Screening Chinese Stocks by Volatility, Float Size, and Listing Age

Summary

This stock-selection screen combines three filters: prior-session price amplitude above 1%, free float no greater than 5.5 billion shares, and more than one year since listing. The accompanying explanation treats amplitude as a way to find active, volatile stocks, the float limit as a small-cap proxy, and listing age as a basic history requirement. It then describes intersecting the filters and selecting a subset ranked by turnover.

The post cautions that these criteria omit company finances and fundamentals, and suggests adding measures such as earnings, assets, growth prospects, and industry conditions. It includes formula and Python examples, but no backtest results or evidence that the screen predicts returns. The stated thresholds and ranking procedure therefore define a candidate universe rather than a validated investment strategy; the treatment of amplitude and listing age also depends on the data conventions used.

Key ideas

• The screen selects stocks using price amplitude, free float, and listing age thresholds.
• The example implementation intersects the filter results and ranks candidates by turnover.
• The post recommends adding financial and business-quality measures to address fundamental risks.
• No performance evidence is provided, so the screen is not demonstrated to generate excess returns.
