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 BUCK snapshot
As of May 15, 2026, spot at $23.50, ATM IV 42.10%, IV rank 30.20%, expected move 12.07%. The butterfly on BUCK 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 BUCK specifically: BUCK IV at 42.10% 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 12.07% (roughly $2.84 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 BUCK expiries trade a higher absolute premium for lower per-day decay. Position sizing on BUCK should anchor to the underlying notional of $23.50 per share and to the trader's directional view on BUCK etf.
BUCK butterfly setup
The BUCK 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 BUCK near $23.50, the first option leg uses a $22.33 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BUCK 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 BUCK shares for the stock leg in covered calls and collars).

BUCK thesis for this butterfly
The market-implied 1-standard-deviation range for BUCK extends from approximately $20.66 on the downside to $26.34 on the upside. A BUCK long call butterfly is a pinning play: it pays maximum at the middle strike if BUCK settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current BUCK IV rank near 30.20% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on BUCK should anchor more to the directional view and the expected-move geometry. As a Financial Services name, BUCK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BUCK-specific events.
BUCK 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. BUCK positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BUCK alongside the broader basket even when BUCK-specific fundamentals are unchanged. Always rebuild the position from current BUCK chain quotes before placing a trade.
