Screening Chinese Stocks by Listing Age, Amplitude, and Recent Return

Summary

This stock screen selects shares listed for more than one year, with amplitude above 1 and a recent price change between −5% and 2.6%. The stated rationale is to seek stocks with some trading activity while excluding very new listings and limiting the recent-return range. The article also provides a sample data workflow that checks recent daily prices and illustrates a bounded-return filter, but it does not fully implement every stated screening condition.

The article presents no backtest, comparison, or evidence of returns. It cautions that the screen considers price behavior alone and omits company fundamentals, market conditions, and sector rotation. It suggests combining the filter with valuation or technical measures and applying stop levels and position controls. The thresholds are descriptive choices, not demonstrated predictors; the sample code’s market and data selection choices may also affect which stocks are returned.

Key ideas

• The screen uses listing age, price amplitude, and recent percentage change to select stocks.
• It specifies a listing period longer than one year and a recent return range from −5% to 2.6%.
• The stated rationale is to filter out newer listings and constrain recent performance while retaining active stocks.
• The article offers no backtest or evidence that the thresholds predict future returns.
• It notes that fundamentals, market conditions, sector changes, and risk controls are omitted from the basic screen.
