Chinese Stock Screening with Amplitude, Control, and Prior Lows

Summary

This Chinese-language article presents a daily stock screen using three conditions: amplitude above 1, a controlling-shareholder measure above 21 in absolute value, and the closing price above the previous day’s low. It provides example implementations in Tonghuashun formula syntax and Python, where stocks meeting all three filters are collected and then sorted by recent price change. The article also proposes adding favorable financial and industry conditions to the screen.

The author cautions that daily technical inputs may miss longer-term price patterns and cyclical influences, while the screen omits fundamentals in its initial form. Suggested refinements include adding financial ratios, examining weekly or monthly data, and adjusting thresholds with historical data analysis. No backtest results or evidence of predictive performance are reported, and the article does not specify how its measures or thresholds were validated.

Key ideas

• The screen selects stocks using amplitude, a controlling-shareholder measure, and the close relative to the prior day’s low.
• The examples apply the three conditions together and sort selected stocks by recent price change.
• The article recommends adding financial and industry information to broaden the assessment.
• It suggests longer price horizons and historical analysis to refine the screen’s inputs and thresholds.
• The document reports no validation results for the proposed selection rules.
