CDNL snapshot
As of August 14, 2026, spot at $38.91, ATM IV 86.10%, expected move 24.68%. The bear put spread on CDNL 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 bear put spread structure on CDNL specifically: IV rank is unavailable in the current snapshot, so regime-based timing for CDNL is inferred from ATM IV at 86.10% alone, with a market-implied 1-standard-deviation move of approximately 24.68% (roughly $9.60 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 CDNL expiries trade a higher absolute premium for lower per-day decay. Position sizing on CDNL should anchor to the underlying notional of $38.91 per share and to the trader's directional view on CDNL stock.
CDNL bear put spread setup
The CDNL 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 CDNL at $38.91 on that close, the first option leg uses a $38.91 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CDNL 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 CDNL shares for the stock leg in covered calls and collars).

CDNL thesis for this bear put spread
The market-implied 1-standard-deviation range for CDNL extends from approximately $29.31 on the downside to $48.51 on the upside. A CDNL bear put spread caps both the risk and the reward of a bearish position; relative to an outright long put on CDNL, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. As a Industrials name, CDNL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CDNL-specific events.
CDNL 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. CDNL positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CDNL alongside the broader basket even when CDNL-specific fundamentals are unchanged. Long-premium structures like a bear put spread on CDNL 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.
