Screening Chinese Stocks by Buying Activity, Earnings Growth, and 10-Day Returns

Summary

This A-share screening idea combines three signals: a reported increase in buying activity above 5%, year-over-year parent-company net profit growth above 20% and no more than 100%, and a positive 10-day return below 35%. The article then proposes adding valuation limits of price-to-earnings at or below 20 and price-to-book at or below 2. It also offers a ranking example that adds buying activity, earnings growth, valuation ratios, and return into one score, then selects the top five stocks.

The rationale is that buying activity and recent gains may indicate market interest, while earnings growth and valuation filters add fundamental context. The article gives no backtest or performance evidence. It flags risks including possible price manipulation, unreliable financial reporting, and short-term price fluctuations. The sample scoring approach has methodological limitations: it sums quantities with different units and does not explain normalization, data timing, or how the stated thresholds relate to the ranking. Treat it as a rough screening proposal requiring careful implementation and validation.

Key ideas

• The screen combines buying activity, parent-company profit growth, and positive but capped 10-day returns.
• The proposed refinement adds price-to-earnings and price-to-book ceilings.
• The article suggests ranking candidates by a combined score and taking the top five.
• It warns that flows, reported earnings, and short-term returns can each give misleading signals.
• The example score combines differently scaled measures without describing normalization or validation.
