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 OEF snapshot
As of May 15, 2026, spot at $369.88, ATM IV 17.00%, IV rank 39.22%, expected move 4.87%. The butterfly on OEF 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 OEF specifically: OEF IV at 17.00% 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 4.87% (roughly $18.03 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 OEF expiries trade a higher absolute premium for lower per-day decay. Position sizing on OEF should anchor to the underlying notional of $369.88 per share and to the trader's directional view on OEF etf.
OEF butterfly setup
The OEF 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 OEF near $369.88, the first option leg uses a $350.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed OEF 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 OEF shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $370.00 | $8.15 |
| Buy 1 | Call | $390.00 | $1.45 |

When traders use butterfly on OEF
Butterflies on OEF are pinning bets - traders use them when they expect OEF 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.
OEF thesis for this butterfly
The market-implied 1-standard-deviation range for OEF extends from approximately $351.85 on the downside to $387.91 on the upside. A OEF long call butterfly is a pinning play: it pays maximum at the middle strike if OEF settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current OEF IV rank near 39.22% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on OEF should anchor more to the directional view and the expected-move geometry. As a Financial Services name, OEF options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to OEF-specific events.
OEF 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. OEF positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move OEF alongside the broader basket even when OEF-specific fundamentals are unchanged. Always rebuild the position from current OEF chain quotes before placing a trade.
