Daily momentum stocks

Screening Filters

1. relative_vol ≥ 1.5

   • Purpose: Capture stocks trading with unusually high volume compared to their normal activity.
   • Rationale: Daily momentum moves are typically accompanied by a volume surge, showing strong participation and conviction. A relative volume of 1.5+ means the current day’s volume is at least 50% higher than average, which is a classic sign of active momentum.

2. moving_average_relationship: PriceAboveMA20

   • Purpose: Ensure the stock’s price is in a short-term uptrend.
   • Rationale: For “momentum” you generally want stocks trading above a key short-term moving average. Being above the 20‑day moving average means price is trending higher in the recent month, aligning with bullish momentum rather than a random spike in a downtrend.

3. price_change_pct ≥ 3% (for the day)

   • Purpose: Focus on stocks with a meaningful single-day price move.
   • Rationale: Daily momentum stocks typically have strong intraday or one-day price acceleration. A move of at least +3% filters out minor fluctuations and highlights names showing significant positive momentum on that day.

4. list_exchange: XNYS, XNAS, XASE (NYSE, NASDAQ, AMEX)

   • Purpose: Restrict results to major U.S. stock exchanges.
   • Rationale: The user asked for the “US stock market.” These three exchanges contain the bulk of U.S.-listed, actively traded stocks. Limiting to them avoids OTC/pink-sheet names that may be illiquid or highly speculative.

Why Results Match the User’s Request

• “Daily momentum” implies strong price movement today → captured by the ≥ 3% daily price change filter.
• Momentum should be supported by strong trading activity → ensured by relative volume ≥ 1.5.
• Momentum is more meaningful if it fits into an ongoing short-term uptrend → enforced by price above the 20‑day moving average.
• The focus is the U.S. stock market → ensured by restricting to NYSE, NASDAQ, and AMEX listings.

Together, these filters find U.S. stocks that are not only moving sharply today, but are doing so with high volume and within a short-term bullish trend—exactly the type of profile typically described as “daily momentum stocks.”
