Current CSBR snapshot
As of May 15, 2026, spot at $6.30, ATM IV 337.00%, IV rank 69.63%, expected move 96.61%. The cash-secured put on CSBR 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 CSBR specifically: CSBR IV at 337.00% is mid-range versus its 1-year history, so the credit collected on a CSBR cash-secured put sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 96.61% (roughly $6.09 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 CSBR expiries trade a higher absolute premium for lower per-day decay. Position sizing on CSBR should anchor to the underlying notional of $6.30 per share and to the trader's directional view on CSBR stock.
CSBR cash-secured put setup
The CSBR 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 CSBR near $6.30, the first option leg uses a $5.98 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CSBR 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 CSBR shares for the stock leg in covered calls and collars).

CSBR thesis for this cash-secured put
The market-implied 1-standard-deviation range for CSBR extends from approximately $0.21 on the downside to $12.39 on the upside. A CSBR cash-secured put lets a trader earn premium while waiting to acquire CSBR 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 CSBR IV rank near 69.63% is mid-range against its 1-year distribution, so the IV signal is neutral; the cash-secured put thesis on CSBR should anchor more to the directional view and the expected-move geometry. As a Healthcare name, CSBR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CSBR-specific events.
CSBR 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. CSBR positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CSBR alongside the broader basket even when CSBR-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on CSBR carry tail risk when realized volatility exceeds the implied move; review historical CSBR earnings reactions and macro stress periods before sizing. Always rebuild the position from current CSBR chain quotes before placing a trade.
