Chinese Stock Screening with Amplitude, Control, and Position Changes
Summary
The document describes a Chinese stock screen requiring daily amplitude above 1, a controlling-shareholder measure above 21, and a position-change ratio above 5%. It presents the three conditions as a way to find stocks with notable price movement and reported accumulation, then suggests holding selected names and adjusting positions over time. It also gives example implementations for a screening platform and Python, though these are references rather than a complete tested trading system.
The article warns that the approach may encourage chasing rising prices or selling into declines, and that it omits company fundamentals. It proposes adding market activity and fund-flow measures, valuation and profitability indicators, and other technical indicators. No backtest, performance data, universe definition, or precise validation of the screening thresholds is supplied, so the stated potential for growth should not be treated as demonstrated. The thresholds and data fields may also depend on the source platform’s definitions.
Key ideas
- The screen combines daily amplitude, a controlling-shareholder measure, and position-change ratio thresholds.
- It provides example platform and Python approaches for applying the three filters.
- The article identifies momentum-chasing risk and the omission of fundamental information.
- It suggests supplementing the screen with market-flow, fundamental, and technical measures.
- No empirical performance evidence or threshold validation is presented.
