LONG RATIO PUT SPREAD
Overview
Sell one higher-strike put and buy two lower-strike puts. Often structured for a small credit. Limited loss if the stock barely moves; large profits if the stock crashes hard below both long put strikes.
What it does
The bearish analog to the call backspread. You sell one higher-strike put and buy two lower-strike puts — ideally for a credit. If the stock crashes, two long puts accelerate your profits. If the stock rallies, both sides expire worthless and you keep the small credit. The only bad zone is the stock landing exactly at the long put strike at expiration, producing the maximum loss.
Structure
sell 1 put + buy 2 puts
Setup
- 1.Sell 1 Put at a higher strike.
- 2.Buy 2 Puts at a lower strike.
- 3.Same expiration.
Max profit
Substantial to the downside — two long puts benefit from a large price decline.
Max loss
Limited. (Long Strike − Short Strike − Net Credit) × 100 if the stock finishes exactly at the long put strike.
Breakeven
Upper: Short Strike + Net Credit. Lower: Long Strike − Max Profit per Share.
When to use
When you're very bearish and expect a large downside move. Best structured for a credit so there's no loss if the stock rallies.
When to avoid
When you expect the stock to stay flat — maximum loss occurs near the long put strike.
Example trade
Stock: AAPL at $160 Sell 1 AAPL $160 Put at $5.20 Buy 2 AAPL $150 Puts at $2.50 each (debit $5.00) Net Credit: $0.20 ($20) Expiration: 30 days If AAPL rallies to $170: Both sides expire worthless; Profit = $20 If AAPL crashes to $130: 2 long puts worth $20 each; P&L = ($40 - $10 + $0.20) × 100 = $3,020 Max Loss: ($160 - $150 - $0.20) × 100 = $980 if AAPL pins at $150
Common mistakes
- ×Paying a debit instead of receiving a credit — changes the downside protection significantly.
- ×Setting long put strikes too far OTM — requires an even larger decline to profit.
- ×Holding through low-IV environments where the two long puts lose value rapidly without a move.
- ×Ignoring the max loss zone near the long puts — the 'sweet spot' for loss is a moderate decline that stops exactly there.
- ×Using on stocks that are already near support — limited decline potential reduces edge.
FAQ
What is the ideal outcome for a put backspread?
A significant, fast decline well below the long put strikes — the two long puts generate large profits that dwarf the spread cost.
What happens if I enter for a debit instead of credit?
You lose money if the stock rallies AND if it makes only a moderate decline. You need a bigger crash to overcome the debit paid.
