What is a Put Backspread?
A put backspread is the reverse of a put ratio spread. You sell one put at a higher strike and buy two puts at a lower strike, all at the same expiration. The trade profits from a big downside move. The two long puts accelerate in value as the stock drops, far outpacing the single short put.
This is a bearish volatility play. You want the stock to crash. If it stays flat or goes up, you keep any net credit or lose a small debit. The worst case is a moderate drop to the long put strike, where you are exposed to the full spread width.
How to Set It Up
- Sell 1 put at a higher strike
- Buy 2 puts at a lower strike
- Same expiration for all legs
- Strike selection: Sell the ATM or slightly ITM put. Buy two puts 5-10 points lower.
- Credit or debit: Often entered for a small credit when the short put is near the money.
- Expiration: Allow enough time for the expected move. 30-60 days is typical.
The net credit or debit depends on the strikes and IV environment.
When to Use This Strategy
Use a put backspread when:
- You expect a significant downside move or crash
- You want to profit from bearish volatility with defined risk
- A negative catalyst is expected — bad earnings, economic downturn, regulatory issues
- You want a cheaper alternative to buying two puts outright
- IV is low and you expect a spike from a selloff
Put backspreads are the go-to trade when you think something is about to break. They are popular as crash protection or event-driven bearish bets.
Example Trade
Stock XYZ is trading at $100. You expect bad news that could push it below $90.
- Sell 1 XYZ $100 put for $3.80
- Buy 2 XYZ $95 puts for $2.00 each ($4.00 total)
- Net debit: $4.00 - $3.80 = $0.20 ($20 total)
If XYZ stays at $100 or goes up: All puts expire worthless. You lose the $20 debit.
If XYZ drops to $95: The $100 put is worth $5 (-$500). The two $95 puts expire worthless. Net: -$500 - $20 = -$520 loss. This is the max loss zone.
If XYZ drops to $85: The $100 put is worth $15 (-$1,500). The two $95 puts are worth $10 each (+$2,000). Net: $2,000 - $1,500 - $20 = $480 profit.
If XYZ drops to $70: The $100 put is worth $30 (-$3,000). The two $95 puts are worth $25 each (+$5,000). Net: $5,000 - $3,000 - $20 = $1,980 profit.
Risk and Reward
- Max profit: Substantial (stock can only drop to zero). In theory, (long strike - debit) x 2 - (short strike x 100). Profits grow as the stock drops further.
- Max loss: Occurs at the long put strike at expiration. In our example, $520.
- Breakeven: On the downside, the long strike minus the max loss per share (roughly $89.80). On the upside, if entered for a credit, anywhere above the short strike.
The V-shaped payoff means the worst case is a moderate drop. Big drops or no drops are both favorable outcomes.
Tips and Common Mistakes
- You need a real crash, not a small dip. A 5% drop to the long strike is the worst case. You need a bigger move.
- Enter for a credit when possible to eliminate upside risk.
- Use longer expirations for more time to let the move happen.
- Consider this as portfolio insurance. Even if you lose the small debit most of the time, the trade pays off big when the market sells off sharply.
