Chinese Stock Screen for Small, Profitable Firms and Increased Holdings

Summary

This proposed Chinese stock screen combines three filters: market capitalization below 10 billion yuan, no reported losses, and a measure of today’s increased holdings above 5%, while excluding stocks that hit the daily limit yesterday. The accompanying explanation interprets increased holdings as a possible sign of capital inflow and the prior-day exclusion as a way to avoid buying immediately after a sharp rise. It also notes that small capitalization alone does not establish upside potential and that weak market conditions can undermine the selection.

The article recommends adding profitability and financial-health measures and using technical analysis as further checks. Its code is illustrative rather than operational: helper functions are undefined or self-referential, the filter checks after the first return are unreachable, and the asserted holdings-flow measure is not clearly defined. The document gives no backtest, sample, or performance data, so it does not establish that the filters predict returns. Its main value is as a rough screening hypothesis that would need precise data definitions and independent testing.

Key ideas

• The proposed screen combines a sub-10-billion-yuan market-cap ceiling, no losses, increased holdings above 5%, and no limit-up session the prior day.
• The article treats increased holdings as a possible indication of capital inflow, not proof of future gains.
• Small capitalization and recent flow measures do not guarantee a stock has upside potential.
• The sample code has undefined and self-referential functions and unreachable filter checks.
• No performance evidence is supplied, so the screen requires precise definitions and testing.
