Screening Chinese Stocks by Recent Return, Market Value, and Range

Summary

The document outlines a Chinese equity screen combining a positive but capped ten-day price return, circulating market capitalization above a stated threshold, and a minimum measure of price movement. It presents the criteria as a way to find larger stocks with recent gains and enough movement for short- to medium-term trading. A formula-style expression and a Python example are offered as implementation references, though the code and written rules do not align cleanly on details such as the amplitude calculation and stock universe.

The page provides no backtest, portfolio construction rules, transaction cost assumptions, or measured results. It cautions that short-term performance and market themes can dominate the picks, while the screen omits company fundamentals and industry context. It suggests combining the signals with financial or industry measures and adjusting parameters, including possible model-based refinement. These are suggestions rather than tested improvements, so the screen should be treated as a preliminary filter whose definitions and implementation require validation.

Key ideas

• The proposed screen selects stocks using recent return, circulating market value, and price movement criteria.
• The stated ten-day return condition is positive and below an upper bound.
• The accompanying formula and Python example appear to differ in how they define and apply the filters.
• The page warns that price-based screening can miss fundamental weakness and can be affected by market themes.
• It recommends testing the filters alongside financial and industry measures, but reports no validation results.
