A-Share Stock Screen Using Range, Turnover, and Daily Gains

Summary

This document presents a daily stock-selection screen for mainland Chinese main-board equities. It combines an intraday high-low range above 1%, turnover bounded between 2% and 9%, and a close more than 1% above the prior close. The article also supplies indicator formulas and a Python example, though some implementation details do not consistently match the prose: the example uses volume relative to total shares as turnover, and its range condition is expressed as a price difference rather than a percentage.

The rationale is to favor stocks showing activity, liquidity, and positive short-term movement. The article does not report a backtest or performance evidence, and it notes that policy, industry, macroeconomic, and news developments can affect outcomes. It recommends incorporating fundamental analysis and risk controls, but does not specify or evaluate them. The screen is therefore a set of candidate filters, not evidence of a validated or reliably profitable strategy.

Key ideas

• The screen selects main-board stocks with an intraday range above 1%, turnover between 2% and 9%, and a daily gain above 1%.
• Its stated rationale combines trading activity, liquidity, and short-term price direction.
• The sample implementations contain differences from the written criteria, especially in turnover and range calculations.
• The document gives no backtest results and identifies market and company-specific risks.
