High volume today

Screening Filters

1. Market Cap ≥ $1,000,000,000 (≥ $1B)

   • Purpose: Focus on larger, more established companies.
   • Rationale:
     • High trading volume in micro- or nano-cap names can be very erratic, news-driven, or even manipulation-prone.
     • By requiring at least $1B market cap, the screener emphasizes liquid, institutionally followed names where “high volume” is more meaningful and less likely to be a one-off anomaly.

2. Price ≥ $5

   • Purpose: Exclude penny stocks and very low-priced shares.
   • Rationale:
     • Low-priced stocks can show big volume spikes on small dollar flows, which can be misleading.
     • A minimum price threshold helps ensure that high volume reflects genuine investor interest rather than speculative or promotional trading in penny stocks.

3. Today’s Volume ≥ 20,000,000 shares

   • Purpose: Directly capture stocks with very high absolute trading volume today.
   • Rationale:
     • Your question is about “high trading volume today.” This filter explicitly sets a high bar for shares traded, so only heavily traded names appear.
     • 20M shares is a strong absolute volume figure for most stocks, indicating significant liquidity and activity.

4. Relative Volume (Rel Vol) ≥ 3

   • Purpose: Capture stocks trading at least 3× their normal volume.
   • Rationale:
     • Absolute volume alone can miss interesting names: a mega-cap might always trade 20M+ shares without anything unusual happening.
     • Relative volume compares today’s volume to the stock’s recent average (e.g., 10/30-day average). A value ≥ 3 means today’s activity is unusually high for that specific stock, flagging genuine volume surges.

Why Results Match Your Question

• The volume ≥ 20M filter directly targets stocks with high raw trading activity today.
• The relative volume ≥ 3 filter ensures those names are not just normally active, but experiencing an unusually high spike in volume today compared with their typical behavior.
• The market cap ≥ $1B and price ≥ $5 filters refine the list to more liquid, higher-quality names where high volume is more likely tied to meaningful catalysts (earnings, news, sector moves) rather than noise.
