What is a butterfly on JBI?
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.
Current JBI snapshot
As of May 15, 2026, spot at $4.83, ATM IV 28.40%, IV rank 0.44%, expected move 8.14%. The butterfly on JBI below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 34-day expiry.
Why this butterfly structure on JBI specifically: JBI IV at 28.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a JBI butterfly, with a market-implied 1-standard-deviation move of approximately 8.14% (roughly $0.39 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated JBI expiries trade a higher absolute premium for lower per-day decay. Position sizing on JBI should anchor to the underlying notional of $4.83 per share and to the trader's directional view on JBI stock.
JBI butterfly setup
The JBI 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 JBI near $4.83, the first option leg uses a $4.59 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed JBI chain at a 34-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 JBI shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $4.59 | N/A |
| Sell 2 | Call | $4.83 | N/A |
| Buy 1 | Call | $5.07 | N/A |

When traders use butterfly on JBI
Butterflies on JBI are pinning bets - traders use them when they expect JBI 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.
JBI thesis for this butterfly
The market-implied 1-standard-deviation range for JBI extends from approximately $4.44 on the downside to $5.22 on the upside. A JBI long call butterfly is a pinning play: it pays maximum at the middle strike if JBI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current JBI IV rank near 0.44% 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 JBI at 28.40%. As a Industrials name, JBI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to JBI-specific events.
JBI 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. JBI positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move JBI alongside the broader basket even when JBI-specific fundamentals are unchanged. Always rebuild the position from current JBI chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on JBI?
- A butterfly on JBI is the butterfly strategy applied to JBI (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 JBI stock trading near $4.83, the strikes shown on this page are snapped to the nearest listed JBI chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are JBI 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 JBI butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 28.40%), 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 JBI butterfly?
- The breakeven for the JBI butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current JBI market-implied 1-standard-deviation expected move is approximately 8.14%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
