Large cap gainers

Screening Filters

1. market_cap_category: large

   • Purpose: Limits the search to large-cap companies.
   • Rationale: The user asked for “large-cap gainers,” so this is the core size filter. Large-cap stocks generally represent established, higher-market-value companies and ensure the screen matches the requested universe.

2. relative_vol: min 1.5

   • Purpose: Finds stocks trading with above-normal volume.
   • Rationale: Gainers with elevated volume are often more meaningful because strong price moves backed by heavier trading can signal stronger investor interest and better momentum confirmation.

3. moving_average_relationship: PriceAboveMA20, PriceAboveMA200

   • Purpose: Selects stocks trading above both the 20-day and 200-day moving averages.
   • Rationale: This helps identify stocks with short-term strength and longer-term uptrends. For “gainers,” this filter favors stocks already in an upward trend rather than short-lived rebounds or weak names.

4. ema_20: min 0

   • Purpose: Ensures the stock’s price is not below the 20-day EMA.
   • Rationale: This supports the short-term momentum requirement by favoring stocks holding near or above near-term trend support.

5. ema_60: min 0

   • Purpose: Ensures the stock’s price is not below the 60-day EMA.
   • Rationale: This adds another layer of trend confirmation, helping screen for stocks with sustained intermediate-term strength, which is consistent with “gainers.”

6. week_price_change_pct: min 0

   • Purpose: Requires the stock to be up over the past week.
   • Rationale: This directly captures recent positive performance, aligning with the “gainers” part of the request.

7. month_price_change_pct: min 0

   • Purpose: Requires the stock to be up over the past month.
   • Rationale: This helps ensure the stock has positive momentum over a slightly longer recent period, reducing the chance of selecting only very short-term spikes.

Why Results Match:

• The screen focuses on large-cap stocks that are currently showing positive price momentum.
• By requiring the stock to be above key moving averages and up over both the week and month, it favors names that are not just temporarily bouncing, but are in a broader upward trend.
• The relative volume filter adds confirmation that the move is supported by trading activity, which often makes the gainers more notable and actionable.
