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.
Current BBNX snapshot
As of May 15, 2026, spot at $9.32, ATM IV 141.40%, expected move 40.54%. The butterfly on BBNX 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 BBNX specifically: IV rank is unavailable in the current snapshot, so regime-based timing for BBNX is inferred from ATM IV at 141.40% alone, with a market-implied 1-standard-deviation move of approximately 40.54% (roughly $3.78 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 BBNX expiries trade a higher absolute premium for lower per-day decay. Position sizing on BBNX should anchor to the underlying notional of $9.32 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 near $9.32, the first option leg uses a $8.85 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 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 BBNX shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $8.85 | N/A |
| Sell 2 | Call | $9.32 | N/A |
| Buy 1 | Call | $9.79 | 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 $5.54 on the downside to $13.10 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. 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 trading near $9.32, the strikes shown on this page are snapped to the nearest listed BBNX chain strike and the premiums come straight from the end-of-day 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 141.40%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract.

- 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 end-of-day chain premiums.

The current BBNX market-implied 1-standard-deviation expected move is approximately 40.54%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
