How are JXX 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 JXX butterfly priced from the September 29, 2026 end-of-day chain at a 30-day expiry (ATM IV 18.10%), the computed maximum profit is $120.11 per contract and the computed maximum loss is -$77.00 per contract.

What is the breakeven for a JXX butterfly?

The breakeven for the JXX butterfly priced on this page is roughly $32.23 at expiration, derived from the September 29, 2026 end-of-day chain's premiums.

JXX snapshot

As of September 29, 2026, spot at $31.44, ATM IV 18.10%, IV rank 2.08%, expected move 5.19%. The butterfly on JXX below is built from the September 29, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 52-day expiry.

Why this butterfly structure on JXX specifically: JXX IV at 18.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a JXX butterfly, with a market-implied 1-standard-deviation move of approximately 5.19% (roughly $1.63 on the underlying). The 52-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated JXX expiries trade a higher absolute premium for lower per-day decay. Position sizing on JXX should anchor to the underlying notional of $31.44 per share and to the trader's directional view on JXX etf.

JXX butterfly setup

The JXX butterfly below is built from the September 29, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With JXX at $31.44 on that close, the first option leg uses a $30.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed JXX chain at a 52-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 JXX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$30.00	$2.25
Sell 2	Call	$31.00	$1.53
Buy 1	Call	$33.00	$0.57

When traders use butterfly on JXX

Butterflies on JXX are pinning bets - traders use them when they expect JXX 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.

JXX thesis for this butterfly

The market-implied 1-standard-deviation range for JXX extends from approximately $29.81 on the downside to $33.07 on the upside. A JXX long call butterfly is a pinning play: it pays maximum at the middle strike if JXX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current JXX IV rank near 2.08% 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 JXX at 18.10%. As a Financial Services name, JXX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to JXX-specific events.

JXX 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. JXX positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move JXX alongside the broader basket even when JXX-specific fundamentals are unchanged. Always rebuild the position from current JXX chain quotes before placing a trade.
