Screening Small-Cap Stocks by Turnover, Profitability, and Opening Gaps
Summary
This A-share stock screen combines liquidity, company, and short-term price conditions. It selects stocks with turnover between 3% and 12%, market capitalization below 10 billion yuan, and no reported loss, then requires current trading volume above 10,000 lots and an opening price above the previous close. The article frames the filters as a way to find relatively liquid, financially non-loss-making stocks showing positive price action at the open. It includes example formula and Python implementations.
No backtest, return series, or measured risk statistics are supplied, so the screen’s effectiveness is not established. The article warns that targeting volatile stocks can carry substantial risk and that fixed filters may respond poorly to changing market conditions or exclude attractive companies. There are also implementation details to check: the prose refers to current volume and the prior close, while the sample code’s data handling may not reliably calculate that comparison; its market-cap and turnover checks also warrant verification before use. The strategy is best understood as a screening recipe rather than evidence of a profitable trading system.
