Bear Put Spread
Buy a higher-strike put and sell a lower-strike put. A cheaper, capped bearish trade.
Payoff at expiration
When traders use it
Moderately bearish with a target near the short strike.
Formulas (per share; ×100 per contract)
| Max profit | (K1 − K2) − net debit |
| Max loss | Net debit (P1 − P2) |
| Breakeven | K1 − net debit |
Key risks
Capped profit; full debit at risk; early assignment on the short put.
How it works
You buy a put at a higher strike and sell a put at a lower strike, same expiration. Net debit = maximum loss; maximum value is the strike width.
Worked example HYPOTHETICAL
Hypothetical example only — not real prices or a recommendation. Stock at $100. Buy the $100 put for $4.00, sell the $90 put for $1.50. Net debit $2.50 ($250).
| Stock price at expiration | P/L (1 contract, excl. fees) |
|---|---|
| $80 | +$750 |
| $90 | +$750 |
| $95 | +$250 |
| $97.5 | $0 |
| $100 | −$250 |
| $110 | −$250 |
Market outlook: when to use it
Use when: Moderately bearish with a downside target near the short strike.
Avoid when: Expecting a crash far below the short strike, or a slow drift.
The Greeks, in plain words
| Delta | Negative (gains when stock falls), smaller than a long put. |
| Theta | Mixed: hurts above the long strike, helps once near/below the short strike. |
| Vega | Small. |
| Gamma | Small. |
Choosing strikes and expiration
Long put ATM or slightly ITM, short put at your target. 30–60 days.
Managing the trade
Take profit at 50–80% of max. Close before expiration if the short put is ITM to avoid assignment of shares. Short put can be assigned early when deep ITM.
Common mistakes
- Holding to expiration between strikes.
- Paying near the full width.

Explained simply
When would someone use this?
When you expect a moderate drop and want a cheaper, defined-risk bearish trade.
The setup, in plain words
Buy a put at a higher strike and sell a put at a lower strike, same expiration.
Max profit, max loss and breakeven
- Max profit
- (Higher strike − lower strike − net debit) × 100.
- Max loss
- The net debit paid.
- Breakeven
- Higher strike − net debit.
A simple numeric example (hypothetical)
Stock at $100. Buy the $100 put for $3 and sell the $90 put for $1: net cost $2 ($200). Stock at $90 or lower: profit $800. Stock at $98: breakeven. Stock at $100 or higher: loss $200.
The main risks, in plain words
- Gains stop below the lower strike.
- You can lose the whole debit if the stock does not fall.
- The short put can be assigned early.
Beginner FAQ
How is this different from a long put?
It costs less but cannot make more than the width of the strikes minus the cost.
