What is a butterfly on ZNTL?
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 ZNTL snapshot
As of May 15, 2026, spot at $4.04, ATM IV 161.00%, IV rank 40.03%, expected move 46.16%. The butterfly on ZNTL 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 ZNTL specifically: ZNTL IV at 161.00% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 46.16% (roughly $1.86 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 ZNTL expiries trade a higher absolute premium for lower per-day decay. Position sizing on ZNTL should anchor to the underlying notional of $4.04 per share and to the trader's directional view on ZNTL stock.
ZNTL butterfly setup
The ZNTL 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 ZNTL near $4.04, the first option leg uses a $3.84 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ZNTL 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 ZNTL shares for the stock leg in covered calls and collars).

When traders use butterfly on ZNTL
Butterflies on ZNTL are pinning bets - traders use them when they expect ZNTL 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.
ZNTL thesis for this butterfly
The market-implied 1-standard-deviation range for ZNTL extends from approximately $2.18 on the downside to $5.90 on the upside. A ZNTL long call butterfly is a pinning play: it pays maximum at the middle strike if ZNTL settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ZNTL IV rank near 40.03% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on ZNTL should anchor more to the directional view and the expected-move geometry. As a Healthcare name, ZNTL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ZNTL-specific events.
ZNTL 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. ZNTL positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ZNTL alongside the broader basket even when ZNTL-specific fundamentals are unchanged. Always rebuild the position from current ZNTL chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on ZNTL?
- A butterfly on ZNTL is the butterfly strategy applied to ZNTL (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 ZNTL stock trading near $4.04, the strikes shown on this page are snapped to the nearest listed ZNTL chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are ZNTL 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 ZNTL butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 161.00%), 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 ZNTL butterfly?
- The breakeven for the ZNTL 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 ZNTL market-implied 1-standard-deviation expected move is approximately 46.16%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
