Stock Screening with High Amplitude, Rising Averages, and a Recent Limit-Up

Summary

This selection rule looks for stocks with daily price amplitude above one percent, upward movement in a short moving-average relationship, and a limit-up event during the first three trading days of 2021. The article presents the combined conditions as a way to find shares with notable volatility and recent strength, and includes indicator formulas and sample Python screening logic. It does not provide a backtest, selected-stock examples, or performance results, so the evidence is a description of the proposed filter rather than an empirical assessment.

The author characterizes the screen as a possible momentum-oriented approach that may identify fast-moving stocks, while warning that its conditions are restrictive and tied to a specific historical window. It may omit relevant financial information and can behave differently as market conditions and popular themes change. Suggested extensions include adding company financial measures and other technical indicators, then testing and revising the criteria. The examples need careful interpretation: the date-specific limit-up requirement may make the screen unsuitable outside that period, and the moving-average condition as described in the code should be checked against the intended direction of the trend before use.

Key ideas

• The screen combines price amplitude above one percent, an upward moving-average condition, and a limit-up event in early 2021.
• The document describes the conditions as a way to locate volatile stocks with recent strength.
• No backtest or performance evidence is supplied to establish whether the screen is effective.
• The date-specific limit-up filter restricts the strategy's relevance beyond the stated period.
• The author recommends adding financial and technical measures and reassessing the rules across market conditions.
