How ALGN iv/hv history Data Feeds Strategy Selection

Strategy selection on Align Technology, 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 55.6% 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 ALGN 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 55.6%, 59.0% IV rank, against 44.8% realized over the trailing 20 trading days. Implied is pricing above realized by 10.8 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.

ALGN IV/HV regimes and trade selection

ALGN IV rank at 59.0% sits mid-range - no structural edge from rank alone. Strategy choice should follow event calendar and the dealer-positioning read.

Using ALGN 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 -0.019, 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.

ALGN 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. ALGN's 59.0% IV rank places the ticker in the mid-range of its 1-year window - no strong cycle-position signal. The ratio of HV-20 (44.8%) to HV-60 (41.1%) 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.
