A Simple Chinese Stock Screen Using Price and Daily Range

Summary

The post describes a basic screen for mainland Chinese shares whose codes begin with a specified Shanghai prefix, whose closing price is 18.5 yuan, and whose intraday range exceeds one percent under the formula shown. It suggests sorting candidates by trading value and presents example implementations for a screening platform and a data library. The author frames the criteria as a way to find relatively volatile stocks at a chosen price level.

The post acknowledges that this narrow filter ignores company performance, growth prospects, industry conditions, and broader market trends. It recommends adding fundamental and industry analysis, a liquidity screen based on tradable market value, and profit-taking and loss controls. No backtest, performance statistics, or evidence that the screen predicts returns is supplied. The examples are implementation sketches, so users would need to verify field availability and logic before relying on them.

Key ideas

• The screen combines a one percent intraday range threshold, a closing price of 18.5 yuan, and a Shanghai stock code prefix.
• The post proposes sorting qualifying stocks by trading value.
• The author identifies limited fundamental and market context as key weaknesses.
• Suggested refinements include liquidity filters, industry analysis, market trends, and exit controls.
• The document provides no backtest or evidence of predictive performance.
