Screening Stocks by Range, Prior Limit-Up Status, and Recent Gains

Summary

The article proposes screening stocks for a daily price range above 1%, no limit-up close on the previous day, and a positive gain over the preceding ten days below 35%. It presents the range as a way to find more active shares and treats the prior-day limit-up exclusion as a filter against unusually rapid moves. The gain band is intended to focus on shares that have risen without exceeding the stated ceiling. These are proposed selection rationales, not evidence that the filters predict continued gains.

The article also recommends considering company fundamentals, technical indicators, sector conditions, and macroeconomic context. Its Python example does not clearly implement the described ten-day return condition: it checks the latest daily percentage change and a range calculation using recent prices. No results, backtest, portfolio construction, or exit rules are reported. The suggested screen should therefore be read as a rough candidate-selection idea, with potential downside from chasing recent strength and from relying on a narrow set of price filters.

Key ideas

• The proposed screen requires daily range above 1%, no prior-day limit-up, and a positive ten-day gain below 35%.
• The author presents the filters as a way to find active stocks with recent but bounded gains.
• The accompanying Python example appears to check a daily percentage change rather than the stated ten-day return.
• The article recommends adding fundamental, technical, sector, and macroeconomic context.
• No backtest, performance evidence, or exit rules are supplied.
