What is a butterfly on ZYME?

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 ZYME snapshot

As of May 15, 2026, spot at $23.70, ATM IV 43.70%, IV rank 2.60%, expected move 12.53%. The butterfly on ZYME 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 ZYME specifically: ZYME IV at 43.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a ZYME butterfly, with a market-implied 1-standard-deviation move of approximately 12.53% (roughly $2.97 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 ZYME expiries trade a higher absolute premium for lower per-day decay. Position sizing on ZYME should anchor to the underlying notional of $23.70 per share and to the trader's directional view on ZYME stock.

ZYME butterfly setup

The ZYME 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 ZYME near $23.70, the first option leg uses a $22.51 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ZYME 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 ZYME shares for the stock leg in covered calls and collars).

When traders use butterfly on ZYME

Butterflies on ZYME are pinning bets - traders use them when they expect ZYME 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.

ZYME thesis for this butterfly

The market-implied 1-standard-deviation range for ZYME extends from approximately $20.73 on the downside to $26.67 on the upside. A ZYME long call butterfly is a pinning play: it pays maximum at the middle strike if ZYME settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ZYME IV rank near 2.60% 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 ZYME at 43.70%. As a Healthcare name, ZYME options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ZYME-specific events.

ZYME 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. ZYME positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ZYME alongside the broader basket even when ZYME-specific fundamentals are unchanged. Always rebuild the position from current ZYME chain quotes before placing a trade.

How are ZYME butterfly max profit and max loss calculated?

What is the breakeven for a ZYME butterfly?
The breakeven for the ZYME butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current ZYME market-implied 1-standard-deviation expected move is approximately 12.53%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
