Stock Screening with Daily Range, Reversal Patterns, and Popularity Ranking
Summary
The document proposes screening equities for a daily high-to-low range above one percent, a reversal or engulfing-style pattern, and then sorting selected names by a popularity measure. It frames range as a way to find volatile stocks, the pattern as a possible reversal signal, and popularity as a proxy for market attention. Formula and Python examples are included, though the description of popularity and its calculation is not clearly aligned across the examples.
No backtest, return data, or evidence that the screen predicts profitable reversals is presented. The text acknowledges that popularity rankings can overemphasize short-lived market themes and may select heavily promoted stocks rather than companies with strong fundamentals. It suggests supplementing the screen with valuation or technical measures and alternative ranking criteria. The explanation also mentions PE-related risks even though PE is not part of the stated selection rule, so the rationale and implementation warrant careful review before relying on the output.
Key ideas
- The proposed screen requires a daily high-to-low range above one percent and a reversal pattern.
- Selected stocks are sorted by a popularity measure, though its definition is unclear.
- The document supplies formula and Python examples but no performance evaluation.
- Popularity can concentrate the screen in short-lived market themes and does not establish fundamental value.
- The discussion includes PE-related caveats despite PE not appearing in the stated screen.
