A Stock Screen Using Turnover, Prior-Day Leaderboard Activity, and the 10-Day Average

Summary

The article describes a stock selection rule requiring turnover between 3% and 12%, appearance on the previous day’s trading leaderboard, and an opening price near the 10-day moving average. Its formula example defines “near” as within 2% of that average. The author presents moderate turnover and recent leaderboard activity as signals of market attention, with the moving average providing a simple technical reference. A Python example applies these filters to a stock data table.

The document warns that the rule uses a small set of technical conditions and omits broader market and company fundamentals, which may reduce its reliability and cause many traders to select the same names. It suggests supplementing the screen with other technical indicators, financial information, company results, and industry trends. No backtest, return data, or evidence of predictive accuracy is supplied, so the screen is a hypothesis for further evaluation rather than a demonstrated strategy.

Key ideas

• The screen combines a turnover range, previous-day leaderboard activity, and an opening price close to the 10-day moving average.
• The example defines proximity to the moving average as a difference below 2%.
• The author notes that a small set of technical filters omits important market and company information.
• Shared use of simple conditions may cause traders to select overlapping stocks.
• The document offers no backtest evidence and recommends further analysis with additional indicators and fundamental data.
