Chinese Stock Screen Using Turnover, Recent Limit-Ups, and Position Growth

Summary

This Chinese A-share screening idea combines a daily turnover range of 3% to 12%, at least one limit-up event in the prior 25 days, and a current position-growth ratio above 5%. The article interprets turnover as a measure of trading activity, recent limit-up activity as a sign of market attention, and position growth as evidence of buying interest. It suggests adding financial measures such as profit, net assets, and valuation ratios to assess the businesses behind the price signals.

The document provides indicator-formula and Python examples, but the implementations do not consistently match the stated rule: the Python excerpt uses a return threshold in place of the position-growth measure and applies a historical turnover quantile. The article reports no backtest or performance evidence. Its main caveat is that activity and flow signals alone can overlook weak fundamentals, and additional filters would still require testing before the screen could support an investment decision.

Key ideas

• The screen combines 3% to 12% turnover with a limit-up event during the preceding 25 days.
• It requires current position growth above 5% as a buying-interest signal.
• The article recommends adding financial measures such as profits, net assets, and valuation ratios.
• The examples do not fully implement the stated criteria consistently, and no performance evidence is provided.
