Screening Main-Board Stocks by Turnover, Daily Gain, and Recent Surge

Summary

This proposed equity screen looks for main-board stocks with turnover between 3% and 12%, a daily gain above 1%, and at least one day with a gain of 10% or more during the prior 25 trading days. The document frames a large recent daily move as a sign of possible price strength and combines it with current turnover and return conditions. It includes sample formula and Python logic, but reports no backtest, portfolio results, or other evidence that the screen has predictive value.

The author acknowledges that a short-term strength filter can neglect longer-term company performance and fundamentals, and that subjective thresholds may contribute to selection bias or excessive trading. Broader technical, fundamental, and industry measures, alongside money management, are suggested as possible additions. There are inconsistencies between the written screen and portions of the formula example, so the implementation details require verification before they can be relied on.

Key ideas

• The screen requires turnover between 3% and 12% and a daily gain above 1%.
• It also requires at least one daily gain of 10% or more in the prior 25 trading days.
• The stated universe is main-board stocks, with recent large gains treated as a possible strength signal.
• The document cautions that short-term price filters omit longer-term fundamentals and may encourage excess trading.
• No performance evidence is provided, and some sample formula details differ from the written criteria.
