What is a butterfly on IIIN?
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 IIIN snapshot
As of June 30, 2026, spot at $29.95, ATM IV 55.40%, IV rank 11.87%, expected move 15.88%. The butterfly on IIIN 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 IIIN specifically: IIIN IV at 55.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a IIIN butterfly, with a market-implied 1-standard-deviation move of approximately 15.88% (roughly $4.76 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 IIIN expiries trade a higher absolute premium for lower per-day decay. Position sizing on IIIN should anchor to the underlying notional of $29.95 per share and to the trader's directional view on IIIN stock.
IIIN butterfly setup
The IIIN 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 IIIN near $29.95, the first option leg uses a $28.45 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IIIN 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 IIIN shares for the stock leg in covered calls and collars).

|---|---|---|---|

| Sell 2 | Call | $29.95 | N/A |
| Buy 1 | Call | $31.45 | N/A |

IIIN thesis for this butterfly
The market-implied 1-standard-deviation range for IIIN extends from approximately $25.19 on the downside to $34.71 on the upside. A IIIN long call butterfly is a pinning play: it pays maximum at the middle strike if IIIN settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current IIIN IV rank near 11.87% 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 IIIN at 55.40%. As a Industrials name, IIIN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IIIN-specific events.
IIIN 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. IIIN positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IIIN alongside the broader basket even when IIIN-specific fundamentals are unchanged. Always rebuild the position from current IIIN chain quotes before placing a trade.

- How are IIIN butterfly max profit and max loss calculated?
