Chinese Stock Screening with Volatility, Institutional Flow, and Control

Summary

This Chinese stock-screening proposal combines three signals: amplitude above 1, a change in an institutional net-volume measure, and a reported control indicator above 21%. It says to select qualifying shares after the market opens. The rationale is that larger amplitude indicates active price movement, the institutional measure may reflect buying interest, and the control reading may indicate concentrated buying pressure. Together, the filters are presented as a way to find potentially promising lower-priced or newer stocks.

The document provides indicator expressions and a Python sketch, but no backtest, performance results, or validation of the data definitions. It warns that high-amplitude stocks can be volatile and that the source and reliability of the control and institutional-flow measures need checking. It suggests adding valuation, earnings, and volume measures, then ranking or weighting indicators. The sample code also relies on undefined or platform-specific fields, so it is not a complete, directly reproducible implementation.

Key ideas

• The proposed screen requires amplitude above 1, a change in an institutional volume-difference measure, and a control reading above 21%.
• Selection is intended to run after the market opens.
• The rationale links volatility, institutional activity, and concentrated buying with potential upside, but the document supplies no evidence that these signals predict returns.
• The source and calculation of the flow and control data should be verified, and the strategy carries substantial volatility risk.
• The author suggests combining the filters with valuation, earnings, and trading-volume measures.
