Christmas Tree Spread: Wider Butterfly at Lower Cost

Key Takeaways

• A Christmas tree spread uses strikes A, C, D, skipping B, with legs 1 long, 3 short, 2 long at equidistant intervals.
• Maximum profit equals twice the strike width minus the debit, realized at the short strike at expiration.
• A common mistake: opening too close to expiration, where gamma overwhelms the theta advantage and small moves cause large losses.
• The structure is negative gamma, positive theta, and short vega, suited to range-bound, high-IV environments.

What It Is

The long Christmas tree spread with calls uses one expiration and four equidistant strikes A, B, C, D, but skips strike B entirely. The configuration is:

• Long one call at strike A
• Short three calls at strike C
• Long two calls at strike D

The put version mirrors the layout: long one put at D, short three puts at B, long two puts at A. Both versions open for a net debit. Maximum profit happens at strike C for the call version (or B for the put version) at expiration. The shape on a payoff graph resembles a slanted evergreen tree with a long body on one side and a short tail on the other.

The Intuition

A standard long call butterfly profits in a narrow window centred on the middle strike. A Christmas tree widens that window and lowers the maximum payoff. By skipping a strike, the trader saves on premium relative to a butterfly that uses every strike, and the saved premium funds a wider profit zone.

The trade fits a view that says price will probably end somewhere in a range with one preferred level. If you have a clear opinion that the underlying drifts toward a target price by expiration, but you want more forgiveness than a butterfly offers, the Christmas tree is the structure designed for that.

How It Works

Let strikes be A < B < C < D, equidistant by width W. Let net debit be P. For the call version, expiration payoff per share is:

S <= A:  -P
A < S <= C:  (S - A) - P
C < S <= D:  (S - A) - 3(S - C) - P = -2S + A + 3C - P
S > D:  (S - A) - 3(S - C) + 2(S - D) - P = (3C - A - 2D) - P = -P

The third line shows max profit occurs at S = C, equal to (C - A) - P = 2W - P. Above strike D the position returns to the original debit because the two long calls cap losses, so the right tail is flat.

max profit = 2W - P  at S = C
lower breakeven = A + P
upper breakeven = (3C - A - P) / 2  for the call version
left of A: full debit lost
right of D: full debit lost

The Greek profile near the centre is negative gamma, positive theta, and slightly negative vega. Time decay is the main engine. McMillan classifies the structure with butterflies and condors as a "limited-risk, range-bound" trade.

Worked Example

Stock XYZ trades at $100 with 45 days to expiration. You open a long Christmas tree with calls using equidistant strikes spaced $5 apart:

• Buy one 95 call for $7.00
• Skip strike 100
• Sell three 105 calls for $2.20 each
• Buy two 110 calls for $1.10 each

Net debit: 7.00 - 6.60 + 2.20 = 2.60. Per contract set, $260.

  |___________/________\______________
  |     A=95   C=105   D=110
  |          (skipped B=100)
  | -P        max=$740      flat at -P

max profit = 2(5) - 2.60 = $7.40 per share, $740 per contract set at S=$105
lower breakeven = 95 + 2.60 = $97.60
upper breakeven = (3(105) - 95 - 2.60) / 2 = $108.70
loss at S <= 95 or S >= 110: -$260 (full debit)

Three outcomes:

• XYZ closes at $96. Long 95 call worth $1, others worthless. Loss = $260 - $100 = $160 loss.
• XYZ closes at $105. Max profit. Long 95 worth $10, others zero. $740 profit.
• XYZ closes at $115. All legs in money, position returns to flat at -P. $260 loss.

Common Mistakes

1. Treating it as a butterfly with one extra leg. It has six contracts, three strikes, and asymmetric leg counts. The cost structure, breakeven math, and theta curve all differ from a standard butterfly. Run the payoff diagram before committing capital.

2. Opening too close to expiration. Christmas trees rely on theta and on price drifting near the centre strike. With 7 to 10 days left, gamma dominates and a small move blows up the trade. Most practitioners enter with 30 to 60 days to go and manage well before expiration.

3. Ignoring bid-ask spread costs. Six legs means twelve bid-ask crossings round trip if you exit by closing each leg. Use combo or complex order types where the platform supports them and check fill quality on the entire structure, not on individual legs.

4. Skipping the wrong strike. The whole point of the structure is the skipped strike, which shifts the cost and the breakevens. Skipping B versus skipping C gives a different payoff shape. Confirm which version the order ticket built before submitting.

Frequently Asked Questions

Q: What is a Christmas tree spread in simple terms? It is a six-contract options structure that buys at one strike, skips a strike, sells three at the next, and buys two at the furthest. It profits when the underlying lands near the short strikes at expiration.

Q: How does a Christmas tree spread affect investment decisions? It targets a specific price with a wider profit zone and smaller debit than a standard butterfly, at the cost of a more complex leg count and higher bid-ask friction on entry and exit.

Q: What is a real-world example of a Christmas tree spread? With XYZ at $100, buy one 95 call, sell three 105 calls, and buy two 110 calls. Net debit $2.60. Maximum profit $7.40 at $105; full debit lost below $95 or above $110.

Q: How can investors manage a Christmas tree spread effectively? Enter with 30 to 60 days to expiration and plan to close at 50 percent of maximum profit rather than holding to expiration. Use combo order types to avoid crossing six bid-ask spreads individually.

Q: How is a Christmas tree spread different from a standard butterfly? A butterfly uses four equidistant strikes with equal wing counts. A Christmas tree skips the second strike and overweights the short leg, producing a wider profit zone at lower cost but with more leg complexity.
