CLDX bear put spread setup

The CLDX bear put spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CLDX near $31.31, the first option leg uses a $31.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CLDX 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 CLDX shares for the stock leg in covered calls and collars).

CLDX thesis for this bear put spread

The market-implied 1-standard-deviation range for CLDX extends from approximately $27.53 on the downside to $35.09 on the upside. A CLDX bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on CLDX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current CLDX IV rank near 3.82% 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 CLDX at 42.10%. As a Healthcare name, CLDX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CLDX-specific events.

CLDX bear put spread positions are structurally moderately 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. CLDX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CLDX alongside the broader basket even when CLDX-specific fundamentals are unchanged. Long-premium structures like a bear put spread on CLDX 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 CLDX chain quotes before placing a trade.
