Screening Main-Board Stocks by Turnover and Daily Gains

Summary

The document presents a stock screen for main-board listings that have risen during the day and fall within specified turnover-rate ranges. It describes one range of three to twelve percent and also includes a second range of two to nine percent; taken together, these conditions narrow eligible turnover to their overlap. The accompanying formulas and Python example add a daily gain filter, trading-volume condition, and main-board identifier check. The stated rationale is to focus on stocks with noticeable price movement and moderate trading activity.

The article acknowledges that the screen relies on technical conditions and omits company fundamentals and industry outlook. It suggests combining the rules with profitability, valuation, growth, and other technical measures. No historical test, risk-adjusted performance, or evidence of predictive value is reported. The source also contains inconsistent implementation details: the prose and code do not align perfectly on return thresholds and market identifiers, and the overlapping turnover filters are redundant unless their intersection is intended. Those details need resolution before the screen can be reproduced reliably.

Key ideas

• The proposed screen combines a daily gain threshold, main-board membership, and turnover-rate limits.
• The stated turnover ranges overlap, so applying both simultaneously restricts selection to their shared interval.
• The example also includes a minimum trading-volume condition.
• The article recommends adding fundamental and other technical measures but gives no tested optimized version.
• No backtest or performance evidence is provided, and some prose and code conditions differ.
