Screening Established Stocks Above the 250-Day Moving Average

Summary

This stock-selection rule looks for shares with daily amplitude above 1, a listing history longer than one year, and a previous close above the 250-day moving average. The article’s rationale is that a minimum amount of price movement filters out quieter stocks, the listing-age condition excludes newer shares, and a close above the long moving average suggests an established upward trend. It includes a sample implementation outline for filtering Chinese stocks using recent price and moving-average data.

The post notes that the approach relies on price movement and a lagging moving-average signal. It does not account for company fundamentals, industry conditions, or macroeconomic factors, and the long average may result in buying after a move has already advanced. The author suggests adding other technical measures and using stop-loss and take-profit rules. No test results or evidence of the screen’s claimed upside potential are supplied, so the criteria remain a simple screening idea rather than a demonstrated strategy.

Key ideas

• The screen requires amplitude above 1, a listing history longer than one year, and a prior close above the 250-day moving average.
• The moving-average condition is used as a proxy for an established upward trend.
• The article identifies lagging signals and omitted fundamental, industry, and macroeconomic factors as risks.
• It suggests adding technical measures and risk controls but provides no performance evidence.
