Current CERS snapshot
As of May 15, 2026, spot at $2.37, ATM IV 108.70%, IV rank 18.47%, expected move 31.16%. The long put on CERS 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 long put structure on CERS specifically: CERS IV at 108.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a CERS long put, with a market-implied 1-standard-deviation move of approximately 31.16% (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 CERS expiries trade a higher absolute premium for lower per-day decay. Position sizing on CERS should anchor to the underlying notional of $2.37 per share and to the trader's directional view on CERS stock.
CERS long put setup
The CERS 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 CERS near $2.37, the first option leg uses a $2.37 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CERS 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 CERS shares for the stock leg in covered calls and collars).

CERS thesis for this long put
The market-implied 1-standard-deviation range for CERS extends from approximately $1.63 on the downside to $3.11 on the upside. A CERS long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long CERS position with one put per 100 shares held. Current CERS IV rank near 18.47% 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 CERS at 108.70%. As a Healthcare name, CERS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CERS-specific events.
CERS 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. CERS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CERS alongside the broader basket even when CERS-specific fundamentals are unchanged. Long-premium structures like a long put on CERS 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 CERS chain quotes before placing a trade.
