Christmas Tree Butterfly Calculator
A Christmas tree butterfly (with calls) buys one lower call, sells three calls a couple of strikes higher, and buys two calls one strike above that. It is a skewed, cheaper relative of the standard butterfly, with a bullish-leaning profit zone and strictly defined risk.

Key characteristics
- Buy 1 call, sell 3 calls higher up, buy 2 calls one strike above: net contracts balance to zero.
- Defined risk — the maximum loss is the small net debit paid.
- Profit peaks around the short (middle) strikes, leaning bullish from the current price.
- Cheaper than a symmetrical butterfly, with a tilted, narrower payoff.
When to use a Christmas tree butterfly
Use it when you expect the stock to drift up toward a specific area and stall there. The 1-3-2 call structure concentrates the payoff around the short strikes, so it pays best if the stock lands near that level by expiration.
It is a low-cost, defined-risk way to express a "moderately higher and pinned" view — more targeted than a vertical spread and cheaper than a balanced butterfly, at the cost of a narrower, skewed profit window.
Risks and management
Because the contract counts net to zero (1 − 3 + 2), the risk is defined: away from the profit zone the structure simply expires worthless and you lose the small debit. There is no naked exposure at the wings.
The enemies are a stock that never reaches the zone or one that blows past it — either way the payoff fades. As with all butterflies, the peak value is only fully realised near expiration, so timing and strike placement matter.

- A skewed 1-3-2 call butterfly: defined risk, bullish-leaning profit zone.
- Maximum loss is just the small net debit; no naked wing risk.
- Pays best if the stock drifts to the short strikes and pins there.
- Cheaper but narrower and more directional than a balanced butterfly.
Frequently asked questions
Why is it called a Christmas tree?
The staggered 1-3-2 strike layout, drawn as a position diagram, resembles the tapering shape of a Christmas tree. It is simply an unbalanced butterfly.
Is the risk really limited?
Yes. The long and short contracts net to zero (1 − 3 + 2), so beyond the strikes the payoff flattens and your loss is capped at the net debit paid.
Can it be built with puts?
Yes — the same 1-3-2 structure with puts creates a bearish-leaning Christmas tree. The call version shown here leans bullish from the current price.
