What is the CRDF variance risk premium?

The variance risk premium is the persistent gap between implied and subsequently realized volatility. In equity markets it averages positive because option sellers demand compensation for bearing variance shocks.

What does CRDF IV rank mean for strategy selection?

IV rank normalizes the current ATM IV to its 1-year range: 0% is the low, 100% is the high. CRDF's current rank of 44.3% signals where current pricing sits in its own 1-year history. High-rank regimes typically favor premium-selling structures (credit spreads, condors, covered calls); low-rank regimes typically favor premium-buying or long-volatility structures.

How CRDF iv/hv history Data Feeds Strategy Selection

Strategy selection on Cardiff Oncology, Inc. options does not derive from any single metric in isolation. The iv/hv history view above sits inside a broader read: ATM IV currently sits at 223.3% and dealer gamma exposure is positive, so dealer hedging is mechanically mean-reverting. Combine the iv/hv history 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 CRDF IV vs HV chart

The dual-line chart above tracks ATM implied volatility (forward-looking, what the chain is pricing) against 20-day realized historical volatility (backward-looking, what actually happened). ATM IV currently prints at 223.3%, 44.3% IV rank, against 51.7% realized over the trailing 20 trading days. Implied is pricing above realized by 171.6 vol points, the typical variance-risk-premium positive state in which premium sellers earn the gap. Persistent IV-above-HV is the variance-risk-premium-positive state typical of equity markets; persistent IV-below-HV is rare and usually marks underpriced vol that often expands.

CRDF IV/HV regimes and trade selection

CRDF IV rank at 44.3% sits mid-range - no structural edge from rank alone. Strategy choice should follow event calendar and the dealer-positioning read.

Using CRDF vol history alongside the term structure

The IV/HV gap on this page captures the level of premium; the term-structure slope on the volatility page captures its shape across expirations. Contango (positive slope 1.723) is the resting state - longer-dated IV trades above near-dated IV because long-dated cycles include uncertain macro states. Pair the rank read with the slope read with the event calendar to choose the right tenor for the structure.

CRDF IV/HV signal in volatility-cycle context

Equity-vol cycles tend to compress and expand on multi-month timeframes: a typical sequence runs low-IV-rank consolidation (months of flat tape, decaying premium) into a vol-expansion catalyst (earnings miss, macro shock, regime change) into elevated-IV-rank stress (premiums fat, dispersion high) back to mean-reverting compression. CRDF's 44.3% IV rank places the ticker in the mid-range of its 1-year window - no strong cycle-position signal. The ratio of HV-20 (51.7%) to HV-60 (118.6%) gives a second cycle indicator: when 20-day exceeds 60-day, recent realization is running hotter than the trailing-quarter average - typically a sign that recent days have already started expanding vol regardless of where IV rank prints. Use the time series above to spot inflection points: meaningful IV/HV gap closures and openings tend to precede regime shifts by a few sessions.
