Today exploding stocks

Screening Filters

1. Market Cap ≥ $500,000,000

   • Purpose: Focus on established, reasonably sized companies.
   • Rationale:
     • The user is asking about “which stocks” are up significantly today, not micro‑caps or ultra‑speculative names.
     • A minimum market cap of $500M filters out many tiny, illiquid companies whose prices can move wildly on very little news or trading.
     • This makes the list more relevant and investable for most users, and reduces the chance that big percentage moves are just random noise.

2. Price ≥ $5

   • Purpose: Exclude penny stocks and very low‑priced shares.
   • Rationale:
     • Penny stocks can show huge percentage increases (e.g., +50%) on just a few cents of movement, which often doesn’t represent “significant” moves in a meaningful, tradable sense.
     • By requiring a price of at least $5, the screener targets stocks where a 5–10% move reflects more substantial changes in demand, news, or fundamentals, aligning better with the idea of “significant price increases” in normal investing contexts.

3. Volume ≥ 1,000,000 shares (today)

   • Purpose: Ensure the stocks are actively traded and the price move is backed by real liquidity.
   • Rationale:
     • A stock that jumps on a few thousand shares traded might not be reliable or easy to trade without large spreads and slippage.
     • A minimum of 1M shares traded today indicates broad market participation in the move, which supports the idea that the price increase is meaningful and not just a thin, easily reversed spike.
     • This helps users see stocks where “significant price increases” are visible to and tradable by the broader market.

4. Today’s Price Change % ≥ 5%

   • Purpose: Directly capture “significant price increases” on the current day.
   • Rationale:
     • This is the core filter responding to “Today, which stocks are experiencing significant price increases?”
     • A threshold of +5% is a common benchmark in markets to define a notable daily move, especially for mid‑cap and large‑cap stocks.
     • It ensures that only stocks with a clearly above‑average positive return for the day are included, precisely matching the user’s focus on big movers today.

5. 1‑Week Price Change % ≥ 0%

   • Purpose: Avoid stocks that are sharply up today but still in a short‑term downtrend.
   • Rationale:
     • Some stocks can bounce sharply (e.g., +8% today) after falling heavily earlier in the week, yet still be down over the last 7 days.
     • Requiring the 1‑week performance to be at least flat (≥ 0%) filters out many “dead‑cat bounces” and focuses on names where today’s strong move is part of a flat or improving short‑term trend.
     • This aligns with a practical interpretation of “significant price increases” as part of a constructive move rather than a brief spike in a still‑weak stock.

Why Results Match the Question

• The today’s price change filter (≥ 5%) directly targets stocks with large positive moves today, which is exactly what the user asked for.
• Market cap, price, and volume filters ensure these gains are in reasonably established, liquid, and tradable stocks, not obscure penny or micro‑cap names whose moves are often noise.
• The 1‑week performance filter helps highlight stocks where today’s big move isn’t just a one‑day blip against a sharply negative recent trend, making the list more meaningful for identifying true “strong gainers” rather than random volatility.
