What is a butterfly on MASS?
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 MASS snapshot
As of May 15, 2026, spot at $6.97, ATM IV 120.80%, IV rank 33.64%, expected move 34.63%. The butterfly on MASS 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 MASS specifically: MASS IV at 120.80% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 34.63% (roughly $2.41 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 MASS expiries trade a higher absolute premium for lower per-day decay. Position sizing on MASS should anchor to the underlying notional of $6.97 per share and to the trader's directional view on MASS stock.
MASS butterfly setup
The MASS 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 MASS near $6.97, the first option leg uses a $6.62 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MASS 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 MASS shares for the stock leg in covered calls and collars).

MASS thesis for this butterfly
The market-implied 1-standard-deviation range for MASS extends from approximately $4.56 on the downside to $9.38 on the upside. A MASS long call butterfly is a pinning play: it pays maximum at the middle strike if MASS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MASS IV rank near 33.64% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on MASS should anchor more to the directional view and the expected-move geometry. As a Healthcare name, MASS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MASS-specific events.
MASS 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. MASS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MASS alongside the broader basket even when MASS-specific fundamentals are unchanged. Always rebuild the position from current MASS chain quotes before placing a trade.
