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 VWOB snapshot
As of May 15, 2026, spot at $66.16, ATM IV 4.80%, IV rank 0.15%, expected move 1.38%. The butterfly on VWOB 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 VWOB specifically: VWOB IV at 4.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a VWOB butterfly, with a market-implied 1-standard-deviation move of approximately 1.38% (roughly $0.91 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 VWOB expiries trade a higher absolute premium for lower per-day decay. Position sizing on VWOB should anchor to the underlying notional of $66.16 per share and to the trader's directional view on VWOB etf.
VWOB butterfly setup
The VWOB 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 VWOB near $66.16, the first option leg uses a $62.85 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed VWOB 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 VWOB shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $62.85 | N/A |
| Sell 2 | Call | $66.16 | N/A |
| Buy 1 | Call | $69.47 | N/A |

VWOB thesis for this butterfly
The market-implied 1-standard-deviation range for VWOB extends from approximately $65.25 on the downside to $67.07 on the upside. A VWOB long call butterfly is a pinning play: it pays maximum at the middle strike if VWOB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current VWOB IV rank near 0.15% 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 VWOB at 4.80%. As a Financial Services name, VWOB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to VWOB-specific events.
VWOB 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. VWOB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move VWOB alongside the broader basket even when VWOB-specific fundamentals are unchanged. Always rebuild the position from current VWOB chain quotes before placing a trade.
