A-Share Small-Cap Screen Using Profitability and Institutional Flows

Summary

This document outlines a Chinese stock screen for companies valued below 10 billion yuan that have not reported losses, alongside positive institutional activity and a daily position-increase share above 5%. The rationale is that buying activity may signal investor attention, while the size and profitability filters target smaller firms with a record of avoiding losses. The described final rule further proposes price-to-earnings below 30, price-to-book below 2, and no losses over the past five years.

The post includes illustrative data-processing code, but no backtest or evidence that the signals predict returns. It warns that large inflows may precede excessive short-term rises and that smaller firms may have limited liquidity. The definitions and data sources for institutional flows and daily position increases are not clearly established, and the code example appears inconsistent with some stated conditions. Those details, along with reporting lags in financial data, would need clarification before evaluation.

Key ideas

• The screen combines a market-cap ceiling, a profitability history, and positive institutional activity.\nThe daily position-increase share must exceed 5%.\nThe refined criteria add price-to-earnings below 30 and price-to-book below 2.\nThe post warns of short-term overheating and limited liquidity among smaller companies.\nNo performance evidence is given, and the flow measures and example code need careful validation.
