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 straddle on SEI?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the 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 straddle 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 straddle 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 straddle, 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 straddle setup

The SEI straddle 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 $77.50 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).

When traders use straddle on SEI

Straddles on SEI are pure-volatility plays that profit from large moves in either direction; traders typically buy SEI straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

SEI thesis for this straddle

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 straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. 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 straddle positions are structurally neutral / high-volatility (long premium); 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.

Frequently asked questions

What is a straddle on SEI?

A straddle on SEI is the straddle strategy applied to SEI (stock). The strategy is structurally neutral / high-volatility (long premium): A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

How are SEI straddle max profit and max loss calculated?

The breakeven for the SEI straddle priced on this page is roughly $62.40 and $92.60 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.
