What is a butterfly on MLYS?
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.
MLYS snapshot
As of August 14, 2026, spot at $25.69, ATM IV 54.20%, IV rank 6.84%, expected move 15.54%. The butterfly on MLYS 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 MLYS specifically: MLYS IV at 54.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a MLYS butterfly, with a market-implied 1-standard-deviation move of approximately 15.54% (roughly $3.99 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 MLYS expiries trade a higher absolute premium for lower per-day decay. Position sizing on MLYS should anchor to the underlying notional of $25.69 per share and to the trader's directional view on MLYS stock.
MLYS butterfly setup
The MLYS 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 MLYS at $25.69 on that close, the first option leg uses a $24.41 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MLYS 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 MLYS shares for the stock leg in covered calls and collars).

When traders use butterfly on MLYS
Butterflies on MLYS are pinning bets - traders use them when they expect MLYS 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.
MLYS thesis for this butterfly
The market-implied 1-standard-deviation range for MLYS extends from approximately $21.70 on the downside to $29.68 on the upside. A MLYS long call butterfly is a pinning play: it pays maximum at the middle strike if MLYS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MLYS IV rank near 6.84% 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 MLYS at 54.20%. As a Healthcare name, MLYS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MLYS-specific events.
MLYS 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. MLYS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MLYS alongside the broader basket even when MLYS-specific fundamentals are unchanged. Always rebuild the position from current MLYS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on MLYS?
- A butterfly on MLYS is the butterfly strategy applied to MLYS (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 MLYS stock at $25.69 on the most recent close, the strikes shown on this page are snapped to the nearest listed MLYS chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are MLYS 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 MLYS butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 54.20%), 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 MLYS butterfly?
- The breakeven for the MLYS 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 MLYS market-implied 1-standard-deviation expected move in the same options snapshot is approximately 15.54%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
