A Chinese Stock Screen Combining Fund Flows, Recent Limit-Ups, and Small Market Caps

Summary

This Chinese-language post outlines a stock selection screen that ranks companies by a capital-strength measure, filters for a limit-up event within the prior 25 days, and restricts market capitalization to below 10 billion yuan. It interprets strong inflows and recent limit-ups as signs of investor attention and activity, while treating the size ceiling as a way to focus on smaller firms. The post offers a qualitative rationale for each filter rather than a defined calculation or reproducible strategy.

Its risk discussion notes that flow measures can reflect shifting market conditions and sentiment, a limit-up may follow excessive speculation, and smaller firms can face weaker liquidity or attention. It suggests adding other flow, market, and capitalization measures, but provides no evaluation, performance evidence, entry or exit rules, or portfolio controls. The included code fragment is incomplete and does not implement the screen, so the document is best read as a rough screening concept rather than a tested trading system.

Key ideas

• The screen ranks stocks by a capital-strength measure intended to identify larger inflows.
• It requires at least one limit-up event within the previous 25 days.
• It limits selection to companies with market capitalization below 10 billion yuan.
• The post warns that inflows, limit-ups, and small capitalization each carry interpretation or liquidity risks.
• It gives no backtest or complete implementation of the proposed screen.
