Chinese Small-Cap Stock Screen Using Profitability and Institutional Buying

Summary

The post describes a China-focused stock screen combining reported institutional buying, a recent increase in buying activity above five percent, market capitalization below 10 billion yuan, and a history without losses. It then presents a more restrictive final selection logic that adds price-to-earnings below 20 and price-to-book below 2. The author frames the signals as ways to identify financially stable smaller companies attracting capital.

The article discusses possible drawbacks: concentrated inflows can precede a pullback, institutional decisions can be wrong, and past profitability does not guarantee future operating strength. It suggests adding valuation and technical filters, but offers no backtest, return data, or evidence that the screen predicts performance. The accompanying code reference is illustrative and its field definitions and filters do not clearly match every stated rule, so the screening logic would need validation against a reliable data source before use.

Key ideas

• The screen combines reported institutional buying with recent buying activity above five percent.
• It seeks companies valued below 10 billion yuan that have not reported losses.
• The final stated rules add price-to-earnings below 20 and price-to-book below 2.
• The post identifies reversal risk, incorrect institutional judgments, and deteriorating fundamentals as risks.
• No performance evidence is provided, and the code example does not clearly implement all stated criteria.
