Screening Stocks by Intraday Range, Trading Volume, and Opening Strength

Summary

This post describes a stock screen that selects shares with a sizable daily price range, high current trading volume, and a higher opening price, then ranks candidates by market attention. The suggested interpretation is that price movement and trading activity can identify stocks attracting interest. A proposed refinement would rank candidates using a combined fundamental and technical score, with industry context also considered.

The post warns that relying on price, volume, and popularity can leave out company fundamentals and broader market conditions, and that attention may shift with sentiment. It includes a code outline for ranking stocks, but the scoring function is left empty, so the combined ranking method is not operationally specified. No backtest, return evidence, or risk-adjusted evaluation is given. The screen is therefore a set of selection ideas rather than a demonstrated strategy, and its thresholds and implementation details would need independent definition and testing.

Key ideas

• The initial screen combines price range, current volume, a higher open, and a popularity ranking.
• The post proposes adding industry, fundamental, and technical information to improve selection.
• Popularity-based ranking may be unstable as market sentiment changes.
• The example’s combined scoring function is unspecified, so the refined screen cannot be reproduced as described.
• The post provides no evidence that the rules generate profitable or risk-adjusted returns.
