Long Call Butterfly: A Cheap Bet That the Stock Pins a Price
You believe the stock will land at a specific price at expiration, not just stay in a range. A long call butterfly buys a call below that price, sells two calls at it, and buys one more call above it, for a small, defined-risk bet that pays its best if you are right about the exact pin.
- Exactly what you buy and sell: one call low, two calls at the middle, one call high
- The payoff: cheap, defined risk, maximum profit only at the exact middle strike
- Your numbers: net debit paid, max profit at the pin, the narrow profitable range
- When a long call butterfly fits and why it needs precision, not just direction
A long call butterfly is the sharpest, cheapest bet you can make that a stock lands at one specific price. You buy a call below your target, sell two calls right at your target, and buy one more call above it. The two sold calls fund most of the cost of the two bought calls, leaving a small net debit that pays its best only if your pin is exactly right, and expires worthless (for a small loss) if the stock lands far from your target in either direction.
What You Actually Do
Apple trades at $200. You believe it will pin exactly at $210 by expiration (perhaps after an event settles). You buy one 1-month $200 call for $8 a share, $800, sell two 1-month $210 calls for $3 a share each, $600 total, and buy one 1-month $220 call for $1 a share, $100.
Your net debit: $800 minus $600 plus $100 = $300 paid upfront. If Apple finishes exactly at $210, your $200 call is $10 ITM ($1,000), the two $210 calls expire worthless, and the $220 call is worthless, for a gross value of $1,000 minus your $300 cost = $700 max profit. If Apple finishes below $200 or above $220, you lose the full $300 debit.

The shape is a sharp peak, not a plateau. Profit is maximized exactly at $210 and tapers quickly moving away in either direction, hitting the max loss of $300 at or beyond $200 on the low side and $220 on the high side. This is a precision trade: being roughly right is not the same as being exactly right.
The Precision Trade: A Peak, Not a Plateau
A long call butterfly is the sharpest tool in the neutral family, trading breadth for precision.
A long condor spreads its short strikes apart, creating a flat profit zone that is more forgiving but caps max profit lower. A long call butterfly concentrates both short strikes at a single point, creating a sharp peak of maximum profit exactly at that price, with the profit tapering quickly in both directions. It is cheaper than a condor for the same wing width, but it demands real precision about where the stock will land, not just a general sense of direction.
The math: the middle strike is where you are betting the stock pins, often chosen around a level with technical significance, a round number, or a level implied by the options market's expected move.
When a Long Call Butterfly Fits
- You have a specific price target for expiration
- You want low-cost, defined risk
- You are comfortable with a narrow profitable range
- You only have a general directional view, not a specific price
- You are uncertain of the exact level the stock will reach
- A wider condor better matches your conviction level
A long call butterfly is for the trader with a specific, high-conviction price target, not just a general bullish or neutral lean. It is not for traders who are unsure exactly where the stock will land.
A Worked Example
Walk through three scenarios: you paid $300 upfront for the butterfly.
Apple finishes at $210, exactly on your target. Max profit realized: $700. Your pin was exact.
Apple finishes at $215, close but not exact. The $200 call is $15 ITM ($1,500), the two $210 calls are $5 ITM each ($1,000 combined liability), the $220 call is worthless. Net: $1,500 minus $1,000 minus $300 = $200 profit, positive but well below the max.
Apple finishes at $195 or $230, well outside the wings. All the value nets to zero or the structure caps out, and you lose the full $300 debit.
That is the long call butterfly: a sharp, cheap bet that pays its best only if your specific price target is exactly right.
- A long call butterfly is buying one call, selling two at the middle strike, buying one more above, betting on a precise pin.
- Max profit occurs only at the exact middle strike; max loss is the small net debit outside the wings.
- The profit zone is a sharp peak, not a wide plateau, demanding real precision about the target price.
- It fits traders with a specific price target, not just a general directional or neutral view.
Pop Quiz
Two quick checks. Pick an answer and the explanation shows up right away.
Where does a long call butterfly earn its maximum profit?
The peak profit is a single point: the middle strike, where your short calls cost nothing and your lower long call captures its full intrinsic value.
How does a long call butterfly compare to a long condor in terms of precision?
A condor's two separate short strikes create a flat, forgiving plateau. A butterfly's single short strike (doubled up) creates a sharp peak, demanding more precision.
Bottom Line
A long call butterfly is the cheapest, sharpest way to bet on a stock pinning a precise price at expiration, buying a call below, selling two at the target, and buying one more above. It fits traders with genuine conviction about a specific level, not just a general sense of direction. Reach for it when you have a real price target in mind and want to risk very little to express that view. Avoid it if your view is more general, where a long condor's wider plateau would serve you better.
