Shenzhen Stock Screen Using Price, Amplitude, PE, and PB

Summary

The document describes a screening rule for Shenzhen main-board stocks that combines a daily amplitude threshold above 1% with a closing price below 20, positive price-to-earnings below 29.01, and positive price-to-book below 3.11. It includes formula and Python examples; the Python version calculates amplitude from the day's high and low relative to the previous close, then filters by board, price, and valuation ratios. It also sorts selected stocks by trading volume.

The article recommends considering company fundamentals, trend indicators, and risk controls alongside the screen, but it does not define those additions or show backtest results. PE and PB alone do not capture business prospects or financial condition, and the meaning of the stated K-line threshold is not fully explained beyond the code's closing-price filter. The rule is therefore a candidate filter for further evaluation, not a validated strategy or a complete trading plan.

Key ideas

• The screen combines daily amplitude above 1% with a closing price below 20.
• It restricts candidates to Shenzhen main-board stocks with PE between zero and 29.01 and PB between zero and 3.11.
• The Python example ranks qualifying stocks by trading volume.
• The document recommends broader fundamental review, trend analysis, and risk controls but provides no performance evidence.
