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 IAU snapshot
As of June 30, 2026, spot at $75.63, ATM IV 25.52%, IV rank 44.64%, expected move 7.32%. The butterfly on IAU 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 31-day expiry.
Why this butterfly structure on IAU specifically: IAU IV at 25.52% 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 7.32% (roughly $5.53 on the underlying). The 31-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated IAU expiries trade a higher absolute premium for lower per-day decay. Position sizing on IAU should anchor to the underlying notional of $75.63 per share and to the trader's directional view on IAU etf.
IAU butterfly setup
The IAU 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 IAU near $75.63, the first option leg uses a $72.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed IAU chain at a 31-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 IAU shares for the stock leg in covered calls and collars).

| Buy 1 | Call | $79.50 | $0.85 |

When traders use butterfly on IAU
Butterflies on IAU are pinning bets - traders use them when they expect IAU 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.
IAU thesis for this butterfly
The market-implied 1-standard-deviation range for IAU extends from approximately $70.10 on the downside to $81.16 on the upside. A IAU long call butterfly is a pinning play: it pays maximum at the middle strike if IAU settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current IAU IV rank near 44.64% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on IAU should anchor more to the directional view and the expected-move geometry. As a Financial Services name, IAU options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to IAU-specific events.
IAU 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. IAU positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move IAU alongside the broader basket even when IAU-specific fundamentals are unchanged. Always rebuild the position from current IAU chain quotes before placing a trade.
