Screening Equities by Price Range, Listing Age, and a Rising 30-Day Average

Summary

This Chinese-language note describes a stock screen using three filters: amplitude above 1, more than one year since listing, and a rising 30-day moving average. It presents amplitude as a way to find stocks with some activity, the listing-age rule as a way to avoid the volatility of newly listed shares, and the moving average direction as a recent upward-trend signal. It also gives an indicator expression for comparing the current 30-day average with its prior value and illustrative selection code.

The note provides no backtest, performance results, or evidence that the filters improve returns. It warns that price and technical data alone omit company fundamentals, industry conditions, and macroeconomic factors, and that selected stocks may be volatile. It suggests adding other indicators and using exits such as profit targets or stop losses. The description does not fully specify how amplitude is calculated, and the code example includes market-universe restrictions that may not match the stated general screen.

Key ideas

• The screen requires amplitude above 1 and a listing age greater than one year.
• It selects stocks whose 30-day moving average is higher than its prior value.
• The note offers no performance evidence and identifies omitted fundamental and macroeconomic factors as risks.
• Additional indicators and explicit exit rules are suggested as possible enhancements.
