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.
MGV snapshot
As of August 14, 2026, spot at $168.80, ATM IV 12.90%, IV rank 16.28%, expected move 3.70%. The butterfly on MGV 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 35-day expiry.
Why this butterfly structure on MGV specifically: MGV IV at 12.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a MGV butterfly, with a market-implied 1-standard-deviation move of approximately 3.70% (roughly $6.24 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MGV expiries trade a higher absolute premium for lower per-day decay. Position sizing on MGV should anchor to the underlying notional of $168.80 per share and to the trader's directional view on MGV etf.
MGV butterfly setup
The MGV 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 MGV at $168.80 on that close, the first option leg uses a $160.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MGV chain at a 35-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 MGV shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $169.00 | $2.93 |
| Buy 1 | Call | $175.00 | $0.81 |

When traders use butterfly on MGV
Butterflies on MGV are pinning bets - traders use them when they expect MGV 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.
MGV thesis for this butterfly
The market-implied 1-standard-deviation range for MGV extends from approximately $162.56 on the downside to $175.04 on the upside. A MGV long call butterfly is a pinning play: it pays maximum at the middle strike if MGV settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current MGV IV rank near 16.28% 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 MGV at 12.90%. As a Financial Services name, MGV options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MGV-specific events.
MGV 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. MGV positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MGV alongside the broader basket even when MGV-specific fundamentals are unchanged. Always rebuild the position from current MGV chain quotes before placing a trade.
