Why Screening for IV Matters

Premium selling works best when implied volatility is elevated. But with thousands of optionable stocks, manually checking IV on each one is impractical. You need a systematic screening process to surface the best candidates daily.

The goal is simple: find liquid stocks where options are priced above their historical norms, then evaluate whether selling premium makes sense.

What to Screen For

Primary filter — IV Percentile above 50%: This is your starting point. Stocks with IV Percentile above 50% have options that are more expensive than usual. Above 65% is even better for premium sellers.

Secondary filters:

  • Average daily volume above 500K shares — ensures liquid options with tight bid-ask spreads
  • Option open interest above 5,000 — confirms active options trading
  • Stock price above $20 — avoids penny stocks with unreliable IV data
  • No earnings within 7 days — unless you're specifically trading earnings
  • Market cap above $2 billion — institutional-quality stocks with reliable pricing

    • Building Your Screening Workflow

    Step 1: Run the IV Percentile scan. Filter for stocks with IV Percentile above 50%. On a typical day, this produces 200-400 candidates from the broader universe of ~4,000 optionable stocks.

    Step 2: Apply liquidity filters. Narrow to stocks with average volume above 500K and option open interest above 5,000. This cuts the list to 80-150 stocks.

    Step 3: Remove upcoming earnings. Exclude stocks reporting within 7 days unless earnings trading is your goal. This reduces the list to 50-100 stocks.

    Step 4: Sort by IV Percentile. The highest IV Percentile stocks appear at the top. These have the most inflated premiums relative to their own history.

    Step 5: Evaluate the top 10-15 candidates. Check each for:

  • Why IV is elevated (news, sector movement, or general market fear)
  • Whether the premium justifies the risk
  • Technical support/resistance levels for strike selection
  • Fundamental quality (would you own this stock if assigned?)

    • Interpreting Screening Results

    Not every high-IV stock is a good trade. Context matters:

    Good high-IV trades:

  • IV elevated due to general market uncertainty (broad sector move)
  • Stock is near technical support (puts) or resistance (calls)
  • No imminent binary events
  • Strong fundamentals — you'd be comfortable owning the stock

    • Questionable high-IV trades:

  • IV elevated due to pending FDA decision or legal ruling (truly binary)
  • Stock has a history of gap moves that exceed the expected range
  • Low liquidity despite meeting minimum thresholds
  • Stock is in a clear downtrend (selling puts on a falling knife)

    • Sample Screening Results

    Here's what a typical scan might produce on a given day:

    | Stock | IV Percentile | Current IV | 52-Wk Avg IV | Reason | XOM78%32%24%Oil price volatility DIS72%38%28%Subscriber growth concerns BA85%45%32%Production issues in news JPM65%28%22%Banking sector uncertainty | PYPL | 71% | 42% | 31% | Competitive pressure |

    From this list, JPM and XOM might be the best candidates — well-known companies with manageable risk and IV elevated for sector-wide (not company-specific) reasons.

    From Screener to Trade

    Once you identify a candidate, OptionsPilot's strike finder takes the analysis further — showing you which specific strikes offer the best premium relative to their probability of profit. This bridges the gap between "this stock has high IV" and "here's the exact trade to place."

    Building the Habit

    Run your IV scan at the same time daily — ideally 30 minutes after the market open when IV levels stabilize. Keep a spreadsheet of stocks that appeared on your scan with high IV. Over time, you'll notice patterns: certain stocks cycle between low and high IV regularly, creating repeatable trading opportunities.
