Chinese Stock Screen for Rising Lows, Volatility, and Limit-Up Activity

Summary

This note describes a short-term Chinese stock screen using three conditions: amplitude above a stated threshold, a rising-bottom pattern, and more than two limit-up days within a ten-day window. Its stated rationale is to find shares with strong recent price action and favorable market sentiment. The article provides an indicator formula and a Python example, then suggests incorporating fundamentals such as business growth, earnings stability, and cash position, or relaxing the limit-up requirement.

The note argues that the screen is exposed to short-term sentiment shifts and potential downside in stocks with repeated limit-up moves. It supplies no backtest, sample, or performance results. The examples also use different operational definitions: the formula and Python snippet do not clearly establish a consistent interpretation of amplitude or rising bottoms, and the article’s proposed “improved” logic is a set of suggestions rather than a fully specified alternative. These gaps limit reproducibility and make the stated rule a starting point for research rather than a validated strategy.

Key ideas

• The proposed screen combines amplitude, rising lows, and frequent limit-up days.
• The article frames the conditions as a way to identify stocks with strong short-term sentiment.
• It warns that sentiment-driven stocks may carry substantial downside if market mood turns.
• The examples leave key conditions ambiguous, and no empirical performance evidence is supplied.
