CBIO snapshot
As of August 14, 2026, spot at $16.91, ATM IV 131.40%, IV rank 53.79%, expected move 37.67%. The long put on CBIO below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this long put structure on CBIO specifically: CBIO IV at 131.40% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 37.67% (roughly $6.37 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CBIO expiries trade a higher absolute premium for lower per-day decay. Position sizing on CBIO should anchor to the underlying notional of $16.91 per share and to the trader's directional view on CBIO stock.
CBIO long put setup
The CBIO long 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 CBIO at $16.91 on that close, the first option leg uses a $16.91 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CBIO chain at a 35-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 CBIO shares for the stock leg in covered calls and collars).

CBIO thesis for this long put
The market-implied 1-standard-deviation range for CBIO extends from approximately $10.54 on the downside to $23.28 on the upside. A CBIO long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long CBIO position with one put per 100 shares held. Current CBIO IV rank near 53.79% is mid-range against its 1-year distribution, so the IV signal is neutral; the long put thesis on CBIO should anchor more to the directional view and the expected-move geometry. As a Healthcare name, CBIO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CBIO-specific events.
CBIO long put positions are structurally bearish; 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. CBIO positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CBIO alongside the broader basket even when CBIO-specific fundamentals are unchanged. Long-premium structures like a long put on CBIO are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current CBIO chain quotes before placing a trade.
