Chinese Stock Screen Using Amplitude, Prior-Day Control, and Price

Summary

This Chinese stock-selection proposal filters for shares with amplitude above 1, an indicator described as prior-day major-player control, and a price of 18.5 yuan. The explanation interprets amplitude as a sign of greater volatility and the control condition as a proxy for large-money flows. It presents the price threshold as a psychological level, but does not substantiate that interpretation.

The document characterizes the approach as short-term and warns that its narrow criteria may produce few candidates, that the price condition does not imply future appreciation, and that short-term trading carries elevated risk. It suggests adding company fundamentals, technical factors, and valuation measures, alongside risk controls. A brief implementation reference is included, but there is no backtest, performance evidence, or validation that the screening conditions predict returns; the method should be treated as an untested heuristic.

Key ideas

• The screen combines amplitude above 1, a prior-day major-player control condition, and a price of 18.5 yuan.
• The document treats amplitude as a volatility cue and the control measure as a proxy for capital flows.
• It warns that the narrow screen may return few stocks and that a price threshold alone does not signal upside.
• The proposal offers no backtest or evidence that its selection rules improve returns.
