What is a long put on CMPX?
A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.
Current CMPX snapshot
As of May 15, 2026, spot at $1.90, ATM IV 51.40%, IV rank 6.75%, expected move 14.74%. The long put on CMPX 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 CMPX specifically: CMPX IV at 51.40% is on the cheap side of its 1-year range, which favors premium-buying structures like a CMPX long put, with a market-implied 1-standard-deviation move of approximately 14.74% (roughly $0.28 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 CMPX expiries trade a higher absolute premium for lower per-day decay. Position sizing on CMPX should anchor to the underlying notional of $1.90 per share and to the trader's directional view on CMPX stock.
CMPX long put setup
The CMPX 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 CMPX near $1.90, the first option leg uses a $1.90 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CMPX 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 CMPX shares for the stock leg in covered calls and collars).

CMPX thesis for this long put
The market-implied 1-standard-deviation range for CMPX extends from approximately $1.62 on the downside to $2.18 on the upside. A CMPX long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long CMPX position with one put per 100 shares held. Current CMPX IV rank near 6.75% 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 CMPX at 51.40%. As a Healthcare name, CMPX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CMPX-specific events.
CMPX 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. CMPX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CMPX alongside the broader basket even when CMPX-specific fundamentals are unchanged. Long-premium structures like a long put on CMPX 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 CMPX chain quotes before placing a trade.
