A Stock Screen Using Turnover, Trading Pressure, and Control
Summary
The article proposes selecting stocks with turnover between 3% and 12%, an external-to-internal trading volume ratio above 1.3, and a daily control reading above 21%. The stated rationale is to find stocks with meaningful trading activity and buying pressure. It includes example formulas and a Python sketch intended to implement the screen, and suggests adding technical indicators or financial data as possible refinements.
The article provides no performance results, portfolio rules, or backtest evidence, and it acknowledges that the conditions omit other influences on price. The implementation examples also do not clearly match the stated criteria: the formula uses a close-to-previous-close ratio where the text specifies turnover, and the Python sketch checks a KDJ field rather than the stated control measure. The screen should therefore be treated as a rough proposal, with definitions and code reconciled before evaluation.
Key ideas
- The proposed screen combines a turnover range, a trading-volume pressure ratio, and a daily control threshold.
- The stated intent is to identify stocks with active trading and stronger buying pressure.
- The article offers formulas and a Python sketch but reports no measured strategy performance.
- The provided implementations appear inconsistent with some of the stated screening conditions.
- Additional market and company factors may affect results beyond these three filters.
