Chinese Stock Screen Using Amplitude, Control Changes, and RSI

Summary

This Chinese-language post describes a stock-selection screen using three conditions: daily amplitude above 1, a daily controlling-shareholder measure whose absolute change exceeds 21, and RSI below 65. It frames amplitude and the control measure as indicators of volatility and capital activity, while RSI is used to filter for stocks considered relatively low. Formula and Python examples illustrate how the conditions can be combined to select stocks.

The post cautions that the screen omits company fundamentals, broader market conditions, and other technical indicators. It notes that RSI can produce false signals and that relying on a narrow set of conditions may encourage overfitting. Suggested extensions include market activity and capital-flow measures, fundamental metrics such as earnings and returns, and additional indicators. No backtest, performance evidence, precise validation method, or evidence that the proposed additions improve results is provided; the screen is presented as a simple starting point rather than a validated strategy.

Key ideas

• The screen selects stocks using amplitude, a daily controlling-shareholder change measure, and RSI.
• The stated thresholds are amplitude above 1, absolute control-measure change above 21, and RSI below 65.
• The examples show how the conditions can be combined in a stock selector.
• The post warns that RSI can give false signals and that a simple screen may be overfit.
• It proposes adding market, capital-flow, fundamental, and technical variables, without reporting validation results.
