A Chinese Stock Screen for Large Moves and Consecutive Limit-Ups

Summary

This Chinese-language post proposes screening stocks for an amplitude above one, at least one daily gain of 10% or more within the previous 25 trading days, and a three-session limit-up sequence ending yesterday. It presents the rules as a way to identify volatile, recently strong stocks, and includes example indicator and Python logic that combines conditions and ranks candidates by volume.

The post warns that relying on short-term strength and consecutive limit-ups can select high-risk stocks while overlooking fundamentals, sector activity, broader market conditions, and macroeconomic factors. It recommends adding those considerations and defining screening rules more clearly. The examples are not a validated backtest: the article gives no performance evidence, and its code snippets do not fully clarify how the stated lookback and three-session condition should be implemented. The screen is therefore a speculative momentum filter with material interpretation and risk limits.

Key ideas

• The screen combines an amplitude threshold, a recent large daily gain, and a three-session limit-up sequence.
• It ranks selected stocks by trading volume in the examples.
• The post identifies dependence on recent price strength as a source of risk.
• It recommends considering fundamentals, sector activity, and market conditions.
• No backtest or performance evidence is provided.
