Chinese Stock Screen Using Price Range, Listing Age, and Auction Turnover

Summary

This Chinese equity screen selects stocks with a price range greater than one, more than three years since listing, and prior-day auction turnover above 0.26. It presents range as a proxy for attention and trading activity, while the listing-age condition is intended to avoid the greater instability associated with newly listed companies. Auction turnover is treated as a sign of short-term market activity that might support trading opportunities.

The post cautions that the rules omit company fundamentals, that active trading does not establish longer-term upside, and that the age filter may exclude promising newer stocks. It recommends combining the screen with fundamental measures and weighting criteria. No backtest or performance evidence is supplied. The sample code contains calculations and thresholds that appear inconsistent with the written rules, including a turnover calculation that should be checked; this makes independent validation of the implemented screen especially important.

Key ideas

• The screen requires a price range above one and a listing history longer than three years.
• It also requires prior-day auction turnover above 0.26.
• The author treats range and auction activity as proxies for attention and short-term market activity.
• The post warns that the screen ignores fundamentals and may overlook newly listed stocks.
• It supplies no performance results, and its code example should be checked against the stated filters.
