IV Rank, IV Percentile, IV-HV Spread Screener

How to Use the IV Rank Screener ▶ Show Guide

This implied volatility screener ranks over 2,500 optionable stocks by IV Rank and IV Percentile, comparing current implied volatility to the 52-week range. Use it to find high IV rank stocks for premium selling strategies like iron condors and credit spreads, or low IV rank stocks where options are historically cheap for directional plays. The IV-HV spread column highlights where implied volatility diverges from actual stock movement.

• IV Rank measures where current IV sits within the 52-week high–low range on a scale of 0–100. A rank of 80 means current IV is near the top of its annual range — options premiums are relatively expensive, favoring premium selling strategies like iron condors and credit spreads. A rank of 20 means IV is near the bottom — options are historically cheap, making it a better time to buy options for directional plays or LEAPS.
• IV Percentile shows the percentage of trading days in the past year where IV was below today’s level. An IV Percentile of 80 means IV was lower than today on 80% of trading days — current premiums are unusually rich. Many traders prefer IV Percentile over IV Rank because it’s less distorted by a single extreme spike — if a stock had one massive IV event months ago, IV Rank can stay suppressed even when IV is elevated compared to most days. IV Percentile captures that nuance.
• IV–HV Spread shows the gap between current implied volatility and 100-day historical (realized) volatility. Positive values mean options are priced above actual stock movement — potential premium selling edge. Negative values mean options are cheap relative to how much the stock has actually been moving. The 100-day HV window smooths out short-term noise better than shorter lookbacks.
• IV Chg 1d / 5d shows the change in implied volatility over the last 1 and 5 trading days. Green (+) means IV is rising — increasing option premiums and potential mean-reversion selling setups. Red (−) means IV is contracting — cheaper premiums and potential buying opportunities.
• IV Z-Score measures how many standard deviations current IV is from the 252-day mean. Values ≥ 2.0 signal statistically high IV (premium selling sweet spot). Values ≤ −2.0 signal unusually low IV (cheap options for directional bets or LEAPS).
• IV Mean Ratio compares the 126-day (6-month) average IV to the 252-day (1-year) average. Values > 1.0 mean the recent vol regime is elevated vs. the annual norm — a potential vol expansion. Values < 1.0 indicate vol compression, where IV may be due for a move higher.
• HV Rank measures where the stock’s current 50-day realized (historical) volatility sits within its 252-day range (0–100). Compare it to IV Rank to gauge if options are fairly priced: when IV Rank is high but HV Rank is low, options may be overpriced relative to actual stock movement — a premium selling signal. When both are high, the stock is genuinely volatile and elevated premiums may be justified.
