What is a butterfly on BLCK?
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.
BLCK snapshot
As of September 29, 2026, spot at $23.88, ATM IV 64.00%, expected move 18.35%. The butterfly on BLCK 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 BLCK specifically: IV rank is unavailable in the current snapshot, so regime-based timing for BLCK is inferred from ATM IV at 64.00% alone, with a market-implied 1-standard-deviation move of approximately 18.35% (roughly $4.38 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 BLCK expiries trade a higher absolute premium for lower per-day decay. Position sizing on BLCK should anchor to the underlying notional of $23.88 per share and to the trader's directional view on BLCK stock.
BLCK butterfly setup
The BLCK 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 BLCK at $23.88 on that close, the first option leg uses a $22.69 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BLCK 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 BLCK shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $22.69 | N/A |
| Sell 2 | Call | $23.88 | N/A |
| Buy 1 | Call | $25.07 | N/A |

BLCK thesis for this butterfly
The market-implied 1-standard-deviation range for BLCK extends from approximately $19.50 on the downside to $28.26 on the upside. A BLCK long call butterfly is a pinning play: it pays maximum at the middle strike if BLCK 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, BLCK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BLCK-specific events.
BLCK 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. BLCK positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BLCK alongside the broader basket even when BLCK-specific fundamentals are unchanged. Always rebuild the position from current BLCK chain quotes before placing a trade.

With BLCK stock at $23.88 on the most recent close, the strikes shown on this page are snapped to the nearest listed BLCK chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are BLCK butterfly max profit and max loss calculated?
