Screening Small Profitable Stocks with Auction Activity and Large Orders

Summary

This article describes a Chinese stock screen combining daily amplitude, a pre-open auction price-move condition, large-order buying, a market capitalization ceiling of 10 billion yuan, and positive company profit. Its stated aim is to blend price movement and trading activity with company size and profitability. The document supplies a platform formula and sample Python-style filtering logic, including an order-flow threshold and a market-cap threshold. The conditions are presented as a selection recipe, not as a tested trading system.

The article identifies several limitations: it does not account for future business prospects, macroeconomic or policy changes, and may produce few selections in concentrated sectors. It suggests loosening filters to increase the number and diversity of candidates, and incorporating market and economic context. The examples contain differing expressions of some thresholds and auction variables, so the implementation details may not map cleanly across platforms or data fields. No performance results, benchmark comparison, or evidence that these signals forecast returns is included.

Key ideas

• The screen combines price amplitude, auction activity, large-order buying, a market-cap ceiling, and positive profit.
• The article provides example platform and Python-style implementations, but they are not shown to have been tested.
• The author notes that macroeconomic conditions and company prospects are omitted and the screen may yield few stocks.
• Some threshold and variable expressions differ between examples, so implementation requires checking the data definitions.
