What is a butterfly on FUL?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
FUL snapshot
As of August 14, 2026, spot at $62.41, ATM IV 34.10%, IV rank 4.77%, expected move 9.78%. The butterfly on FUL below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this butterfly structure on FUL specifically: FUL IV at 34.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a FUL butterfly, with a market-implied 1-standard-deviation move of approximately 9.78% (roughly $6.10 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FUL expiries trade a higher absolute premium for lower per-day decay. Position sizing on FUL should anchor to the underlying notional of $62.41 per share and to the trader's directional view on FUL stock.
FUL butterfly setup
The FUL butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With FUL at $62.41 on that close, the first option leg uses a $59.29 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FUL chain at a 35-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 FUL shares for the stock leg in covered calls and collars).

|---|---|---|---|

| Sell 2 | Call | $62.41 | N/A |
| Buy 1 | Call | $65.53 | N/A |

FUL thesis for this butterfly
The market-implied 1-standard-deviation range for FUL extends from approximately $56.31 on the downside to $68.51 on the upside. A FUL long call butterfly is a pinning play: it pays maximum at the middle strike if FUL settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current FUL IV rank near 4.77% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on FUL at 34.10%. As a Basic Materials name, FUL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FUL-specific events.
FUL butterfly positions are structurally neutral / pin (limited-risk, limited-reward); the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. FUL positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FUL alongside the broader basket even when FUL-specific fundamentals are unchanged. Always rebuild the position from current FUL chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on FUL?
- A butterfly on FUL is the butterfly strategy applied to FUL (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration. With FUL stock at $62.41 on the most recent close, the strikes shown on this page are snapped to the nearest listed FUL chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are FUL butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the FUL butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 34.10%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a FUL butterfly?
- The breakeven for the FUL butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The FUL market-implied 1-standard-deviation expected move in the same options snapshot is approximately 9.78%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on FUL?
- Butterflies on FUL are pinning bets - traders use them when they expect FUL to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
- How does current FUL implied volatility affect this butterfly?
- FUL ATM IV is at 34.10% with IV rank near 4.77%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
