Chinese Stock Screening with Fund Growth, Buying Flows, and Trend

Summary

This note proposes a Chinese equity screen combining a reported increase in buying activity, year-over-year parent-company net profit growth between 20% and 100%, and a 20-day moving average above the 120-day average. The buying-flow condition is presented as a sign of market interest, while the profit-growth band seeks companies with improving earnings and the moving-average relationship seeks a positive trend. In its suggested refined version, the document adds price-to-earnings below 20 and price-to-book below 2 as valuation filters.

The article explains possible drawbacks: unusually strong buying or earnings growth can coincide with overvaluation, and a strong short-term trend can reverse. It suggests adding valuation and technical measures, but it supplies no backtest, benchmark, or measured return evidence. Its sample code is illustrative and appears inconsistent with the prose: the earnings-growth calculation does not clearly calculate a year-over-year percentage, and the moving-average filter references a 120-day average without showing its calculation. The screen therefore needs careful data and implementation checks before its behavior can be assessed.

Key ideas

• The proposed screen combines a buying-flow measure above 5%, bounded year-over-year profit growth, and a bullish moving-average relationship.
• The refined version adds price-to-earnings and price-to-book limits.
• The document warns that heavy inflows and fast earnings growth can coincide with overvaluation.
• No backtest or measured performance evidence is provided.
• The sample code has implementation inconsistencies that could change the screen’s results.
