Chinese Stock Screening with Fund Inflows and a Rising 30-Day Average

Summary

This post presents a Chinese equity screening rule that combines a recent increase in reported fund allocation with a bounded daily price change and a rising 30-day average. It interprets the fund measure as evidence of buying interest, the price-change band as avoiding especially large daily moves, and the rising average as a longer-term upward trend. The proposed final screen also adds market-capitalization and price-to-earnings constraints.

The post lists risks for each condition, including price inflation after heavy inflows, limited near-term gains from small moves, and losses if a longer-term uptrend reverses. It suggests adding valuation or size filters and shorter moving-average periods. A sample data workflow is included, but it has apparent inconsistencies between the stated screening logic and the fields and thresholds in the example. No backtest results or evidence of profitability are provided, so the rules should be treated as an illustrative screen rather than a validated strategy.

Key ideas

• The screen combines a fund-increase threshold, a limited daily return range, and an upward-sloping 30-day average.
• The proposed final version adds minimum market capitalization and a maximum price-to-earnings ratio.
• The post suggests shorter moving averages and additional fundamental filters as possible refinements.
• The example workflow does not fully match the described rules and provides no performance validation.
