A Stock Screen Combining Price, Range, and Recent Limit-Up Activity

Summary

The document outlines an equities screen that selects stocks with a daily range above one percent, a closing price of 18.5 yuan, and at least one limit-up event within the prior 25 trading days. It frames the screen as a way to find volatile, moderately priced stocks with recent momentum, and gives formula-style and Python examples for implementing the filters and sorting candidates by trading value.

The article cautions that the approach may encourage chasing short-term themes and can be exposed to manipulation; recent limit-up activity is not evidence of lasting business strength. It suggests adding financial and industry analysis to assess durability. No backtest results or evidence of predictive returns are supplied. The implementation examples also have inconsistencies between the stated limit-up condition and the code checks, and the exact-price filter is unusually restrictive, so the criteria require verification and careful historical testing before practical use.

Key ideas

• The proposed screen combines daily range, a fixed closing price, and a recent limit-up event.
• The article presents formula and Python examples and proposes sorting candidates by trading value.
• It warns that limit-up based selection can promote chasing and may be vulnerable to manipulation.
• Fundamental and industry context are suggested as additional filters.
• No performance evidence is given, and the example code's limit-up logic should be checked.
