A vertical spread combines buying one option and selling another of the same type (both calls or both puts) with the same expiration but different strike prices. The name comes from the way strikes are listed vertically on an option chain. Vertical spreads cap both the maximum gain and the maximum loss, reduce the cost of buying options and reduce the risk of selling them. They are among the most practical strategies for directional trading with defined risk.

## The four vertical spreads

| Spread | Construction | Paid or received | View | Lesson |
|---|---|---|---|---|
| Bull call spread | Buy lower call, sell higher call | Debit | Bullish | [Bull Call Spread](https://learn.tradelabsai.com/options/bull-call-spread/) |
| Bear put spread | Buy higher put, sell lower put | Debit | Bearish | [Bear Put Spread](https://learn.tradelabsai.com/options/bear-put-spread/) |
| Bull put spread | Sell higher put, buy lower put | Credit | Bullish | [Bull Put Spread](https://learn.tradelabsai.com/options/bull-put-spread/) |

## Debit vs credit spreads

- **Debit spreads** cost money to open. You buy the more valuable option and sell a cheaper one. You profit if the underlying moves in your direction. Time decay generally hurts until the spread is in the money.
- **Credit spreads** pay you to open. You sell the more valuable option and buy a cheaper one for protection. You profit if the underlying stays on the right side of your short strike. Time decay generally helps.

```
debit spread: max loss = debit paid, max gain = width - debit
credit spread: max gain = credit received, max loss = width - credit
```

## Same view, two ways

A bull call spread and a bull put spread at the same strikes have nearly identical payoffs, as put call parity implies. The choice between them comes down to price, liquidity, early assignment risk and whether you prefer to pay up front or receive a credit.

**Example: Bullish on a $100 stock, two structures**
Strikes $100 and $105, 30 days to expiry.

- **Bull call spread:** buy the $100 call for $3.20, sell the $105 call for $1.10. Debit $2.10. Max gain $2.90 at $105 or above. Max loss $2.10 at $100 or below. Break even $102.10.
- **Bull put spread:** sell the $105 put for $5.95, buy the $100 put for $3.00. Credit $2.95. Max gain $2.95 at $105 or above. Max loss $2.05 at $100 or below. Break even $102.05.

The payoffs differ by a few cents because of interest and pricing differences. Per contract, multiply by 100.

## Choosing strikes and width

| Choice | Effect |
|---|---|
| Wider strikes | More profit potential and more risk; behaves more like a single option |
| Narrower strikes | Less of each; cheaper and lower risk |
| Strikes closer to the money | Higher probability, lower reward to risk |
| Strikes further out of the money | Lower probability, higher reward to risk |

The ratio of maximum gain to maximum loss reflects the market's view of probability. A spread that risks $1 to make $4 is unlikely to reach maximum profit; one that risks $4 to make $1 is likely to profit but loses more when wrong. See [Risk/Reward Ratio](https://learn.tradelabsai.com/risk/risk-reward-ratio/).

## Greeks of vertical spreads

Because the two legs offset each other, spreads have smaller Greeks than single options:

- **Delta:** directional, but less than a single option.
- **Vega:** small, so implied volatility changes matter less.
- **Theta and gamma:** depend on where price sits relative to the strikes; they change sign as the spread moves in or out of the money.

This makes verticals useful around events where implied volatility might collapse. See [Volatility Crush and Expansion](https://learn.tradelabsai.com/volatility/volatility-crush-and-expansion/).

## Managing vertical spreads

- **Take profits early:** spreads rarely reach full value until near expiration, so many traders close at 50% to 75% of maximum profit.
- **Close before expiry** if price is between the strikes to avoid pin and assignment risk. See [Exercise and Assignment](https://learn.tradelabsai.com/options/exercise-and-assignment/).
- **Roll** to a later expiry or different strikes if the view still holds.

## Common mistakes

- **Choosing widths without considering the maximum loss in dollars.**
- **Letting a spread expire with the price between strikes.**
- **Trading illiquid strikes** where the combined spread cost is large.
- **Ignoring early assignment** on short legs, especially before dividends.

## Frequently asked questions

### What is a vertical spread?

An options strategy that buys and sells options of the same type and expiration at different strike prices, capping both gain and loss.

### What is the difference between a debit and credit spread?

A debit spread costs money to open and profits from a move; a credit spread pays you to open and profits if the price stays on the right side of the short strike.

### Are vertical spreads safer than buying options?

They have a defined maximum loss like buying options, and they cost less, but they also cap profit. Their risk is lower than selling naked options.
