A-Share Screen Using Turnover, RSI, and a Beijing Exclusion

Summary

This post presents a basic A-share stock screen that selects stocks with turnover between 3% and 12%, excludes Beijing-listed stocks, and requires a 14-period RSI below 65. It frames turnover as a liquidity filter and RSI as a way to identify stocks that may be recovering from relatively low levels. The post also gives example implementations for a screening formula and a Python workflow that retrieves stock and indicator data.

The selection rationale is asserted rather than supported with performance evidence: there are no backtest results, sample dates, benchmark comparisons, or transaction-cost estimates. The explanation also cautions that the RSI threshold can affect signal quality and that excluding a market segment reduces the candidate universe; it suggests validating indicators and adding risk controls. The code excerpt contains inconsistent market exclusions and turnover comparisons, so its implementation should be checked carefully before use. This is best treated as an initial screening idea, not a validated strategy.

Key ideas

• The proposed screen combines a turnover range, an exclusion of Beijing stocks, and a 14-period RSI threshold.
• The post describes turnover as a liquidity filter and RSI as a way to find potential rebounds.
• It recommends validating the signal with other technical or fundamental measures and adding risk controls.
• No backtest evidence is provided, and the sample code has inconsistencies that require review.
