CDXS snapshot

As of August 14, 2026, spot at $1.58, ATM IV 272.50%, IV rank 63.92%, expected move 78.12%. The cash-secured put on CDXS 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 cash-secured put structure on CDXS specifically: CDXS IV at 272.50% is mid-range versus its 1-year history, so the credit collected on a CDXS cash-secured put sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 78.12% (roughly $1.23 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 CDXS expiries trade a higher absolute premium for lower per-day decay. Position sizing on CDXS should anchor to the underlying notional of $1.58 per share and to the trader's directional view on CDXS stock.

CDXS cash-secured put setup

The CDXS cash-secured 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 CDXS at $1.58 on that close, the first option leg uses a $1.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CDXS 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 CDXS shares for the stock leg in covered calls and collars).

CDXS thesis for this cash-secured put

The market-implied 1-standard-deviation range for CDXS extends from approximately $0.35 on the downside to $2.81 on the upside. A CDXS cash-secured put lets a trader earn premium while waiting to acquire CDXS at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current CDXS IV rank near 63.92% is mid-range against its 1-year distribution, so the IV signal is neutral; the cash-secured put thesis on CDXS should anchor more to the directional view and the expected-move geometry. As a Healthcare name, CDXS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CDXS-specific events.

CDXS cash-secured put positions are structurally neutral to slightly bullish; 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. CDXS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CDXS alongside the broader basket even when CDXS-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on CDXS carry tail risk when realized volatility exceeds the implied move; review historical CDXS earnings reactions and macro stress periods before sizing. Always rebuild the position from current CDXS chain quotes before placing a trade.
