TSBK (Timberland Bancorp, Inc.) trades in the Financial Services sector, specifically Banks - Regional, with a market capitalization of approximately $310.1M, a trailing P/E of 10.10, a beta of 0.31 versus the broader market, a 52-week range of 29.3-43.55, average daily share volume of 33K, a public-listing history dating back to 1998, approximately 274 full-time employees. These structural characteristics shape how TSBK stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.31 indicates TSBK 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 10.10 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. TSBK 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 TSBK?
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 TSBK snapshot
As of May 15, 2026, spot at $39.47, ATM IV 50.20%, IV rank 19.59%, expected move 14.39%. The cash-secured put on TSBK 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 TSBK specifically: TSBK IV at 50.20% is on the cheap side of its 1-year range, which means a premium-selling TSBK cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 14.39% (roughly $5.68 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 TSBK expiries trade a higher absolute premium for lower per-day decay. Position sizing on TSBK should anchor to the underlying notional of $39.47 per share and to the trader's directional view on TSBK stock.
TSBK cash-secured put setup
The TSBK 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 TSBK near $39.47, the first option leg uses a $37.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed TSBK 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 TSBK shares for the stock leg in covered calls and collars).

TSBK thesis for this cash-secured put
The market-implied 1-standard-deviation range for TSBK extends from approximately $33.79 on the downside to $45.15 on the upside. A TSBK cash-secured put lets a trader earn premium while waiting to acquire TSBK 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 TSBK IV rank near 19.59% 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 TSBK at 50.20%. As a Financial Services name, TSBK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to TSBK-specific events.
TSBK 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. TSBK positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move TSBK alongside the broader basket even when TSBK-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on TSBK carry tail risk when realized volatility exceeds the implied move; review historical TSBK earnings reactions and macro stress periods before sizing. Always rebuild the position from current TSBK chain quotes before placing a trade.
