Chinese Stock Screening by Price Range, Listing Age, and Float Size

Summary

This Chinese equity screening proposal combines three filters: daily price range above 1%, more than one year since listing, and circulating shares no greater than 5.5 billion. The text presents price range as a way to find active stocks, listing age as a rough stability filter, and float size as a small-cap proxy. It also gives formula references and a Python example intended to implement the selection process.

The article offers no backtest, performance figures, or comparison with a benchmark. Its rationale is qualitative, and the author notes that a float-size threshold is relative and that the screen may miss promising stocks. The example code also diverges from the stated criteria: it first selects stocks by market capitalization and requires each recent observation to pass the range threshold, so it should not be treated as a verified implementation. The suggested extensions include valuation and technical indicators, and replacing an absolute float threshold with float as a proportion of total shares.

Key ideas

• The screen combines a daily range above 1%, a listing age over one year, and a circulating-share ceiling of 5.5 billion.
• The author interprets price range as a proxy for activity and listing age as a rough stability filter.
• The article provides formula references and sample Python, but the code does not fully match the stated screening logic.
• No empirical performance evidence is reported, and the author cautions that the screen may omit potential candidates.
• Possible extensions include valuation and technical measures or a relative measure of float size.
