How to Use Implied Volatility Screeners Effectively

Understanding IV Basics

Implied volatility measures what the market expects for future price changes.

High IV means bigger expected moves, while low IV points to smaller ones.

Options with high IV cost more than those with low IV.

This difference helps traders spot options that might be overpriced or underpriced.

Practical Screening Steps

1. Compare Current IV to Historical Levels

Look for stocks with IV readings at extreme ends:

  • High IV percentile (80%+): Options could be overpriced
  • Low IV percentile (20% or lower): Options might be underpriced

2. Check IV Term Structure

See how volatility shifts across different expiration dates:

  • Higher short-term IV than long-term: Market expects immediate news
  • Lower short-term IV than long-term: Suggests normal conditions

3. Identify IV Skew Patterns

Check how volatility varies across strike prices:

  • Higher IV for downside strikes: Market fears drops
  • Higher IV for upside strikes: Market expects rallies

4. Match Strategies to IV Conditions

Choose strategies based on IV readings:

  • High IV: Maybe sell options (credit spreads, iron condors)
  • Low IV: Maybe buy options (debit spreads, long calls/puts)
  • IV crush coming? Use strategies that benefit from volatility dropping

5. Monitor IV Changes

Track how volatility moves over time:

  • Rising IV: Could signal upcoming market events
  • Falling IV: Often follows news releases
  • Sudden IV spikes: Might mean breaking news

Trading Applications

For Earnings Plays:

  1. Find stocks with earnings reports coming up
  2. Check if current IV is higher than previous earnings periods
  3. Consider strategies that profit if IV drops after earnings

For Range-Bound Markets:

  1. Screen for stocks with high IV and strong technical support or resistance
  2. Look for IV percentiles above 75%
  3. Consider iron condor or short strangle strategies

For Directional Trades:

  1. Find stocks with low IV but strong directional signals
  2. Confirm IV percentile is below 30%
  3. Consider long calls/puts or debit spreads

Conclusion

Implied volatility screeners can really help traders spot interesting options opportunities.

Every platform brings its own quirks and strengths, which means there’s something out there for every trading style.

If you’re just starting out, stick with basic IV comparisons. As you get the hang of things, try diving into more advanced volatility analysis.

Keep in mind, IV just shows what the market expects, it’s not a crystal ball for future prices.
