What is a butterfly on EVMN?
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 EVMN snapshot
As of May 15, 2026, spot at $22.75, ATM IV 119.20%, expected move 34.17%. The butterfly on EVMN 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 EVMN specifically: IV rank is unavailable in the current snapshot, so regime-based timing for EVMN is inferred from ATM IV at 119.20% alone, with a market-implied 1-standard-deviation move of approximately 34.17% (roughly $7.77 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 EVMN expiries trade a higher absolute premium for lower per-day decay. Position sizing on EVMN should anchor to the underlying notional of $22.75 per share and to the trader's directional view on EVMN stock.
EVMN butterfly setup
The EVMN 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 EVMN near $22.75, the first option leg uses a $21.61 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed EVMN 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 EVMN shares for the stock leg in covered calls and collars).

EVMN thesis for this butterfly
The market-implied 1-standard-deviation range for EVMN extends from approximately $14.98 on the downside to $30.52 on the upside. A EVMN long call butterfly is a pinning play: it pays maximum at the middle strike if EVMN settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Healthcare name, EVMN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to EVMN-specific events.
EVMN 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. EVMN positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move EVMN alongside the broader basket even when EVMN-specific fundamentals are unchanged. Always rebuild the position from current EVMN chain quotes before placing a trade.
