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 ZSL snapshot
As of May 15, 2026, spot at $19.72, ATM IV 104.61%, IV rank 39.23%, expected move 29.99%. The butterfly on ZSL 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 28-day expiry.
Why this butterfly structure on ZSL specifically: ZSL IV at 104.61% 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 29.99% (roughly $5.91 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ZSL expiries trade a higher absolute premium for lower per-day decay. Position sizing on ZSL should anchor to the underlying notional of $19.72 per share and to the trader's directional view on ZSL etf.
ZSL butterfly setup
The ZSL 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 ZSL near $19.72, the first option leg uses a $18.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ZSL chain at a 28-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 ZSL shares for the stock leg in covered calls and collars).

| Buy 1 | Call | $18.50 | $2.70 |
| Sell 2 | Call | $19.50 | $1.73 |
| Buy 1 | Call | $20.50 | $1.88 |

When traders use butterfly on ZSL
Butterflies on ZSL are pinning bets - traders use them when they expect ZSL 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.
ZSL thesis for this butterfly
The market-implied 1-standard-deviation range for ZSL extends from approximately $13.81 on the downside to $25.63 on the upside. A ZSL long call butterfly is a pinning play: it pays maximum at the middle strike if ZSL settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ZSL IV rank near 39.23% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on ZSL should anchor more to the directional view and the expected-move geometry. As a Financial Services name, ZSL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ZSL-specific events.
ZSL 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. ZSL positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ZSL alongside the broader basket even when ZSL-specific fundamentals are unchanged. Always rebuild the position from current ZSL chain quotes before placing a trade.
