For the XSW butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 35.00%), the computed maximum profit is $556.07 per contract and the computed maximum loss is -$172.50 per contract.

Current XSW snapshot

As of May 15, 2026, spot at $157.07, ATM IV 35.00%, IV rank 58.70%, expected move 10.03%. The butterfly on XSW 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 XSW specifically: XSW IV at 35.00% 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 10.03% (roughly $15.76 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 XSW expiries trade a higher absolute premium for lower per-day decay. Position sizing on XSW should anchor to the underlying notional of $157.07 per share and to the trader's directional view on XSW etf.

XSW butterfly setup

The XSW 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 XSW near $157.07, the first option leg uses a $149.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed XSW 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 XSW shares for the stock leg in covered calls and collars).

Buy 1	Call	$149.00	$12.25
Sell 2	Call	$157.00	$6.90
Buy 1	Call	$165.00	$3.28

When traders use butterfly on XSW

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

XSW thesis for this butterfly

The market-implied 1-standard-deviation range for XSW extends from approximately $141.31 on the downside to $172.83 on the upside. A XSW long call butterfly is a pinning play: it pays maximum at the middle strike if XSW settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current XSW IV rank near 58.70% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on XSW should anchor more to the directional view and the expected-move geometry. As a Financial Services name, XSW options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to XSW-specific events.

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