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.
MASS snapshot
As of August 14, 2026, spot at $10.13, ATM IV 72.50%, IV rank 17.46%, expected move 20.79%. The butterfly on MASS below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this butterfly structure on MASS specifically: MASS IV at 72.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a MASS butterfly, with a market-implied 1-standard-deviation move of approximately 20.79% (roughly $2.11 on the underlying). The 35-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 $10.13 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 at $10.13 on that close, the first option leg uses a $9.62 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 35-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).

|---|---|---|---|
| Buy 1 | Call | $9.62 | N/A |
| Sell 2 | Call | $10.13 | N/A |
| Buy 1 | Call | $10.64 | N/A |

When traders use butterfly on MASS
Butterflies on MASS are pinning bets - traders use them when they expect MASS 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.
MASS thesis for this butterfly
The market-implied 1-standard-deviation range for MASS extends from approximately $8.02 on the downside to $12.24 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 17.46% 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 MASS at 72.50%. 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.
Frequently asked questions
- What is a butterfly on MASS?
- A butterfly on MASS is the butterfly strategy applied to MASS (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 MASS stock at $10.13 on the most recent close, the strikes shown on this page are snapped to the nearest listed MASS chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are MASS 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 MASS butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 72.50%), 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 MASS butterfly?
- The breakeven for the MASS butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The MASS market-implied 1-standard-deviation expected move in the same options snapshot is approximately 20.79%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on MASS?
- Butterflies on MASS are pinning bets - traders use them when they expect MASS 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.
- How does current MASS implied volatility affect this butterfly?
- MASS ATM IV is at 72.50% with IV rank near 17.46%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
