What is a butterfly on BBNX?
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.
BBNX snapshot
As of August 14, 2026, spot at $17.86, ATM IV 228.10%, IV rank 45.43%, expected move 65.39%. The butterfly on BBNX 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 BBNX specifically: BBNX IV at 228.10% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 65.39% (roughly $11.68 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 BBNX expiries trade a higher absolute premium for lower per-day decay. Position sizing on BBNX should anchor to the underlying notional of $17.86 per share and to the trader's directional view on BBNX stock.
BBNX butterfly setup
The BBNX 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 BBNX at $17.86 on that close, the first option leg uses a $16.97 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BBNX 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 BBNX shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $16.97 | N/A |
| Sell 2 | Call | $17.86 | N/A |
| Buy 1 | Call | $18.75 | N/A |

When traders use butterfly on BBNX
Butterflies on BBNX are pinning bets - traders use them when they expect BBNX 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.
BBNX thesis for this butterfly
The market-implied 1-standard-deviation range for BBNX extends from approximately $6.18 on the downside to $29.54 on the upside. A BBNX long call butterfly is a pinning play: it pays maximum at the middle strike if BBNX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BBNX IV rank near 45.43% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on BBNX should anchor more to the directional view and the expected-move geometry. As a Healthcare name, BBNX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BBNX-specific events.
BBNX 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. BBNX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BBNX alongside the broader basket even when BBNX-specific fundamentals are unchanged. Always rebuild the position from current BBNX chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on BBNX?
- A butterfly on BBNX is the butterfly strategy applied to BBNX (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 BBNX stock at $17.86 on the most recent close, the strikes shown on this page are snapped to the nearest listed BBNX chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are BBNX 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 BBNX butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 228.10%), 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 BBNX butterfly?
- The breakeven for the BBNX 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 BBNX market-implied 1-standard-deviation expected move in the same options snapshot is approximately 65.39%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
