What is a butterfly on INBX?
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 INBX snapshot
As of May 15, 2026, spot at $111.19, ATM IV 85.20%, IV rank 10.19%, expected move 24.43%. The butterfly on INBX 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 INBX specifically: INBX IV at 85.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a INBX butterfly, with a market-implied 1-standard-deviation move of approximately 24.43% (roughly $27.16 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 INBX expiries trade a higher absolute premium for lower per-day decay. Position sizing on INBX should anchor to the underlying notional of $111.19 per share and to the trader's directional view on INBX stock.
INBX butterfly setup
The INBX 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 INBX near $111.19, the first option leg uses a $105.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed INBX 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 INBX shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $110.00 | $11.80 |

When traders use butterfly on INBX
Butterflies on INBX are pinning bets - traders use them when they expect INBX 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.
INBX thesis for this butterfly
The market-implied 1-standard-deviation range for INBX extends from approximately $84.03 on the downside to $138.35 on the upside. A INBX long call butterfly is a pinning play: it pays maximum at the middle strike if INBX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current INBX IV rank near 10.19% 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 INBX at 85.20%. As a Healthcare name, INBX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to INBX-specific events.
INBX 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. INBX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move INBX alongside the broader basket even when INBX-specific fundamentals are unchanged. Always rebuild the position from current INBX chain quotes before placing a trade.
