Screening Shenzhen Main Board Stocks by Turnover, Listing Year, and Valuation

Summary

The article describes a Chinese equity screening rule for Shenzhen Main Board stocks. It selects companies with turnover between 3% and 12%, a 2021 listing year, price-to-earnings ratios from 0 to 29.01, and price-to-book ratios from 0 to 3.11. The rationale is to combine moderate trading activity and valuation with a recent listing date, rather than relying on a single screening factor. A Python example is included as a reference, but the article says the corresponding platform formula must be written separately.

The author cautions that these filters cover only a limited set of company characteristics and may miss promising firms or fail to assess future growth. Suggested refinements include adding measures such as PEG and return on equity, considering financial condition, industry outlook, competitiveness, and management, and allowing some premium for higher-quality firms. No historical backtest, return figures, or evidence that the screen produces superior selections is supplied, so the rule is best understood as a starting screen rather than a validated investment strategy.

Key ideas

• The screen combines turnover, listing year, market segment, and valuation filters.
• Its stated thresholds are 3% to 12% turnover, a 2021 listing year, and specified price-to-earnings and price-to-book ranges.
• The article notes that a small set of filters cannot fully assess company value or growth prospects.
• It suggests adding measures such as PEG and return on equity alongside qualitative company and industry analysis.
• No backtest or performance evidence is provided to validate the screening rule.
