Screening Chinese Stocks by Amplitude and Institutional Flow

Summary

This stock selection rule screens for shares with amplitude above a threshold, evidence of main-fund control on the previous day, and positive institutional movement. The article frames these conditions as a way to find volatile stocks that attract large investors and institutional interest. It also includes example indicator logic and a Python-style implementation outline.

The post offers no backtest, performance statistics, or validation showing that the signals predict returns. It warns that the screen depends on institutional behavior and historical data, which may not reflect current conditions. Its code examples also contain inconsistencies between the stated selection criteria and the implementation details, so they should not be treated as a verified specification. The article suggests adding trend and company fundamentals, but does not define or test those extensions.

Key ideas

• The screen combines stock amplitude with prior-day main-fund control and positive institutional movement.
• The article presents the filters as a way to identify volatile shares with investor interest.
• No backtest or performance evidence is provided.
• Institutional-flow measures can be stale, and the example implementation may not exactly match the stated rule.
