Screening Chinese Stocks for Volatility, Recent Gains, and Auction Activity

Summary

The proposed stock screen looks for shares with a daily range above a threshold and at least one large one-day gain during the preceding 25 trading days. It then ranks candidates using opening auction amount, with the initial description selecting the five highest. The rationale is to combine volatility, recent price strength, and an indication of early-session trading interest. The document gives formula and Python examples, but reports no backtest or measured results.

The later proposed version changes the ranking input to active buying and also recommends considering company fundamentals and other technical indicators. These additions are suggestions rather than a fully specified screen: the fundamental filters are placeholders, and the sample ranking calculations do not clearly reproduce the stated auction-based ranking. The article cautions that auction amounts can be noisy and that the approach omits valuation and business information.

Key ideas

• The initial screen combines a large daily range with a large gain during the prior 25 trading days.
• The initial ranking selects five stocks by opening auction amount.
• The article later suggests active buying, fundamental information, and additional technical filters.
• Auction activity can be noisy, and the examples do not fully specify a validated ranking method.
