Ranking Profitable Small-Cap A-Shares by Auction Trading Activity

Summary

This A-share selection rule first screens for turnover between 3% and 12%, market capitalization below 10 billion yuan, and companies described as having no losses. It then ranks qualifying shares by the day’s auction amount and proposes investing in the top five. The post frames auction activity as a signal of trading interest and market sentiment, and includes example formula and Python approaches; it also notes that source-specific field names may differ.

The author cautions that activity-based ranking can overemphasize trading volume and sentiment while overlooking company finances, macroeconomic conditions, policy, and longer-term prospects. The suggested improvement is to combine the ranking with broader business and market analysis. The post supplies no historical test, return figures, precise definition of auction amount, or complete portfolio and risk rules. Its example implementation also needs careful validation against the intended data definitions before use.

Key ideas

• The proposed universe has turnover between 3% and 12%, market value below 10 billion yuan, and no reported losses.
• Qualifying shares are ranked by auction amount, with the top five selected.
• The post treats high auction activity as an indicator of trading interest but warns against relying on it alone.
• No backtest, performance results, or complete position and risk rules are supplied.
