What is a butterfly on MENS?
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.
MENS snapshot
As of August 14, 2026, spot at $2.04, ATM IV 17.80%, IV rank 0.10%, expected move 5.10%. The butterfly on MENS 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 MENS specifically: MENS IV at 17.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a MENS butterfly, with a market-implied 1-standard-deviation move of approximately 5.10% (roughly $0.10 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 MENS expiries trade a higher absolute premium for lower per-day decay. Position sizing on MENS should anchor to the underlying notional of $2.04 per share and to the trader's directional view on MENS stock.
MENS butterfly setup
The MENS 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 MENS at $2.04 on that close, the first option leg uses a $1.94 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MENS 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 MENS shares for the stock leg in covered calls and collars).

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

| Buy 1 | Call | $2.14 | N/A |

When traders use butterfly on MENS
Butterflies on MENS are pinning bets - traders use them when they expect MENS 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.
MENS thesis for this butterfly
The market-implied 1-standard-deviation range for MENS extends from approximately $1.94 on the downside to $2.14 on the upside. A MENS long call butterfly is a pinning play: it pays maximum at the middle strike if MENS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MENS IV rank near 0.10% 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 MENS at 17.80%. As a Healthcare name, MENS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MENS-specific events.
MENS 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. MENS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MENS alongside the broader basket even when MENS-specific fundamentals are unchanged. Always rebuild the position from current MENS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on MENS?
- A butterfly on MENS is the butterfly strategy applied to MENS (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 MENS stock at $2.04 on the most recent close, the strikes shown on this page are snapped to the nearest listed MENS chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are MENS 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 MENS butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 17.80%), 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 MENS butterfly?
