RBB (RBB Bancorp) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $396.8M, a trailing P/E of 9.68, a beta of 1.06 versus the broader market, a 52-week range of 15.945-24.73, average daily share volume of 79K, a public-listing history dating back to 2017, approximately 372 full-time employees. These structural characteristics shape how RBB stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 1.06 places RBB roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 9.68 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. RBB pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a butterfly on RBB?
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 RBB snapshot
As of May 15, 2026, spot at $22.95, ATM IV 29.60%, IV rank 12.24%, expected move 8.49%. The butterfly on RBB 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 RBB specifically: RBB IV at 29.60% is on the cheap side of its 1-year range, which favors premium-buying structures like a RBB butterfly, with a market-implied 1-standard-deviation move of approximately 8.49% (roughly $1.95 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 RBB expiries trade a higher absolute premium for lower per-day decay. Position sizing on RBB should anchor to the underlying notional of $22.95 per share and to the trader's directional view on RBB stock.
RBB butterfly setup
The RBB 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 RBB near $22.95, the first option leg uses a $21.80 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RBB 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 RBB shares for the stock leg in covered calls and collars).

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

| Buy 1 | Call | $24.10 | N/A |

When traders use butterfly on RBB

RBB thesis for this butterfly
The market-implied 1-standard-deviation range for RBB extends from approximately $21.00 on the downside to $24.90 on the upside. A RBB long call butterfly is a pinning play: it pays maximum at the middle strike if RBB settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current RBB IV rank near 12.24% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on RBB at 29.60%. As a Financial Services name, RBB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RBB-specific events.
RBB 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. RBB positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RBB alongside the broader basket even when RBB-specific fundamentals are unchanged. Always rebuild the position from current RBB chain quotes before placing a trade.
