What is a butterfly on MMSI?
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 MMSI snapshot
As of May 15, 2026, spot at $61.30, ATM IV 35.40%, IV rank 5.03%, expected move 10.15%. The butterfly on MMSI 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 217-day expiry.
Why this butterfly structure on MMSI specifically: MMSI IV at 35.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a MMSI butterfly, with a market-implied 1-standard-deviation move of approximately 10.15% (roughly $6.22 on the underlying). The 217-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MMSI expiries trade a higher absolute premium for lower per-day decay. Position sizing on MMSI should anchor to the underlying notional of $61.30 per share and to the trader's directional view on MMSI stock.
MMSI butterfly setup
The MMSI 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 MMSI near $61.30, the first option leg uses a $60.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MMSI chain at a 217-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 MMSI shares for the stock leg in covered calls and collars).

| Buy 1 | Call | $60.00 | $8.75 |
| Sell 2 | Call | $60.00 | $8.75 |
| Buy 1 | Call | $65.00 | $6.05 |

When traders use butterfly on MMSI
Butterflies on MMSI are pinning bets - traders use them when they expect MMSI 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.
MMSI thesis for this butterfly
The market-implied 1-standard-deviation range for MMSI extends from approximately $55.08 on the downside to $67.52 on the upside. A MMSI long call butterfly is a pinning play: it pays maximum at the middle strike if MMSI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MMSI IV rank near 5.03% 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 MMSI at 35.40%. As a Healthcare name, MMSI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MMSI-specific events.
MMSI 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. MMSI positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MMSI alongside the broader basket even when MMSI-specific fundamentals are unchanged. Always rebuild the position from current MMSI chain quotes before placing a trade.
