How are XAR 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 XAR butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 30.30%), the computed maximum profit is $843.84 per contract and the computed maximum loss is -$650.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

Current XAR snapshot

As of May 15, 2026, spot at $261.37, ATM IV 30.30%, IV rank 54.90%, expected move 8.69%. The butterfly on XAR 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 63-day expiry.

Why this butterfly structure on XAR specifically: XAR IV at 30.30% 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 8.69% (roughly $22.70 on the underlying). The 63-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated XAR expiries trade a higher absolute premium for lower per-day decay. Position sizing on XAR should anchor to the underlying notional of $261.37 per share and to the trader's directional view on XAR etf.

XAR butterfly setup

The XAR 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 XAR near $261.37, the first option leg uses a $250.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed XAR chain at a 63-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 XAR shares for the stock leg in covered calls and collars).

When traders use butterfly on XAR

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

XAR thesis for this butterfly

The market-implied 1-standard-deviation range for XAR extends from approximately $238.67 on the downside to $284.07 on the upside. A XAR long call butterfly is a pinning play: it pays maximum at the middle strike if XAR settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current XAR IV rank near 54.90% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on XAR should anchor more to the directional view and the expected-move geometry. As a Financial Services name, XAR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to XAR-specific events.

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