Chinese Stock Screen Using Price, Range, Turnover, and Auction Volume

Summary

The document proposes a Chinese equity screen based on a daily price range above a stated threshold, a product combining the prior day's turnover rate with the ratio of current auction volume to prior volume, and a closing price below 12. It frames these filters as a way to find lower-priced, active stocks while considering trading activity and market interest. The accompanying discussion warns that a low share price does not establish sound fundamentals and that timing and broader market conditions can affect outcomes. It suggests adding industry, business-growth, technical, and sentiment information.

The note supplies a Python example, but its implementation does not cleanly match the stated selection rule: it calculates range relative to closing price, derives turnover from volume and shares outstanding, and uses the latest daily volume ratio rather than explicitly measuring auction volume. It also provides no performance results, rebalance rules, or cost assumptions. The screen is therefore best treated as a rough candidate-generation idea, not evidence that the selected stocks are undervalued or likely to outperform.

Key ideas

• The proposed screen combines a price-range threshold, a turnover and auction-volume measure, and a low closing-price filter.
• The author identifies fundamental quality, timing, and market conditions as important risks.
• Suggested extensions include industry context, business growth, technical indicators, and sentiment.
• The sample implementation uses proxies that do not fully match the described auction-volume rule.
• No backtest evidence or trading and portfolio rules are provided.
