Screening Chinese Stocks for Reversal Patterns and Recent Limit Ups

Summary

The document describes a short term Chinese equity screen combining three conditions: daily amplitude above one percent, a reversal or engulfing style pattern, and more than two limit up days within the preceding ten days. It presents formula and Python references for calculating the filters and returning matching symbols. The screen is intended to identify volatile stocks with reversal signals and recent market attention.

The accompanying discussion warns that a focus on popular limit up stocks can overlook other candidates, and that limit ups reflect liquidity and speculative sentiment as well as price behavior. It suggests combining the screen with other short term technical and fundamental measures and a longer term trend filter. The document supplies no backtest, transaction cost analysis, or evidence of profitability; definitions and implementation details may also differ across platforms, so the stated signal should be treated as a screening concept rather than a validated strategy.

Key ideas

• The screen requires amplitude above one percent, a reversal pattern, and more than two limit up days in the previous ten days.
• It targets volatile Chinese stocks with recent speculative attention.
• Limit up counts can reflect liquidity and sentiment rather than a company’s underlying value.
• The document recommends adding fundamental, technical, and longer term trend filters.
• No performance evidence or trading cost analysis is provided.
