How are SEI 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 SEI butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 80.10%), the computed maximum profit is $324.97 per contract and the computed maximum loss is -$170.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a SEI butterfly?

The breakeven for the SEI butterfly priced on this page is roughly $80.80 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current SEI market-implied 1-standard-deviation expected move is approximately 22.96%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current SEI implied volatility affect this butterfly?

SEI ATM IV is at 80.10% with IV rank near 29.58%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

The company was formerly known as Solaris Oilfield Infrastructure, Inc. and changed its name to Solaris Energy Infrastructure, Inc. in September 2024.

SEI (Solaris Energy Infrastructure, Inc.) trades in the Energy sector, specifically Oil & Gas Equipment & Services, with a market capitalization of approximately $5.54B, a trailing P/E of 87.00, a beta of 1.26 versus the broader market, a 52-week range of 21.22-81.24, average daily share volume of 2.7M, a public-listing history dating back to 2017, approximately 364 full-time employees. These structural characteristics shape how SEI stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 1.26 places SEI roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 87.00 is on the rich side, which tends to correlate with higher earnings-window IV expansion as the market debates whether forward growth supports the multiple. SEI pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a butterfly on SEI?

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 SEI snapshot

As of May 15, 2026, spot at $78.63, ATM IV 80.10%, IV rank 29.58%, expected move 22.96%. The butterfly on SEI 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 SEI specifically: SEI IV at 80.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a SEI butterfly, with a market-implied 1-standard-deviation move of approximately 22.96% (roughly $18.06 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 SEI expiries trade a higher absolute premium for lower per-day decay. Position sizing on SEI should anchor to the underlying notional of $78.63 per share and to the trader's directional view on SEI stock.

SEI butterfly setup

The SEI 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 SEI near $78.63, the first option leg uses a $75.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SEI 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 SEI shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$75.00	$9.50
Sell 2	Call	$77.50	$8.20
Buy 1	Call	$82.50	$6.10

When traders use butterfly on SEI

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

SEI thesis for this butterfly

The market-implied 1-standard-deviation range for SEI extends from approximately $60.57 on the downside to $96.69 on the upside. A SEI long call butterfly is a pinning play: it pays maximum at the middle strike if SEI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SEI IV rank near 29.58% 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 SEI at 80.10%. As a Energy name, SEI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SEI-specific events.

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