A put spread is a bearish options strategy that involves buying and selling put options on the same underlying asset with the same expiration date but at different strike prices. The trader typically buys a higher strike put (more expensive) and sells a lower strike put (less expensive), resulting in a net debit—an upfront cost to enter the position. This setup profits if the asset declines in value, but the potential gain and loss are both capped. The maximum profit occurs if the asset closes at or below the lower strike at expiration, while the maximum loss is limited to the initial debit paid. Put spreads are often used to express a moderate bearish view with defined risk, especially around catalysts like earnings misses, macro headwinds, or technical breakdowns.
Structure of a Put Spread
- Buy a put option at a higher strike price (more expensive)
- Sell a put option at a lower strike price (less expensive)
- Both options share the same expiration date
This creates a bearish vertical debit spread, where the trader pays upfront to profit from a moderate decline in the underlying asset.
Key Traits of Put Spreads
| Feature | Description |
|---|---|
| Net Debit | Trader pays to enter (cost of long put minus premium from short put) |
| Limited Downside | Max profit occurs if the asset closes at or below the short put strike |
| Defined Risk | Max loss is the net debit paid upfront |
| Directional Bias | Bearish, but more conservative than buying a naked put |
Why Use Put Spreads?
- Reduces cost vs. buying a single put
- Ideal for targeted downside moves with capped risk
- Useful around macro catalysts, earnings misses, or technical breakdowns

Summary
A put spread is a bearish options strategy where a trader buys a higher strike put and sells a lower strike put on the same underlying asset with the same expiration date. This creates a vertical debit spread that profits from a moderate decline in the asset’s price. The maximum gain is capped and occurs if the asset closes at or below the lower strike, while the maximum loss is limited to the net debit paid upfront. Put spreads are favored for their defined risk and reduced cost compared to buying a naked put, making them ideal for expressing a tactical bearish view around catalysts like earnings misses or macro headwinds.
