Chinese Stock Screen for Volatility, Fund Control, Size, and Profitability

Summary

This Chinese stock selection proposal screens for stocks with amplitude above 1, signs of major-investor control on the previous day, market capitalization below 10 billion yuan, and no losses. It presents volatility as a way to find active shares, the control condition as a sign of capital interest, and the size and profitability constraints as safeguards. The post also gives example indicator references and Python-style screening logic using earnings measures, historical price changes, and moving averages.

The article does not report backtest results or define all conditions consistently: its code uses amplitude and price-change thresholds that may not match the stated screen, and its indicator references are terse. It acknowledges that the screen may overlook other fundamental considerations, miss some loss-making smaller companies, and fail to anticipate changes in company finances or market value. It suggests adding financial measures such as returns and dividends, along with moving-average or momentum signals, but does not test those refinements.

Key ideas

• The proposed screen combines price amplitude, prior-day major-investor control, a market-cap ceiling, and positive profitability.
• The post frames volatility and investor control as activity signals, while profitability and size are intended as safeguards.
• Its code examples do not fully align with the written criteria, so implementation details need scrutiny.
• The author suggests adding further financial and technical indicators, but provides no performance evidence.
