Stock Screening with Turnover, Profit Growth, and Auction Volume

Summary

This Chinese-language post describes an equity screen combining turnover, year-over-year net profit growth attributable to parent-company shareholders, and a ratio involving prior turnover, current auction volume, and previous volume. It selects stocks with turnover from 3% to 12%, profit growth above 20% and up to 100%, and the specified volume ratio between 0.5 and 2; it then ranks candidates by market value and presents the top five. The post includes example formulas and a Python workflow using BaoStock data.

The author says the volume condition is intended to add a liquidity consideration while retaining a fundamental filter. The post cautions that volume does not fully measure liquidity, the selected financial data may not capture company conditions accurately, and market risk and volatility are not addressed. It suggests adding financial and industry variables, technical indicators, and other measures such as amplitude. No backtest results or evidence of profitability are provided, and the sample code’s data fields and timing would need validation before use.

Key ideas

• The screen combines a turnover range with a bounded year-over-year profit growth filter.
• A ratio using turnover and auction-to-prior volume is used as an additional selection condition.
• The example ranks qualifying stocks by market value and retains five candidates.
• The post warns that volume is an imperfect liquidity proxy and financial data can be incomplete.
• It offers no performance evidence and suggests adding industry, financial, and technical measures.
