Screening Stocks by Amplitude, Top-List Activity, and Weekly Trend

Summary

This stock screen selects shares with amplitude above 1, an appearance on the previous day’s market top-trading list, and a weekly price crossing above its 30-week moving average. The post treats amplitude as a sign of short-term movement, top-list activity as evidence of unusual capital flows, and the moving-average cross as a longer-term trend filter. It includes example indicator and Python-style logic for combining the three conditions.

The author notes that market reversals can undermine the approach and that a weekly signal may arrive slowly. Proposed additions include volume, valuation, other chart timeframes, capital-flow measures, and sector context. The post supplies no backtest, return series, or empirical support for the claim that the selected shares offer investment value. Its code examples also express the weekly trend condition in differing ways, so the implementation details warrant careful review.

Key ideas

• The screen combines amplitude above 1, previous-day top-list appearance, and a weekly cross above the 30-week moving average.
• The three filters are intended to capture short-term movement, unusual trading activity, and a longer trend.
• The author identifies reversal risk and lag from the weekly signal.
• Volume, valuation, multiple timeframes, and sector context are suggested as additional filters.
• The post provides no performance test or return evidence.
