Screening Stocks by Daily Range, Recent Limit-Up Moves, and Positive Earnings

Summary

This stock-screening proposal selects shares whose daily high-to-low range exceeds one percent, that have had at least one limit-up session in the prior twenty-five days, and that have a positive price-to-earnings ratio. The stated rationale is to combine active price movement, recent strong market interest, and positive earnings. The article offers indicator and Python examples, then discusses possible refinements such as adding financial measures, considering industry and macro conditions, capping volatility, and defining stop-loss and profit-taking rules.

The source itself cautions that a positive PE ratio alone says little about overall company quality, that high-range stocks carry greater risk, and that past observations may not predict future returns. The examples also appear inconsistent with the stated lookback rule: the Python conditions combine the range, limit-up, and PE tests on the same row rather than clearly checking for a limit-up during the preceding window, and the indicator expression is not fully explained. No backtest results or evidence of profitability are provided.

Key ideas

• The proposed screen combines a daily range above one percent, a recent limit-up event, and positive PE.
• The rationale associates larger ranges with opportunity and recent limit-ups with market interest, but neither guarantees future gains.
• Positive earnings do not replace broader measures of financial quality or valuation.
• The article recommends accounting for market and industry conditions, bounding volatility, and managing exits.
• The code examples do not clearly implement the stated prior twenty-five-day limit-up condition.
