Chinese Stock Screen Using Turnover, Listing Year, and Lower Lows

Summary

This document presents a Chinese equity screen requiring turnover between 3% and 12%, a 2021 listing year, and a current daily low below the previous day’s low. It frames turnover as a liquidity consideration and the lower low as a recent price weakness signal. Example platform rules and Python-oriented guidance are included, although the sample implementation’s handling of listing year and historical data is not fully consistent with the stated screen.

The article provides no backtest, return figures, or evidence that these conditions have predictive value. It warns that the rule emphasizes recent price action and can exclude companies with weak short-term performance but stronger longer-term prospects. It suggests adding valuation measures and adapting the criteria to market conditions, without specifying a validation method. The screen also omits detailed risk controls and fundamental analysis.

Key ideas

• The screen combines a turnover range with a listing-year condition and a lower daily low.
• Turnover is used as a proxy for trading activity, while the lower low captures recent price weakness.
• The examples do not clearly implement every stated condition consistently.
• The article provides no performance evidence and notes the screen’s limited treatment of fundamentals and market context.
