Chinese Small-Cap Screen Using Auction Activity and Positive Earnings

Summary

This note outlines a Chinese equity selection approach that first limits candidates to companies with market capitalization below 10 billion yuan and no losses, then ranks them by capital strength and selects the top five by the day’s auction amount. The stated rationale is that capital strength and auction activity may indicate investor attention, while profitability and a size ceiling define the company universe. It recommends adding valuation measures such as PE and PB and refreshing the filters as market conditions change.

The evidence is conceptual: the note explains the intended filters and mentions a rolling net money flow calculation in a partial code example. It supplies no backtest, return figures, or definition of the auction amount and capital-strength metrics sufficient to reproduce the ranking. The author also notes that flow and auction rankings can reflect short-term sentiment, overlook quieter candidates, and fail to account for changing industry or market conditions.

Key ideas

• The universe is restricted to profitable companies below the stated market-capitalization ceiling.
• Candidates are ordered by capital strength and ranked by auction amount, with the top five selected.
• The note proposes adding valuation measures and updating the screen over time.
• The partial code and missing metric definitions leave the ranking difficult to reproduce, and no performance results are given.
