What is a butterfly on BCAB?
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 BCAB snapshot
As of June 30, 2026, spot at $4.00, ATM IV 19.50%, IV rank 0.40%, expected move 5.59%. The butterfly on BCAB 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 17-day expiry.
Why this butterfly structure on BCAB specifically: BCAB IV at 19.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a BCAB butterfly, with a market-implied 1-standard-deviation move of approximately 5.59% (roughly $0.22 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BCAB expiries trade a higher absolute premium for lower per-day decay. Position sizing on BCAB should anchor to the underlying notional of $4.00 per share and to the trader's directional view on BCAB stock.
BCAB butterfly setup
The BCAB 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 BCAB near $4.00, the first option leg uses a $3.80 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BCAB chain at a 17-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 BCAB shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $3.80 | N/A |
| Sell 2 | Call | $4.00 | N/A |
| Buy 1 | Call | $4.20 | N/A |

When traders use butterfly on BCAB

BCAB thesis for this butterfly
The market-implied 1-standard-deviation range for BCAB extends from approximately $3.78 on the downside to $4.22 on the upside. A BCAB long call butterfly is a pinning play: it pays maximum at the middle strike if BCAB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BCAB IV rank near 0.40% 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 BCAB at 19.50%. As a Healthcare name, BCAB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BCAB-specific events.
BCAB 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. BCAB positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BCAB alongside the broader basket even when BCAB-specific fundamentals are unchanged. Always rebuild the position from current BCAB chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on BCAB?
- A butterfly on BCAB is the butterfly strategy applied to BCAB (stock).

With BCAB stock trading near $4.00, the strikes shown on this page are snapped to the nearest listed BCAB chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are BCAB butterfly max profit and max loss calculated?

Two breakevens at lower-wing plus debit and upper-wing minus debit.

Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a BCAB butterfly?
- The breakeven for the BCAB 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 BCAB market-implied 1-standard-deviation expected move is approximately 5.59%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
