SJB snapshot
As of September 30, 2026, spot at $15.48, ATM IV 268.00%, IV rank 59.01%, expected move 76.83%. The butterfly on SJB below is built from the September 30, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 16-day expiry.
Why this butterfly structure on SJB specifically: SJB IV at 268.00% 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 76.83% (roughly $11.89 on the underlying). The 16-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SJB expiries trade a higher absolute premium for lower per-day decay. Position sizing on SJB should anchor to the underlying notional of $15.48 per share and to the trader's directional view on SJB etf.
SJB butterfly setup
The SJB butterfly below is built from the September 30, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SJB at $15.48 on that close, the first option leg uses a $15.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SJB chain at a 16-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 SJB shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $15.00 | $0.38 |
| Buy 1 | Call | $16.00 | $0.10 |

When traders use butterfly on SJB
Butterflies on SJB are pinning bets - traders use them when they expect SJB 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.
SJB thesis for this butterfly
The market-implied 1-standard-deviation range for SJB extends from approximately $3.59 on the downside to $27.37 on the upside. A SJB long call butterfly is a pinning play: it pays maximum at the middle strike if SJB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SJB IV rank near 59.01% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on SJB should anchor more to the directional view and the expected-move geometry. As a Financial Services name, SJB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SJB-specific events.
SJB 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. SJB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SJB alongside the broader basket even when SJB-specific fundamentals are unchanged. Always rebuild the position from current SJB chain quotes before placing a trade.
