How are SUPN 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 SUPN butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 40.10%), the computed maximum profit is $171.28 per contract and the computed maximum loss is -$117.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a SUPN butterfly?

The breakeven for the SUPN butterfly priced on this page is roughly $44.11 and $47.83 at expiration, derived from end-of-day chain premiums.

Current SUPN snapshot

As of June 29, 2026, spot at $46.34, ATM IV 40.10%, IV rank 5.31%, expected move 11.50%. The butterfly on SUPN 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 SUPN specifically: SUPN IV at 40.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a SUPN butterfly, with a market-implied 1-standard-deviation move of approximately 11.50% (roughly $5.33 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 SUPN expiries trade a higher absolute premium for lower per-day decay. Position sizing on SUPN should anchor to the underlying notional of $46.34 per share and to the trader's directional view on SUPN stock.

SUPN butterfly setup

The SUPN 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 SUPN near $46.34, the first option leg uses a $44.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SUPN 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 SUPN shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$44.00	$3.05
Sell 2	Call	$46.00	$1.80
Buy 1	Call	$49.00	$0.73

When traders use butterfly on SUPN

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

SUPN thesis for this butterfly

The market-implied 1-standard-deviation range for SUPN extends from approximately $41.01 on the downside to $51.67 on the upside. A SUPN long call butterfly is a pinning play: it pays maximum at the middle strike if SUPN settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SUPN IV rank near 5.31% 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 SUPN at 40.10%. As a Healthcare name, SUPN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SUPN-specific events.

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