Chinese Equity Screening with Turnover, Recent Limit-Ups, and Order Flow

Summary

The document describes a Chinese stock screen combining moderate turnover, at least one limit-up event in a recent lookback window, and a ranking based on net large-order flow. The stated rationale is that turnover approximates trading activity, a recent limit-up signals market attention, and net buying by large orders may indicate participation by substantial investors. It also gives example screening conditions and a Python-oriented data workflow, though the examples rely on particular data fields and provider interfaces.

The author cautions that the screen leans heavily on sentiment and flow measures, omits fundamentals, and may use unreliable large-order data vulnerable to speculative behavior. Suggested extensions include valuation, earnings, industry context, and technical indicators. The text does not provide a performance study, define a robust portfolio construction or exit method, or establish that order-flow signals predict returns. The proposed additions are suggestions rather than tested improvements, so the screen should be treated as a hypothesis requiring careful historical and live validation.

Key ideas

• The screen combines turnover in a stated range with a recent limit-up event and large-order net-flow ranking.
• Its rationale uses turnover as an activity measure and limit-ups as signs of attention and buying interest.
• The example workflow applies the conditions to Chinese equities using market data fields and provider calls.
• The document warns that order-flow data may be unreliable and that the approach omits fundamental factors.
• It reports no performance evidence or tested proof that the suggested additions improve selection.
