Combining Limit-Up Activity, Fund Flows, and Valuation in a Stock Screen

Summary

The document describes a Chinese stock screen that combines a daily increase in position share above 5%, Shenzhen main-board valuation limits, and more than two limit-up sessions within ten days. Its rationale treats the position-share measure as a possible sign of capital inflow, moderate price-to-earnings and price-to-book ratios as valuation filters, and repeated limit-ups as evidence of recent activity. The article later adds blue-chip industry classification and market capitalization above 5 billion yuan to its final criteria. It provides no backtest or outcome evidence.

The text warns that inflows do not guarantee gains, low valuation does not prove investment value, and recent limit-ups do not ensure continued investor attention. It suggests adding industry, size, and other technical indicators, but does not give a complete, validated implementation. The included code excerpt is truncated, and the screen lacks details on entry and exit rules, position sizing, and risk controls.

Key ideas

• The screen combines a position-share increase above 5% with valuation filters and recent limit-up activity.
• It requires more than two limit-up sessions within ten days.
• The final criteria also mention blue-chip classification and market capitalization above 5 billion yuan.
• The article gives a rationale for the filters but no performance evidence.
• The sample code is incomplete, and the strategy omits trade management and position sizing.
