Chinese Stock Screen for Volatility, Weekly Trend, and Recent Limit-Ups

Summary

This Chinese A-share screening strategy combines three technical conditions: daily amplitude above the stated threshold, the latest close moving above a five-session average, and a recent limit-up event within roughly one month. The accompanying explanation treats volatility, short-term trend, and evidence of strong recent price action as ways to identify stocks attracting market attention. It suggests adding company fundamentals, sector context, trading volume, and capital flows to make selection more comprehensive.

The document includes a sample Python implementation, but its details do not fully match the prose: it compares the close with a five-session average rather than explicitly testing a crossover, and its recent-high check is only a proxy for a limit-up event. It provides no backtest, performance figures, or risk controls. The stated caveat is that a technical screen can overlook business quality and may chase short-lived market themes; historical patterns may also fail as conditions change.

Key ideas

• The screen combines daily amplitude, price relative to a five-session moving average, and a recent limit-up event.
• It frames recent limit-ups as a possible signal of market attention and strength.
• The sample implementation may not precisely implement the described crossover and limit-up conditions.
• The author recommends adding fundamentals, sector context, volume, and capital-flow information.
• The document provides no evidence of backtested returns and warns that technical signals can miss fundamental risks.
