Screening Shanghai-Listed Stocks by Range and Float Market Value

Summary

The document describes a stock screen combining daily price range, exchange code, and circulating market value. It selects stocks whose codes begin with 60, whose high-to-low range exceeds 1% of the opening price, and whose circulating market value meets a stated minimum. It also suggests ranking qualifying stocks by market value and provides example formulas for two platforms.

The rationale offered is that the range condition finds more volatile stocks, while a larger float value may favor more established companies. These are claims rather than demonstrated results: the document presents no performance test, benchmark, holding period, or trading rules. The stated market-value threshold also conflicts with the example code's numeric threshold, so the implementation should be checked before use. The author notes that the screen may increase risk, miss other candidates, and benefit from additional market, financial, or industry filters.

Key ideas

• The screen requires a stock code beginning with 60 and a high-to-low range above 1% of the open.
• It adds a minimum circulating market value and proposes sorting qualifying stocks by that measure.
• The document gives platform-specific examples, but its stated value threshold does not match the code example.
• The screen is not accompanied by backtest evidence, and its volatility filter may increase risk.
