Methodology
Data source: ORATS, the institutional options data provider that powers all ApexVol analytics. The universe is the full ORATS US equity coverage filtered to liquid optionable names: share price above $5, a 20-day average options volume of at least 1,000 contracts, and valid implied volatility data — 1159 stocks for June 2026. IV rank (1-year IV percentile) measures where a stock's current 30-day implied volatility sits relative to its own range over the past 252 trading days: 100 means IV is at a 1-year high, 0 means a 1-year low. IV-vs-HV spreads compare 30-day implied volatility against 20-day realized (historical) volatility; implied earnings moves are derived from ORATS earnings-dated straddle pricing. Statistics are computed once at the start of the month and are not updated intraday.
