VOO snapshot
As of August 14, 2026, spot at $713.41, ATM IV 12.20%, IV rank 9.54%, expected move 3.50%. The butterfly on VOO below is built from the August 14, 2026 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 VOO specifically: VOO IV at 12.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a VOO butterfly, with a market-implied 1-standard-deviation move of approximately 3.50% (roughly $24.95 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 VOO expiries trade a higher absolute premium for lower per-day decay. Position sizing on VOO should anchor to the underlying notional of $713.41 per share and to the trader's directional view on VOO etf.
VOO butterfly setup
The VOO butterfly below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With VOO at $713.41 on that close, the first option leg uses a $677.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed VOO 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 VOO shares for the stock leg in covered calls and collars).

When traders use butterfly on VOO
Butterflies on VOO are pinning bets - traders use them when they expect VOO 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.
VOO thesis for this butterfly
The market-implied 1-standard-deviation range for VOO extends from approximately $688.46 on the downside to $738.36 on the upside. A VOO long call butterfly is a pinning play: it pays maximum at the middle strike if VOO settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current VOO IV rank near 9.54% 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 VOO at 12.20%. As a Financial Services name, VOO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to VOO-specific events.
VOO 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. VOO positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move VOO alongside the broader basket even when VOO-specific fundamentals are unchanged. Always rebuild the position from current VOO chain quotes before placing a trade.
