Chinese Stock Screening by Amplitude, Main-Player Control, and Position Growth

Summary

This stock-selection proposal combines three filters: price amplitude above 1, a signal that large market participants controlled the stock on the previous day, and a current increase in positions exceeding 5%. The author interprets the control and position-growth measures as signs of institutional interest and possible continuation, while using amplitude to exclude quieter, range-bound stocks. The document includes example indicator formulas and a Python-style outline, but does not present a backtest, performance statistics, or evidence that these signals predict returns.

The author identifies two main limitations: the screen omits company fundamentals, and the position-growth threshold may leave few candidates under some market conditions. Suggested refinements include adding financial and industry measures and adjusting the threshold to fit the market. The formula descriptions and sample implementation are references rather than a fully specified, validated system; data definitions and execution rules are not established.

Key ideas

• The screen requires amplitude above 1, prior-day main-player control, and current position growth above 5%.
• The document treats control and position growth as indicators of capital interest and potential price continuation.
• The strategy is technical and does not account for company fundamentals.
• The author suggests adding financial measures and adapting the position-growth threshold to market conditions.
• No backtest or measured trading results are provided.
