Revising a Chinese Equity Growth Screen with Relative Size and Growth Filters

Summary

This update log describes changes to a Chinese equity screening expression. The initial filters included a trailing price-to-earnings ceiling and a minimum listing age. The author then replaces a fixed floating-market-capitalization threshold with a percentile-rank condition and adjusts the thresholds for year-over-year net-profit and operating-revenue growth. The text records that performance dropped after some threshold changes and notes that ranking by relative size was chosen instead of using a fixed number.

The page lists two backtest periods, one from 2018 through 2022 and another from 2023 through 2025, but provides no return figures, benchmark, portfolio construction details, or other evaluation statistics. It is therefore evidence of iterative rule changes rather than enough information to assess robustness or performance. The growth and size criteria are presented as evolving choices, without explanation of how the final filters were selected or validated.

Key ideas

• The screen begins with a valuation ceiling and a minimum listing history.
• A relative floating-market-capitalization rank replaces a fixed capitalization cutoff.
• The update log changes net-profit and operating-revenue growth thresholds.
• The author reports performance deterioration after some changes but gives no quantified results.
• Two backtest date ranges are listed without statistics or validation details.
