How SNOW iv/hv history Data Feeds Strategy Selection
Strategy selection on Snowflake 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 59.6% 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 SNOW 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 59.6%, 51.7% IV rank, against 118.1% realized over the trailing 20 trading days. Implied is currently below realized by 58.5 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.
SNOW IV/HV regimes and trade selection
SNOW IV rank at 51.7% sits mid-range - no structural edge from rank alone. Strategy choice should follow event calendar and the dealer-positioning read.
Using SNOW 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 -0.013, 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.
SNOW 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. SNOW's 51.7% IV rank places the ticker in the mid-range of its 1-year window - no strong cycle-position signal. The ratio of HV-20 (118.1%) to HV-60 (88.1%) 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.

Daily ATM implied volatility and 20-day realized (historical) volatility for SNOW over the last ~40 trading days. The IV-HV gap measures the variance risk premium - when IV trades persistently above realized HV, premium-sellers earn the spread; when IV dips below HV, vol is structurally underpriced.

Frequently asked SNOW iv/hv history questions
- Is SNOW options pricing rich or cheap right now?
- As of May 28, 2026, Snowflake Inc. (SNOW) ATM IV is 59.6% against 20-day realized volatility of 118.1%. IV rank is 51.7%. Realized volatility currently exceeds implied: an inversion of the typical equity volatility risk premium that often precedes IV expansion.
- What is the SNOW 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. SNOW is currently pricing inverted to the historical pattern, which is one input to whether short-vol or long-vol structures carry their typical edge.
- What does SNOW 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. SNOW's current rank of 51.7% 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.
