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 CNTB snapshot
As of May 15, 2026, spot at $2.39, ATM IV 108.50%, IV rank 19.55%, expected move 31.11%. The cash-secured put on CNTB 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 CNTB specifically: CNTB IV at 108.50% is on the cheap side of its 1-year range, which means a premium-selling CNTB cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 31.11% (roughly $0.74 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 CNTB expiries trade a higher absolute premium for lower per-day decay. Position sizing on CNTB should anchor to the underlying notional of $2.39 per share and to the trader's directional view on CNTB stock.
CNTB cash-secured put setup
The CNTB 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 CNTB near $2.39, the first option leg uses a $2.27 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CNTB 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 CNTB shares for the stock leg in covered calls and collars).

CNTB thesis for this cash-secured put
The market-implied 1-standard-deviation range for CNTB extends from approximately $1.65 on the downside to $3.13 on the upside. A CNTB cash-secured put lets a trader earn premium while waiting to acquire CNTB 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 CNTB IV rank near 19.55% 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 CNTB at 108.50%. As a Healthcare name, CNTB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CNTB-specific events.
CNTB 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. CNTB positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CNTB alongside the broader basket even when CNTB-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on CNTB carry tail risk when realized volatility exceeds the implied move; review historical CNTB earnings reactions and macro stress periods before sizing. Always rebuild the position from current CNTB chain quotes before placing a trade.
