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 IBND snapshot
As of May 15, 2026, spot at $31.25, ATM IV 51.10%, IV rank 6.81%, expected move 14.65%. The butterfly on IBND 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 IBND specifically: IBND IV at 51.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a IBND butterfly, with a market-implied 1-standard-deviation move of approximately 14.65% (roughly $4.58 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 IBND expiries trade a higher absolute premium for lower per-day decay. Position sizing on IBND should anchor to the underlying notional of $31.25 per share and to the trader's directional view on IBND etf.
IBND butterfly setup
The IBND 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 IBND near $31.25, the first option leg uses a $29.69 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IBND 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 IBND shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $29.69 | N/A |
| Sell 2 | Call | $31.25 | N/A |
| Buy 1 | Call | $32.81 | N/A |

IBND thesis for this butterfly
The market-implied 1-standard-deviation range for IBND extends from approximately $26.67 on the downside to $35.83 on the upside. A IBND long call butterfly is a pinning play: it pays maximum at the middle strike if IBND settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current IBND IV rank near 6.81% 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 IBND at 51.10%. As a Financial Services name, IBND options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IBND-specific events.
IBND 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. IBND positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IBND alongside the broader basket even when IBND-specific fundamentals are unchanged. Always rebuild the position from current IBND chain quotes before placing a trade.
