Chinese Stock Screening with Buying Activity, Golden Crosses, and Market-Cap Limits

Summary

This Chinese stock-screening note combines three conditions: buying volume above 5% of total trading volume, simultaneous golden-cross signals from technical indicators, and a market capitalization below 10 billion yuan. The article describes golden crosses as possible signs of an upward price trend and interprets elevated buying activity as potential inflow. It also mentions ranking qualifying stocks by return, though the ranking step is not fully explained.

The note cautions that market volatility and indicator errors can undermine the screen, and that relying on these conditions alone may create selection bias. It suggests broadening the technical and fundamental inputs, including company profitability and financial condition. The example code's market-cap threshold appears inconsistent with the stated limit, and its indicator logic does not clearly implement three separate golden crosses. No backtest results or evidence of performance are provided, so the screen should be treated as a rule proposal rather than a validated strategy.

Key ideas

• The proposed screen requires buying volume above 5% of total volume.
• It combines that flow condition with three simultaneous technical golden crosses.
• The stated market-cap ceiling is 10 billion yuan, although the example code uses a different threshold.
• The article identifies volatility, signal errors, and omitted factors as risks.
• It provides no performance test supporting the proposed rules.
