Screening Chinese Stocks by Daily Range, Listing Age, and Industry

Summary

This stock-selection note describes a screen for shares with a prior-day price move greater than one percent, more than a year since listing, and a chosen company category, with finance and research-oriented businesses given as examples. The stated rationale is that larger price movement may identify active stocks, listing age may exclude newer firms, and industry selection can focus the search on a particular business type. A code example also filters by industry, ranks by listing age, skips certain flagged names, and collects candidates up to a requested count.

The material is a screening recipe rather than a tested investment strategy: it provides no historical returns, benchmark, or risk-adjusted evidence. The example's range calculation compares consecutive closes, which does not match the usual high-low definition of intraday amplitude and differs from the stated percentage threshold. The note itself flags that industry classification can be affected by economic conditions and policy, and suggests adding price-versus-average or volume filters. It gives no rules for portfolio construction, entry timing, or exits.

Key ideas

• The screen combines a daily price-movement threshold, listing age, and a selected industry category.
• The stated selection rationale links price activity, longer listing history, and business type to candidate filtering.
• The code example ranks candidates by listing age and applies additional exclusions.
• Its price-movement calculation compares consecutive closing prices rather than the day's high and low.
• No backtest or return evidence is presented, and industry choices may be sensitive to economic and policy changes.
