What Is a Vertical Spread? Bull and Bear Spreads Explained
Learn how vertical spreads work, including bull call spreads, bear put spreads, and credit spreads. Covers setup, max profit/loss, and when to use each type.
What is a Vertical Spread?
A vertical spread is an options strategy where you buy and sell two options of the same type (both calls or both puts) with:
- Same expiration date
- Different strike prices
The name "vertical" comes from how strike prices are listed vertically on options quote boards.
Why Trade Vertical Spreads?
Vertical spreads are popular because they offer defined risk:
- Limited downside — You always know your max loss upfront
- Lower cost — The sold option offsets the bought option's premium
- Clear profit target — Max profit is calculated before you enter
Understanding how delta, theta, and vega affect your spreads will help you pick better strikes.
Types of Vertical Spreads
There are four types of vertical spreads. Each fits a different market outlook.
1. Bull Call Spread (Debit Call Spread)
Use when: You're moderately bullish on a stock.
How it works: Buy a call at a lower strike, sell a call at a higher strike.
Example: Stock at $100
| Action | Strike | Premium |
|---|---|---|
| Buy call | $100 | −$5.00 |
| Sell call | $110 | +$2.00 |
| Net debit | $3.00 |
| Metric | Value |
|---|---|
| Max Profit | $700 |
| Max Loss | $300 |
| Breakeven | $103 |
2. Bear Put Spread (Debit Put Spread)
Use when: You're moderately bearish on a stock.
How it works: Buy a put at a higher strike, sell a put at a lower strike.
Example: Stock at $100
| Action | Strike | Premium |
|---|---|---|
| Buy put | $100 | −$5.00 |
| Sell put | $90 | +$2.00 |
| Net debit | $3.00 |
| Metric | Value |
|---|---|
| Max Profit | $700 |
| Max Loss | $300 |
| Breakeven | $97 |
3. Bull Put Spread (Credit Put Spread)
Use when: You're neutral to bullish and want to collect premium.
How it works: Sell a put at a higher strike, buy a put at a lower strike.
Example: Stock at $100
| Action | Strike | Premium |
|---|---|---|
| Sell put | $95 | +$3.00 |
| Buy put | $90 | −$1.50 |
| Net credit | $1.50 |
| Metric | Value |
|---|---|
| Max Profit | $150 |
| Max Loss | $350 |
| Breakeven | $93.50 |
4. Bear Call Spread (Credit Call Spread)
Use when: You're neutral to bearish and want to collect premium.
How it works: Sell a call at a lower strike, buy a call at a higher strike.
Example: Stock at $100
| Action | Strike | Premium |
|---|---|---|
| Sell call | $105 | +$3.00 |
| Buy call | $110 | −$1.50 |
| Net credit | $1.50 |
| Metric | Value |
|---|---|
| Max Profit | $150 |
| Max Loss | $350 |
| Breakeven | $106.50 |
Quick Reference: Which Spread to Use?
| Your View | Strategy | You Pay/Receive |
|---|---|---|
| Bullish | Bull Call | Pay debit |
| Bearish | Bear Put | Pay debit |
| Neutral-Bullish | Bull Put | Receive credit |
| Neutral-Bearish | Bear Call | Receive credit |
Tip: Use debit spreads when IV is low (options are cheap). Use credit spreads when IV is high (options are expensive).
When Spreads Have Edge
Matching Spread Type to IV Environment
| IV Rank | Debit Spreads | Credit Spreads |
|---|---|---|
| < 30% (Low) | Favorable — buying cheap options | Unfavorable — selling cheap options |
| 30-50% | Neutral | Neutral |
| > 50% (High) | Unfavorable — buying expensive options | Favorable — selling expensive options |
The Probability Reality
For credit spreads, a "70% probability of profit" means:
- Win 70% of the time (small gains)
- Lose 30% of the time (larger losses)
Long-run math:
| Outcome | Frequency | P&L Each | Total |
|---|---|---|---|
| Winners | 70 trades | +$100 | +$7,000 |
| Losers | 30 trades | −$200 | −$6,000 |
| Net | 100 trades | +$1,000 |
High win rate ≠ guaranteed profits. Position sizing and loss management determine actual returns.

Frequently Asked Questions
What is the maximum profit on a vertical spread?
For a debit spread (bull call or bear put), maximum profit equals the width of the strikes minus the net debit paid. For a credit spread (bull put or bear call), maximum profit equals the net credit received.
What is the difference between a debit spread and a credit spread?
A debit spread requires you to pay premium upfront (you buy the more expensive option), while a credit spread pays you premium upfront (you sell the more expensive option). Debit spreads profit from directional moves; credit spreads profit from time decay and the stock staying in a range.
When should I close a vertical spread?
Most traders close vertical spreads at 50-75% of maximum profit to lock in gains and reduce the risk of the trade reversing. For credit spreads, closing early also frees up buying power for new trades.
Can I lose more than my maximum loss on a vertical spread?
No. Vertical spreads have defined risk. Your maximum loss is limited to the net debit paid (for debit spreads) or the width of the strikes minus the credit received (for credit spreads).
