Current UNG snapshot
As of May 15, 2026, spot at $11.32, ATM IV 46.86%, IV rank 6.49%, expected move 13.43%. The butterfly on UNG 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 UNG specifically: UNG IV at 46.86% is on the cheap side of its 1-year range, which favors premium-buying structures like a UNG butterfly, with a market-implied 1-standard-deviation move of approximately 13.43% (roughly $1.52 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 UNG expiries trade a higher absolute premium for lower per-day decay. Position sizing on UNG should anchor to the underlying notional of $11.32 per share and to the trader's directional view on UNG etf.
UNG butterfly setup
The UNG 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 UNG near $11.32, the first option leg uses a $11.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed UNG 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 UNG shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $11.50 | $0.50 |
| Buy 1 | Call | $12.00 | $0.35 |

When traders use butterfly on UNG
Butterflies on UNG are pinning bets - traders use them when they expect UNG 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.
UNG thesis for this butterfly
The market-implied 1-standard-deviation range for UNG extends from approximately $9.80 on the downside to $12.84 on the upside. A UNG long call butterfly is a pinning play: it pays maximum at the middle strike if UNG settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current UNG IV rank near 6.49% 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 UNG at 46.86%. As a Financial Services name, UNG options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to UNG-specific events.
UNG 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. UNG positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move UNG alongside the broader basket even when UNG-specific fundamentals are unchanged. Always rebuild the position from current UNG chain quotes before placing a trade.
