How are XLU 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 XLU butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 15.42%), the computed maximum profit is $83.64 per contract and the computed maximum loss is -$144.00 per contract.

The breakeven for the XLU butterfly priced on this page is roughly $44.44 and $46.56 at expiration, derived from end-of-day chain premiums.

Current XLU snapshot

As of June 30, 2026, spot at $45.50, ATM IV 15.42%, IV rank 20.73%, expected move 4.42%. The butterfly on XLU 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 XLU specifically: XLU IV at 15.42% is on the cheap side of its 1-year range, which favors premium-buying structures like a XLU butterfly, with a market-implied 1-standard-deviation move of approximately 4.42% (roughly $2.01 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 XLU expiries trade a higher absolute premium for lower per-day decay. Position sizing on XLU should anchor to the underlying notional of $45.50 per share and to the trader's directional view on XLU etf.

XLU butterfly setup

The XLU 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 XLU near $45.50, the first option leg uses a $43.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed XLU 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 XLU shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$43.00	$3.14
Sell 2	Call	$45.50	$0.95
Buy 1	Call	$48.00	$0.19

When traders use butterfly on XLU

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

XLU thesis for this butterfly

The market-implied 1-standard-deviation range for XLU extends from approximately $43.49 on the downside to $47.51 on the upside. A XLU long call butterfly is a pinning play: it pays maximum at the middle strike if XLU settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current XLU IV rank near 20.73% 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 XLU at 15.42%. As a Financial Services name, XLU options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to XLU-specific events.

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