Backspread
A backspread sells one option and buys more further out, betting on a big move. Learn how it flips a ratio spread to give unlimited upside and limited risk.
A backspread sells one option and buys a larger number further out of the money, usually in a 1-by-2 ratio. It is the exact flip of a ratio spread: instead of being net short options, you are net long options, so you profit from a big move and your risk is limited.
If a ratio spread is a bet the stock lands at a target, a backspread is a bet the stock blows through it. Let me show you the mirror image.
Net Long the Move
A ratio spread buys one and sells two, leaving you net short an option with open-ended risk. A backspread reverses the ratio: you sell one and buy two, which leaves you net long an option.
That extra long option changes everything. Now a big move in your direction pays off without a ceiling, because you own more options than you sold. The single option you sold helps fund the two you bought, so you can often enter for a small cost or even a credit. Your worst case is a stock that stalls in the middle, and even that loss is capped.
Watch It Work
Apple is at $200 and you expect a sharp rally, a real breakout, not a drift. You build a call backspread:
- Sell one $200 call for $6 a share
- Buy two $210 calls for $3 a share each, costing $6
- Net cost: about zero
Apple explodes to $250. Your two $210 calls are each worth $40 a share, or $8,000 together. The single $200 call you sold costs you $50 a share, or $5,000. You net a large profit, and the higher Apple goes, the more you make, because you own one more call than you are short.
Apple stalls around $210 at expiration. This is the worst case. The $200 call you sold is worth $10 while your two $210 calls expire worthless. You take a limited loss here, the widest point of the dip, and it is capped no matter what.
Apple sits at $200 or drops. Everything expires near worthless. You lose little or nothing, since you entered for about zero cost.
When to Use It
A backspread is a directional bet on volatility and a large move, with a friendly risk shape.
The appeal is unlimited profit on a big move in your chosen direction, paired with a capped loss and a cheap or free entry. A call backspread wants a violent rally; a put backspread wants a hard crash.
The trade-off is that a modest move is the losing case. If the stock drifts only to the short strike and stops, you sit at the bottom of the dip. Backspreads reward conviction that the move will be big, and they benefit from rising implied volatility since you are net long options. Get a sleepy stock and the position quietly bleeds toward its capped loss.
- A backspread sells one option and buys more, leaving you net long.
- It offers unlimited profit on a big move and a capped loss.
- It often costs little or nothing to enter.
- Its worst case is a stock that stalls at the short strike.
Pop Quiz
Three quick questions to see what stuck. Pick an answer and the explanation shows up right away.
How does a backspread differ from a ratio spread?
A backspread flips the ratio: sell one, buy two, so you are net long and profit from a big move.
What does a call backspread want the stock to do?
Being net long calls, it profits most from a sharp rally, with unlimited upside.
What is the worst case for a backspread?
A stall at the short strike sits at the bottom of the dip, but the loss there is limited and known.
Bottom Line
A backspread is the ratio spread turned inside out. Sell one option, buy two further out, and you flip from net short to net long: unlimited profit on a big move, a capped loss, and often a free entry. It rewards a stock that breaks out hard.
The one thing it dislikes is the middle. A stock that drifts only to the short strike and stops leaves you at the deepest point of the loss. Use a backspread when you expect a violent move and want limited risk while you wait for it.
Keep going: the flipped mirror is the ratio spread, and the pure motion bets are the long straddle and long strangle.
