Chinese Stock Screen Combining Fund Flows and a Rising 30-Day Average

Summary

The proposed screen selects stocks with a rising 30-day moving average, positive net buying by large traders during the auction, and a daily position increase ratio above a stated threshold. The accompanying explanation interprets the flow measures as signs of buying interest and the moving average as an upward longer-term trend. It also outlines risks: apparent accumulation could precede distribution, and stocks with an already extended rise may be vulnerable to pullbacks.

The post recommends combining technical and fundamental measures, naming MACD, RSI, valuation ratios, and related inputs. It includes a Python example that attempts to prepare the filters, but the snippet is incomplete and its transformations and rolling calculations do not clearly match the described conditions. There is no backtest or evidence of predictive performance, and the meanings and data construction of the flow fields are not independently established. Treat the rules as a screening concept requiring validation rather than a tested strategy.

Key ideas

• The screen combines a rising 30-day average with positive auction net buying and a high position increase ratio.
• The author interprets the two flow measures as evidence of buying interest.
• The document warns that buying signals may precede distribution and an upward trend may be mature.
• It proposes adding technical and fundamental measures for broader assessment.
• The supplied Python example is incomplete and does not establish that the screen works as intended.
