what you paid. For a credit spread it is the credit itself.
That fully boxed-in shape, known worst case and known best case, is why verticals are the go-to structure for traders who want to express a view without open-ended risk.
- A vertical spread buys and sells two strikes in the same expiration.
- It comes in four types: bull call, bear put, bull put, bear call.
- Debit spreads you pay for; credit spreads you collect.
- All four have a defined max loss and max profit.

Three quick questions to see what stuck. Pick an answer and the explanation shows up right away.
What makes a spread "vertical"?
Vertical means two strikes stacked in the same expiration column, one bought and one sold.
Which type do you collect premium to enter?
Credit spreads, such as the bull put and bear call, bring in premium up front. Debit spreads cost money.
What do all four vertical spreads have in common?
Every vertical is fully boxed in: both the worst case and the best case are known before you enter.
Bottom Line
A vertical spread is two strikes on one expiration, one bought and one sold. It comes in four flavors, debit or credit, bullish or bearish, but they all share the same clean shape: a known max loss and a known max profit.
That defined risk is why the vertical is the everyday tool of serious options traders. Pick the flavor that matches your view, and you have a tidy, boxed-in bet with no ugly surprises.
