OPBK (OP Bancorp) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $207.7M, a trailing P/E of 7.60, a beta of 0.62 versus the broader market, a 52-week range of 11.52-15.27, average daily share volume of 38K, a public-listing history dating back to 2005, approximately 231 full-time employees. These structural characteristics shape how OPBK stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.62 indicates OPBK has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 7.60 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. OPBK pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a butterfly on OPBK?
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 OPBK snapshot
As of May 15, 2026, spot at $13.63, ATM IV 70.50%, IV rank 12.79%, expected move 20.21%. The butterfly on OPBK 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 OPBK specifically: OPBK IV at 70.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a OPBK butterfly, with a market-implied 1-standard-deviation move of approximately 20.21% (roughly $2.75 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 OPBK expiries trade a higher absolute premium for lower per-day decay. Position sizing on OPBK should anchor to the underlying notional of $13.63 per share and to the trader's directional view on OPBK stock.
OPBK butterfly setup
The OPBK 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 OPBK near $13.63, the first option leg uses a $12.95 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed OPBK 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 OPBK shares for the stock leg in covered calls and collars).

OPBK thesis for this butterfly
The market-implied 1-standard-deviation range for OPBK extends from approximately $10.88 on the downside to $16.38 on the upside. A OPBK long call butterfly is a pinning play: it pays maximum at the middle strike if OPBK settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current OPBK IV rank near 12.79% 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 OPBK at 70.50%. As a Financial Services name, OPBK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to OPBK-specific events.
OPBK 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. OPBK positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move OPBK alongside the broader basket even when OPBK-specific fundamentals are unchanged. Always rebuild the position from current OPBK chain quotes before placing a trade.
