What is a butterfly on DOCK?
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.
DOCK snapshot
As of September 29, 2026, spot at $25.13, ATM IV 18.50%, expected move 5.30%. The butterfly on DOCK below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 17-day expiry.
Why this butterfly structure on DOCK specifically: IV rank is unavailable in the current snapshot, so regime-based timing for DOCK is inferred from ATM IV at 18.50% alone, with a market-implied 1-standard-deviation move of approximately 5.30% (roughly $1.33 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated DOCK expiries trade a higher absolute premium for lower per-day decay. Position sizing on DOCK should anchor to the underlying notional of $25.13 per share and to the trader's directional view on DOCK etf.
DOCK butterfly setup
The DOCK 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 DOCK at $25.13 on that close, the first option leg uses a $23.87 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DOCK chain at a 17-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 DOCK shares for the stock leg in covered calls and collars).

|---|---|---|---|

| Buy 1 | Call | $26.39 | N/A |

DOCK thesis for this butterfly
The market-implied 1-standard-deviation range for DOCK extends from approximately $23.80 on the downside to $26.46 on the upside. A DOCK long call butterfly is a pinning play: it pays maximum at the middle strike if DOCK settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. As a Financial Services name, DOCK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DOCK-specific events.
DOCK 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. DOCK positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move DOCK alongside the broader basket even when DOCK-specific fundamentals are unchanged. Always rebuild the position from current DOCK chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on DOCK?
- A butterfly on DOCK is the butterfly strategy applied to DOCK (etf). The strategy is structurally neutral / pin (limited-risk, limited-reward): 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. With DOCK etf at $25.13 on the most recent close, the strikes shown on this page are snapped to the nearest listed DOCK chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are DOCK butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the DOCK butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 18.50%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a DOCK butterfly?
- The breakeven for the DOCK butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The DOCK market-implied 1-standard-deviation expected move in the same options snapshot is approximately 5.30%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
