How DOCK iv/hv history Data Feeds Strategy Selection
Strategy selection on Corgi Etf Trust I - Portfolios Rail & Freight Etf 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 14.4% and dealer gamma exposure is negative, so dealer hedging amplifies directional moves. 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 DOCK IV vs HV chart
The dual-line chart below 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 14.4%, against 34.2% realized over the trailing 20 trading days. Implied is currently below realized by 19.8 vol points, an inverted regime where premium buyers are underpaying for the move - rare and often a setup for IV expansion. 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.
DOCK IV/HV regimes and trade selection
Using DOCK 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. Term structure is roughly flat at -0.015, no strong near vs far premium being priced. Pair the rank read with the slope read with the event calendar to choose the right tenor for the structure.
DOCK 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. The ratio of HV-20 (34.2%) to HV-60 (75.8%) 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 below to spot inflection points: meaningful IV/HV gap closures and openings tend to precede regime shifts by a few sessions.
