Biggest stock gainers this upcoming week

For stocks that will be the “biggest gainers” next week, it’s impossible to know with certainty in advance. What we can do is narrow the universe to U.S. stocks that models suggest have a relatively high probability of rising and meaningful expected upside over the coming week, while staying in liquid, investable names. The filters your colleague used are designed exactly for that.

Screening Filters

1. market_cap ≥ 1,000,000,000 (≥ $1B)

   • Purpose: Focus on mid/large-cap companies and avoid very small, speculative microcaps.
   • Rationale:
     • The “biggest gainers” in percentage terms are often tiny microcaps, but they are also extremely risky, illiquid, and prone to manipulation.
     • A $1B+ market cap floor keeps the list in a more institutionally investable universe, where price moves are more likely driven by fundamentals or broad sentiment rather than pure speculation.
     • This fits a reasonable balance: still plenty of volatility potential, but in companies with real businesses and better disclosure.

2. monthly_average_dollar_volume ≥ 500,000

   • Purpose: Ensure stocks have sufficient trading liquidity.
   • Rationale:
     • “Biggest gainer” ideas are only useful if you can enter and exit without huge slippage.
     • A minimum of $500K traded per day on average filters out illiquid tickers where a few trades can distort prices and where you might move the market trying to trade.
     • This makes the results more actionable for most investors.

3. moving_average_relationship: PriceAboveMA20

   • Purpose: Select stocks already in a short-term uptrend.
   • Rationale:
     • Price above the 20-day moving average means the recent price is higher than the roughly one-month average, a classic sign of near-term strength.
     • For “upcoming week” gainers, you generally want momentum on your side rather than picking names already in clear downtrends.
     • This filter biases the list toward stocks where buyers are in control recently, increasing the odds of continued strength into next week.

4. region: United States

   • Purpose: Limit results to U.S.-domiciled companies.
   • Rationale:
     • The user explicitly asked for the “US market.”
     • This excludes foreign listings and ADRs from other regions, aligning the universe exactly with U.S. companies.

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

   • Purpose: Restrict results to major U.S. exchanges.
   • Rationale:
     • The “US market” typically means primary U.S. exchanges (NYSE, NASDAQ, AMEX), not OTC or pink-sheet names.
     • Major exchanges impose listing standards (financial reporting, governance, minimum price/size), which helps avoid very low-quality or easily manipulated stocks.
     • This keeps the candidate list to widely followed, more transparent companies where price signals and forecasts are more reliable.

6. one_week_rise_prob ≥ 60

   • Purpose: Select stocks with a relatively high model-estimated probability of rising over the next week.
   • Rationale:
     • Since you’re asking for “biggest gainers this upcoming week,” this filter uses a quantitative model’s estimate of the chance the stock’s price will be higher a week from now.
     • A 60%+ threshold effectively says: only show names where the odds of a positive week are meaningfully better than a coin flip.
     • This directly targets the probability of gains in the specific time horizon you care about.

7. one_week_predict_return ≥ 5 (%)

   • Purpose: Focus on stocks with meaningful expected upside in the next week, not just a slight move.
   • Rationale:
     • “Biggest gainers” implies substantial percentage moves, not 1–2% changes.
     • Requiring an expected 1-week return of at least +5% ensures the model anticipates a significant short-term move, not just modest drift.
     • Combining this with the rise probability filter targets stocks that are both likely to rise and meaningfully so.

Why Results Match Your Intent

• You’re asking for short-term, high-upside opportunities in the U.S. market.
  • The region and exchange filters keep the universe strictly to mainstream U.S. stocks.
• You want big gainers, not just any positive return.
  • The one_week_predict_return ≥ 5% filter ensures we only look at names where models expect sizable near-term moves.
• You want those gains next week, not just “sometime.”
  • The one_week_rise_prob and 1-week predicted return filters both explicitly use the 1-week horizon.
• You likely want tradable, non-microcap names.
  • The market cap and dollar volume filters avoid illiquid penny-type names and focus on stocks where you can realistically trade.
• You want stocks that have a decent chance of continuing to move up, not catching falling knives.
  • The PriceAboveMA20 filter aligns with short-term positive momentum, which historically increases the odds of further gains over the next few days.

Together, these filters don’t guarantee we’ll identify the absolute top gainer of the week (no screen can), but they systematically tilt the results toward liquid U.S. stocks with solid recent momentum and a relatively high model-estimated probability of strong gains over the coming week.
