Screening Chinese Stocks by Price Range, Moving Averages, and Limit-Ups

Summary

This stock-selection idea combines three filters: daily amplitude above one, a rising short-term moving-average relationship, and at least two limit-up sessions within the past 500 days. The stated rationale is that amplitude and the moving-average condition seek stocks with favorable recent price behavior, while prior limit-ups are treated as a sign of market attention. The post also gives example implementations in a Chinese indicator language and Python, though they should be checked carefully before use.

The author warns that limit-up frequency can reflect speculation or manipulation and that the screen does not assess long-term prospects. The write-up does not present backtest results, explain how to handle changing limit rules, or establish that the listed conditions predict future returns. Its rationale for using limit-up counts as investor recognition is an interpretation, not demonstrated evidence. The screen is best understood as a simple candidate filter whose definitions and data handling require verification.

Key ideas

• The screen combines daily amplitude, a short-term moving-average relationship, and a historical limit-up count.
• The post interprets repeated limit-ups as a possible sign of market attention.
• The author flags speculation and the omission of long-term trends as risks.
• No backtest evidence is provided, and the sample implementations need verification.
