Chinese Stock Screen Using Daily Range, Five-Day Average, and Code Prefix

Summary

This screen selects Chinese shares whose daily amplitude exceeds one, whose average price is above the five-day moving average, and whose stock code begins with 60. The document interprets a larger range as a sign of trading activity and price above the short moving average as a possible indication of an uptrend. It describes the code-prefix filter as targeting a particular group of shares, while warning that such stocks may carry higher uncertainty and market risk.

The text offers illustrative Python logic but no backtest, return figures, or evidence that these filters produce an advantage. It also notes that the screen does not itself account for company performance, valuation, industry, or policy conditions. Suggested refinements include adding fundamental and market factors, researching individual company and shareholder circumstances, and controlling position size and stop levels. The selection rules are a starting heuristic; the document does not specify portfolio construction, execution, or exit rules.

Key ideas

• The screen combines daily amplitude above one, price relative to a five-day moving average, and a stock-code prefix condition.
• The proposed rationale links range with activity and the moving-average condition with a possible uptrend.
• The document provides example logic but no tested performance evidence.
• It warns of volatility and company-specific uncertainty and suggests adding other filters and risk controls.
