Chinese Stock Screening with Price Range and Recent Limit-Ups

Summary

The document outlines a Chinese stock screen combining three conditions: amplitude above one, a rounded price pattern, and more than two limit-up days in the past 10 days. It interprets amplitude as a way to identify stocks with meaningful trading activity, the rounded pattern as a comparatively gradual movement, and repeated limit-ups as evidence of market attention. A technical formula is included to approximate the pattern and count recent limit-up events, but the article supplies no Python implementation or backtest results.

The author cautions that the screen omits company fundamentals, can depend too heavily on shifting market themes, and may incur excessive trading costs if it encourages frequent turnover. Suggested refinements include adding profitability and leverage measures, adapting the limit-up threshold to market conditions, and combining the screen with technical indicators. These are proposed extensions rather than demonstrated improvements, so the rules should be treated as a hypothesis for further testing.

Key ideas

• The proposed screen combines amplitude, a rounded price pattern, and repeated recent limit-ups.
• The document treats limit-up frequency as a way to identify stocks attracting market attention.
• It warns that the rules omit fundamentals and may select the wrong market theme.
• Trading costs may erode results if the screen leads to excessive turnover.
• The suggested fundamental and technical filters are not supported by reported tests.
