What is a butterfly on SBSI?
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 SBSI snapshot
As of June 29, 2026, spot at $34.89, ATM IV 79.60%, IV rank 33.26%, expected move 22.82%. The butterfly on SBSI 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 18-day expiry.
Why this butterfly structure on SBSI specifically: SBSI IV at 79.60% 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 22.82% (roughly $7.96 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SBSI expiries trade a higher absolute premium for lower per-day decay. Position sizing on SBSI should anchor to the underlying notional of $34.89 per share and to the trader's directional view on SBSI stock.
SBSI butterfly setup
The SBSI 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 SBSI near $34.89, the first option leg uses a $33.15 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SBSI chain at a 18-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 SBSI shares for the stock leg in covered calls and collars).

SBSI thesis for this butterfly
The market-implied 1-standard-deviation range for SBSI extends from approximately $26.93 on the downside to $42.85 on the upside. A SBSI long call butterfly is a pinning play: it pays maximum at the middle strike if SBSI settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current SBSI IV rank near 33.26% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on SBSI should anchor more to the directional view and the expected-move geometry. As a Financial Services name, SBSI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SBSI-specific events.
SBSI 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. SBSI positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SBSI alongside the broader basket even when SBSI-specific fundamentals are unchanged. Always rebuild the position from current SBSI chain quotes before placing a trade.
