This is a follow-up to the butterfly basics — more worked examples covering the common variations, plus a practical walkthrough of how traders actually build and manage these trades.
Part 1: More Examples
Example A: The Classic Symmetric Call Butterfly
Setup: Stock XYZ trades at $100. You think it'll stay close to $100 through expiration.
- Buy 1 call at $95 strike for $7.00
- Sell 2 calls at $100 strike for $4.00 each ($8.00 total collected)
- Buy 1 call at $105 strike for $2.00
Net cost: $7.00 − $8.00 + $2.00 = $1.00 debit (this is your max loss, per share — $100 for one full spread)
| Stock at expiration | What happens | Result |
|---|---|---|
| $90 | All calls worthless | Lose $1.00 (full premium) |
| $95 | All calls worthless | Lose $1.00 |
| $100 | $95 call worth $5, others worthless | Profit: $5 − $1 = $4.00 (max profit) |
| $105 | $95 call worth $10, two $100 calls cost $10 to close, $105 call worthless | Back near breakeven |
| $110 | Everything cancels out | Lose $1.00 (full premium) |
Shape: A symmetric tent — small, equal loss ($1.00) on both far ends, peak profit ($4.00) right at $100, the strike where you sold your calls.
This is the "textbook" version — cheap to put on, small defined risk, big payoff only if the stock lands almost exactly on your middle strike.
Example B: A Put Butterfly (Same Idea, Using Puts)
Butterflies work with puts too, and behave the same way — this one just uses put options instead of calls, but the payoff shape is identical.
Setup: Stock ABC trades at $50.
- Buy 1 put at $45 for $1.00
- Sell 2 puts at $50 for $3.00 each ($6.00 total collected)
- Buy 1 put at $55 for $6.50
Net cost: $1.00 − $6.00 + $6.50 = $1.50 debit
Max profit happens if ABC lands exactly at $50 at expiration. Max loss ($1.50) happens if ABC finishes far above $55 or far below $45.
Why use puts instead of calls? Mostly personal preference or slight pricing differences between calls and puts (skew) — the strategy and shape are functionally the same either way.
Example C: The Iron Butterfly (Selling Instead of Buying)
An iron butterfly flips the whole idea around — instead of paying a small debit for a shot at a big profit, you collect a credit upfront and profit if the stock stays still, similar in spirit to the earlier butterfly examples but built with both calls and puts together.
Setup: Stock DEF trades at $75.
- Sell 1 call at $75 for $3.00
- Buy 1 call at $80 for $1.00
- Sell 1 put at $75 for $3.00
- Buy 1 put at $70 for $1.00
Net credit collected: $3.00 + $3.00 − $1.00 − $1.00 = $4.00 (this is your max profit) Max loss: the width of either wing ($5) minus the credit = $5 − $4 = $1.00
| Stock at expiration | Result |
|---|---|
| $75 (pins right at the middle) | Keep the full $4.00 credit — max profit |
| $77 or $73 | Partial profit |
| $80 or above | Max loss: $1.00 |
| $70 or below | Max loss: $1.00 |
Key difference from the debit butterfly: you want the stock to do nothing here, and time decay works in your favor every day, instead of against you. This is popular for range-bound, low-movement stocks or during quiet periods.
Example D: A "Broken Wing" Butterfly, Built for a Small Credit
This connects back to the two real MDB charts from before — traders often widen one side of the butterfly on purpose so the trade can be built for a net credit or near-zero cost, removing risk entirely on one side.
Setup: Stock GHI trades at $60. You think it's more likely to go up than down.
- Buy 1 call at $60 for $4.00
- Sell 2 calls at $65 for $2.50 each ($5.00 total collected)
- Buy 1 call at $75 (wider than usual, instead of $70) for $0.60
Net cost: $4.00 − $5.00 + $0.60 = $0.40 net debit — cheap, and because the top wing is wider, there's no loss if the stock skyrockets; you just give back most of the profit gradually instead of hitting a hard wall.
This is exactly the shape you saw in the first MDB example — flat capped loss on one side, a profit peak, then a gentle decline that stays positive even on a big move.
Part 2: How to Actually Trade a Butterfly
Step 1 — Pick a stock you expect to be range-bound
Butterflies work best when you have a specific price target and expect low-to-moderate movement, not a huge swing. Good candidates:
- Stocks that just had their big move already (e.g., right after earnings, once IV has settled down)
- Range-bound or "boring" stocks
- Index ETFs during quiet market periods
Avoid butterflies right before a known volatile event (earnings, FDA rulings) unless you're specifically building the trade around an expected post-event price.
Step 2 — Choose your center strike
This is your price target — where you think the stock will land by expiration. This strike is where your max profit sits, so accuracy matters more here than in almost any other options strategy.
Step 3 — Choose the width of your wings
- Narrow wings (strikes close together) = cheaper trade, smaller max loss, smaller max profit, but you need to be very precise about where the stock lands.
- Wide wings (strikes far apart) = costs more, bigger max loss, bigger max profit, but gives you more room to be "close enough."
A common approach: pick a width based on the stock's expected move (using something like the Rule of 16 to estimate a realistic daily/weekly range).
Step 4 — Pick your expiration date
- Shorter expirations (days to a couple weeks) are common for butterflies because time decay accelerates near expiration, and that decay is what drives the profit — you want the stock to be near your center strike right as the fastest decay is happening.
- Longer expirations give the stock more time to drift away from your target, which usually isn't what you want with this strategy.
Step 5 — Check implied volatility
- Debit butterflies (Examples A, B, D) generally work best when IV is elevated but expected to drop — you benefit if the market's uncertainty fades and the stock settles near your strike.
- Iron butterflies (Example C) are also often placed when IV is high, since you're collecting a bigger credit upfront.
Step 6 — Know your exit plan before you enter
Butterflies can be very sensitive to price movement near the center strike as expiration nears — profits can appear and disappear quickly. A common approach:
- Take profit early if you're at 50–75% of max profit — don't get greedy waiting for the exact peak.
- Cut the loss early if the stock moves clearly outside your wings well before expiration, rather than holding to the bitter end.
- Watch the position daily in the final week, since these trades often move fastest right before expiration.
Step 7 — Consider adjustments (optional, more advanced)
Some traders "roll" one side of the butterfly if the stock starts drifting toward one wing — for example, widening the wing on the side the stock is approaching, similar to the broken wing setup in Example D. This trades some potential profit for reduced risk, but adds complexity and isn't necessary for a beginner's first few trades.
Quick Cheat Sheet
| Strategy | You pay or collect? | Best when | Max risk |
|---|---|---|---|
| Standard call/put butterfly | Pay (small debit) | You expect the stock to land near a specific price | Debit paid |
| Iron butterfly | Collect (credit) | You expect the stock to stay flat, IV is elevated | Wing width − credit |
| Broken wing butterfly | Pay (often very small) or even collect | You lean one direction but still want a "flat" profit zone | Only on the narrow side |

This isn't a trade recommendation, and I'm not a financial advisor — real trades should be sized and structured based on your own account, risk tolerance, and research, ideally with input from a licensed professional.
