Screening Chinese Stocks by Volatility, Recent Limit-Ups, and Moving Average

Summary

This document describes a Chinese stock watchlist screen using three technical conditions: daily amplitude above 1%, at least one limit-up event in the prior 25 days, and the current average price above its five-day moving average. It interprets amplitude as a sign of volatility, a recent limit-up as evidence of market interest, and price above the short moving average as a sign of strength. It includes indicator formula and Python examples, though the code’s stated conditions do not consistently implement the full 25-day lookback logic.

The document warns that adverse company performance or a weak market can undermine the screen, and that the method omits fundamental and valuation analysis. It suggests adding financial measures, other technical indicators, position limits, and portfolio diversification. No backtest, performance data, or evidence is provided to establish that these filters predict returns; the explanations are rationale rather than demonstrated results.

Key ideas

• The screen combines amplitude above 1%, a limit-up event within the prior 25 days, and price above its five-day moving average.
• The document treats recent limit-ups and price strength as signals of market interest and trend.
• The provided code examples may not faithfully implement the complete lookback condition.
• The method lacks demonstrated performance evidence and omits company fundamentals and valuation.
• Suggested safeguards include adding financial filters, limiting single-stock exposure, and diversifying.
