What is a butterfly on STXS?
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 STXS snapshot
As of May 15, 2026, spot at $1.88, ATM IV 358.80%, IV rank 100.00%, expected move 102.87%. The butterfly on STXS 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 STXS specifically: STXS IV at 358.80% is rich versus its 1-year range, which makes a premium-buying STXS butterfly relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 102.87% (roughly $1.93 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 STXS expiries trade a higher absolute premium for lower per-day decay. Position sizing on STXS should anchor to the underlying notional of $1.88 per share and to the trader's directional view on STXS stock.
STXS butterfly setup
The STXS 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 STXS near $1.88, the first option leg uses a $1.79 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STXS 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 STXS shares for the stock leg in covered calls and collars).

|---|---|---|---|

| Buy 1 | Call | $1.97 | N/A |

When traders use butterfly on STXS
Butterflies on STXS are pinning bets - traders use them when they expect STXS 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.
STXS thesis for this butterfly
The market-implied 1-standard-deviation range for STXS extends from approximately $-0.05 on the downside to $3.81 on the upside. A STXS long call butterfly is a pinning play: it pays maximum at the middle strike if STXS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current STXS IV rank near 100.00% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on STXS at 358.80%. As a Healthcare name, STXS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STXS-specific events.
STXS 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. STXS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STXS alongside the broader basket even when STXS-specific fundamentals are unchanged. Always rebuild the position from current STXS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on STXS?
- A butterfly on STXS is the butterfly strategy applied to STXS (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): 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. With STXS stock trading near $1.88, the strikes shown on this page are snapped to the nearest listed STXS chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are STXS 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 STXS butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 358.80%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a STXS butterfly?
- The breakeven for the STXS butterfly priced on this page is no defined breakeven on the modeled curve 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 STXS market-implied 1-standard-deviation expected move is approximately 102.87%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on STXS?

- How does current STXS implied volatility affect this butterfly?
- STXS ATM IV is at 358.80% with IV rank near 100.00%, which is elevated relative to its 1-year range.
