Which stock you will pick for today to buy?

Screening Filters

1. moving_average_relationship: PriceAboveMA20

   • Purpose: Select stocks whose current price is above their 20-day moving average.
   • Rationale:
     • You’re asking which stock to buy today for an upward move. That’s a short-term decision.
     • The 20-day moving average is a common short‑term trend indicator.
     • When price is above the 20‑day MA, it typically signals that recent momentum is bullish rather than bearish or sideways.
     • Applying this filter biases the choice toward stocks already in a short‑term uptrend, instead of trying to “catch a falling knife.”

2. one_day_rise_prob: min 55

   • Purpose: Require that the model-implied probability of the stock rising tomorrow (or next trading day) is at least 55%.
   • Rationale:
     • Your question is explicitly about which stock has the better chance to go up today/near term.
     • This filter translates that into a quantitative condition: only consider stocks where the next‑day up-move probability is meaningfully above a coin flip (50%).
     • Setting the bar at 55% doesn’t guarantee gains, but it improves odds versus random choice and aligns directly with your “chance to upward” focus.

3. one_day_predict_return: min 0.0001

   • Purpose: Ensure the model’s expected 1‑day return is positive.
   • Rationale:
     • A stock might have a high probability of a tiny gain or a low probability of a larger gain. This filter ensures the average expected outcome is still positive.
     • Even though 0.0001 is small (~0.01%), it explicitly excludes names where the model expects a negative or flat day.
     • Combined with the probability filter, this focuses on stocks that not only are more likely to go up, but also have a non‑negative expected magnitude of that move.

Why Results Match Your Question

• You asked which stock to pick today with a better chance of going up.
• The PriceAboveMA20 filter ensures we’re looking at stocks already in a short-term uptrend, fitting a “buy strength, not weakness” approach.
• The one_day_rise_prob ≥ 55 filter directly targets names with higher modeled odds of rising in the next session, aligning with your “chance to upward” wording.
• The one_day_predict_return > 0 filter reinforces that we’re not just picking “likely but tiny” moves; we’re requiring a positive expected short-term return.

Together, these filters translate your qualitative request—“which should I buy today for upside?”—into a systematic, probability- and trend-based stock selection approach.
