BMRC (Bank of Marin Bancorp) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $414.3M, a trailing P/E of 8.66, a beta of 0.81 versus the broader market, a 52-week range of 20.25-28.48, average daily share volume of 106K, a public-listing history dating back to 1999, approximately 291 full-time employees. These structural characteristics shape how BMRC stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.81 places BMRC roughly in line with broader market moves, so the strategy payoff and realized volatility track the index-equivalent baseline. The trailing P/E of 8.66 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. BMRC pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.
What is a cash-secured put on BMRC?
A cash-secured put sells an out-of-the-money put while holding cash equal to the strike-times-100 obligation, keeping the premium when the underlying stays above the strike.
Current BMRC snapshot
As of May 15, 2026, spot at $25.30, ATM IV 86.60%, IV rank 31.37%, expected move 24.83%. The cash-secured put on BMRC 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 cash-secured put structure on BMRC specifically: BMRC IV at 86.60% is mid-range versus its 1-year history, so the credit collected on a BMRC cash-secured put sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 24.83% (roughly $6.28 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 BMRC expiries trade a higher absolute premium for lower per-day decay. Position sizing on BMRC should anchor to the underlying notional of $25.30 per share and to the trader's directional view on BMRC stock.
BMRC cash-secured put setup
The BMRC cash-secured put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BMRC near $25.30, the first option leg uses a $24.04 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BMRC 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 BMRC shares for the stock leg in covered calls and collars).

BMRC thesis for this cash-secured put
The market-implied 1-standard-deviation range for BMRC extends from approximately $19.02 on the downside to $31.58 on the upside. A BMRC cash-secured put lets a trader earn premium while waiting to acquire BMRC at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current BMRC IV rank near 31.37% is mid-range against its 1-year distribution, so the IV signal is neutral; the cash-secured put thesis on BMRC should anchor more to the directional view and the expected-move geometry. As a Financial Services name, BMRC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BMRC-specific events.
BMRC cash-secured put positions are structurally neutral to slightly bullish; 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. BMRC positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BMRC alongside the broader basket even when BMRC-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on BMRC carry tail risk when realized volatility exceeds the implied move; review historical BMRC earnings reactions and macro stress periods before sizing. Always rebuild the position from current BMRC chain quotes before placing a trade.
