A Chinese Stock Screen Using Turnover, Recent Limit-Ups, and Fund Flows

Summary

This Chinese equities screening idea selects stocks with turnover between 3% and 12%, at least one limit-up event within the prior 25 days, and a nonnegative reading for the previous day’s main-fund control or flow measure. The post frames these conditions as a combination of liquidity, recent price strength, market sentiment, and large-player activity. It includes sample indicator logic and Python-oriented screening code, although the code’s data handling and implementation details do not fully establish that each condition is measured consistently.

The author cautions that relying too heavily on fund-flow signals can neglect company fundamentals, profitability, business quality, and financial condition, making results unstable. Suggested improvements include adding fundamental, industry, and financial variables, confirming fund-flow readings with other indicators, and adjusting the screen over time. No backtest results or evidence of predictive performance are supplied, so the criteria should be treated as a proposed screening recipe rather than a demonstrated strategy.

Key ideas

• The screen combines a specified turnover range with a recent limit-up event and a nonnegative prior-day fund-flow reading.
• The post presents liquidity, price action, sentiment, and large-player activity as the rationale for the filters.
• It recommends combining the signals with company fundamentals, industry context, and financial measures.
• The author warns that fund-flow dependence and changing market conditions can weaken the screen.
• No backtest evidence or demonstrated performance is provided.
