Chinese Stock Screen Using Amplitude, Institutional Participation, and Positive P/E
Summary
This Chinese-language post describes a daily after-close stock screen based on three filters: amplitude above 1, institutional participation above 30, and a positive price-to-earnings ratio. It presents amplitude as a short-term volatility measure, institutional participation as evidence of institutional involvement, and positive P/E as a basic profitability filter. The intent is to find volatile stocks with institutional interest and positive earnings.
The post gives indicator expressions and illustrative code references, but no backtest, sample definition, holding rule, or return and risk results. It warns that the screen omits broader company considerations such as competitive position, industry conditions, management, and business risks, and suggests adding fundamental analysis and adjusting filters to suit risk preferences. The criteria alone do not establish predictive value, and the institutional-participation label should not be treated as proof of a favorable future outcome.
Key ideas
- The screen runs after each trading day closes.
- It selects stocks with amplitude above 1, institutional participation above 30, and positive P/E.
- The stated rationale combines short-term price movement, institutional involvement, and profitability.
- The post supplies no backtest or evidence that the filters predict future gains.
- It cautions that company fundamentals and business risks require further analysis.
