How CDNA options chain Data Feeds Strategy Selection

Strategy selection on CareDx, Inc options does not derive from any single metric in isolation. The options chain view above sits inside a broader read: ATM IV currently sits at 82.9% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. Combine the options chain data here with the volatility-skew surface, dealer-gamma exposure, max-pain level, and upcoming-events calendar to build a positioning thesis. Risk-defined structures (credit spreads, debit spreads, iron condors) are usually safer than naked positions while the regime is uncertain; the data on this page anchors the inputs but does not by itself constitute a trade thesis.

How to read the CDNA chain depth

The listed-expirations table above shows every expiration available for CareDx, Inc options with its days-to-expiration count and ATM implied volatility. Front-month expirations carry the most volume, the highest gamma, and the tightest bid-ask spreads; longer-dated tenors carry less liquidity but more vega exposure. CDNA front expiration sits at 18 days - the typical hedging horizon for monthly options. The backwardated slope of -0.023 means near-dated IV is pricing acute event risk.

CDNA chain mechanics and execution

Options are listed at standardized strike intervals (typically $1 for sub-$25 underlyings, $2.50-$5 for mid-cap, $10-$50 for large-cap), and the deltas of each listed strike are determined by where IV lies relative to the strike's moneyness. Average bid/ask spread on the CDNA chain is 62.89% - a measure of liquidity. Tighter spreads on liquid strikes mean lower transaction costs; wider spreads on long-dated or far-OTM strikes mean execution drag can dominate the math. The chain table on the SPA side shows the full per-strike, per-expiration grid; this SSR page summarizes the listed expirations and the front-month context to anchor the structural read.

Using the CDNA chain to build structures

Strategy selection starts with the chain: directional theses use single-leg calls or puts, range-bound theses use credit spreads or iron condors, vol theses use straddles or strangles, calendar theses use diagonal spreads. CDNA's current 23.77% expected move anchors wing placement - structures with wings at the implied band collect the modal-outcome premium under lognormal assumptions. Cross-reference with the gamma-exposure profile to understand where dealer hedging will reinforce or fight your position, and with the volatility-skew chart to confirm the strikes you're trading sit at the IV levels your strategy assumes.
