Chinese Stock Screening with Turnover and Large-Order Flow

Summary

This Chinese stock selection post proposes screening for shares with daily turnover between 3% and 12%, a positive product of the day’s price change and net flow attributed to very large orders, and a listing age exceeding a stated threshold. Its explanation treats turnover as a measure of trading activity and combines price direction with large-order flow as a rough signal of market participation. The example implementation also refers to a minimum listing age of 1,800 days.

The post discusses risks and limitations rather than reporting a tested strategy. It warns that technical and flow conditions can select companies with weak fundamentals and may behave poorly during unusual market moves. It suggests adding valuation measures and studying trading volume and investor behavior. No backtest, benchmark, transaction-cost estimate, or performance evidence is supplied, and the code examples may not implement every stated condition consistently. The screen should therefore be understood as a hypothesis for further testing, not as evidence of an exploitable return.

Key ideas

• The proposed screen restricts daily turnover to a 3%–12% band.
• It uses the sign of the product of daily price change and large-order net flow as a directional filter.
• The example includes a listing-age requirement, with 1,800 days specified in its formula.
• The post notes that technical and order-flow filters can admit fundamentally weak companies.
• It provides no backtest or evidence of profitability, and its examples should be checked for consistency.
