Screening Stocks with RSI, Earnings Growth, and Concentration Limits

Summary

This Chinese A-share screening proposal combines a technical condition with earnings growth and a concentration filter. It selects stocks with a 14-period RSI below 65, year-over-year net-profit growth above 20% and no more than 100%, and a stated concentration ratio below 70%. The accompanying SQL example also applies listing, trading-status, valuation-data, and minimum market-capitalization filters. The article frames the screen as a way to find growing companies while avoiding excessive concentration.

The post offers code references but no backtest results or evidence that the screen produces superior returns. Its explanation that a lower RSI may leave room for gains is an interpretation, not a demonstrated effect, and the concentration measure in the examples may not map cleanly to the prose description. The author notes that the filters can exclude strong companies and omit other useful fundamentals and technical signals. Sector-specific criteria and additional measures such as profitability or valuation are suggested as possible refinements.

Key ideas

• The screen combines RSI below 65 with bounded year-over-year net-profit growth and a concentration ceiling.
• The proposal mixes technical and fundamental criteria for selecting Chinese equities.
• The post provides sample SQL and Python references but reports no performance evaluation.
• The filters may exclude strong firms, and the concentration definition should be checked against the intended measure.
• Adding sector-aware criteria and other fundamental or technical variables is suggested as a refinement.
