How are XLI 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 XLI butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 22.60%), the computed maximum profit is $634.66 per contract and the computed maximum loss is -$196.00 per contract.

Current XLI snapshot

As of June 30, 2026, spot at $184.76, ATM IV 22.60%, IV rank 61.23%, expected move 6.48%. The butterfly on XLI 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 31-day expiry.

Why this butterfly structure on XLI specifically: XLI IV at 22.60% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 6.48% (roughly $11.97 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated XLI expiries trade a higher absolute premium for lower per-day decay. Position sizing on XLI should anchor to the underlying notional of $184.76 per share and to the trader's directional view on XLI etf.

XLI butterfly setup

The XLI 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 XLI near $184.76, the first option leg uses a $176.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed XLI chain at a 31-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 XLI shares for the stock leg in covered calls and collars).

Buy 1	Call	$176.00	$10.73
Sell 2	Call	$185.00	$4.95

When traders use butterfly on XLI

Butterflies on XLI are pinning bets - traders use them when they expect XLI 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.

XLI thesis for this butterfly

The market-implied 1-standard-deviation range for XLI extends from approximately $172.79 on the downside to $196.73 on the upside. A XLI long call butterfly is a pinning play: it pays maximum at the middle strike if XLI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current XLI IV rank near 61.23% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on XLI should anchor more to the directional view and the expected-move geometry. As a Financial Services name, XLI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to XLI-specific events.

XLI 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. XLI positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move XLI alongside the broader basket even when XLI-specific fundamentals are unchanged. Always rebuild the position from current XLI chain quotes before placing a trade.
