Chinese Stock Screening with Price Range, Auction Volume, Turnover, and Positive Earnings

Summary

This Chinese equity screening proposal combines a daily price range above 1%, a ratio formed from the previous day’s turnover rate and the current auction volume relative to the previous day’s volume between 0.5 and 2, and a positive price-to-earnings ratio. The article presents the range as a measure of price movement, the volume and turnover terms as liquidity or market-interest filters, and positive earnings as a basic profitability screen. It also suggests considering industry, growth, technical indicators, market sentiment, and broader market conditions.

The rationale is qualitative; no backtest, performance results, or evidence of improved selection quality is supplied. The author cautions that the few criteria may overlook market trends, industry effects, and growth companies with non-positive earnings, and that results can depend on when the screen is run. The sample implementation does not cleanly match the described method: it uses daily volume data in the ratio and has inconsistencies in the fields it requests. Treat it as an illustrative proposal rather than a validated trading rule.

Key ideas

• The proposed screen combines a price range above 1%, a turnover and auction-volume ratio between 0.5 and 2, and positive earnings by the P/E filter.
• The article treats turnover and auction volume as liquidity or market-interest signals, alongside price movement and valuation.
• The sample code uses daily volume in the ratio, so it does not clearly implement the stated auction-volume condition.
• The author notes that industry, growth, market trends, and screening timing may affect candidate selection.
• No backtest or performance evidence is presented.
