Vertical Spread

What Is a Vertical Spread?

A vertical spread is an options position made of two options on the same underlying stock, with the same expiration date and the same type, either both call options or both put options. The two options differ only in their strike price. One option is bought and the other is sold, so the trader pays one option premium and receives another. Because the sold option offsets part of the cost of the bought option, the position has a defined maximum gain and a defined maximum loss.

The name refers to the way the strike prices are listed one above the other on an options chain, rather than across different expiration dates.

How Vertical Spreads Work

Vertical spreads are usually grouped by their direction and by whether they cost money to open:

• Bull call spread: buy a lower-strike call and sell a higher-strike call. Used when a moderate rise in the price is expected.
• Bear put spread: buy a higher-strike put and sell a lower-strike put. Used when a moderate decline is expected.
• Bull put spread: sell a higher-strike put and buy a lower-strike put. Brings in a net premium.
• Bear call spread: sell a lower-strike call and buy a higher-strike call. Also brings in a net premium.

Spreads that cost money to open are called debit spreads, and those that bring in money are called credit spreads.

Calculating Risk and Reward

For a debit spread, the maximum loss is the net amount paid, and the maximum gain is the difference between the strike prices minus the net amount paid. For a credit spread, the maximum gain is the net amount received, and the maximum loss is the difference between the strike prices minus that credit. Standard equity options cover 100 shares, so per-share figures are multiplied by 100.

Maximum gain on a debit spread = (difference between strike prices − net debit) × 100

Why It Matters to Investors

A vertical spread lets an investor express a view on price direction with a known worst case, which differs from buying an option outright. The trade-off is that the gain is also capped. The result depends on where the stock price sits relative to the strikes at expiration, and the position can lose its full cost if the price moves the wrong way. Spreads also involve commissions and the risk of early assignment on short options, so the mechanics are worth studying closely. This entry is educational and is not a recommendation.
