How are SNEX 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 SNEX butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 52.20%), the computed maximum profit is $380.62 per contract and the computed maximum loss is -$110.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a SNEX butterfly?

The breakeven for the SNEX butterfly priced on this page is roughly $111.10 and $118.90 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 SNEX market-implied 1-standard-deviation expected move is approximately 14.97%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

Current SNEX snapshot

As of June 29, 2026, spot at $115.67, ATM IV 52.20%, IV rank 9.83%, expected move 14.97%. The butterfly on SNEX 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 18-day expiry.

Why this butterfly structure on SNEX specifically: SNEX IV at 52.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a SNEX butterfly, with a market-implied 1-standard-deviation move of approximately 14.97% (roughly $17.31 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SNEX expiries trade a higher absolute premium for lower per-day decay. Position sizing on SNEX should anchor to the underlying notional of $115.67 per share and to the trader's directional view on SNEX stock.

SNEX butterfly setup

The SNEX 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 SNEX near $115.67, the first option leg uses a $110.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SNEX chain at a 18-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 SNEX shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$110.00	$8.90
Sell 2	Call	$115.00	$6.00
Buy 1	Call	$120.00	$4.20

When traders use butterfly on SNEX

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

SNEX thesis for this butterfly

The market-implied 1-standard-deviation range for SNEX extends from approximately $98.36 on the downside to $132.98 on the upside. A SNEX long call butterfly is a pinning play: it pays maximum at the middle strike if SNEX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SNEX IV rank near 9.83% 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 SNEX at 52.20%. As a Financial Services name, SNEX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SNEX-specific events.

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