Chinese Stock Screen Using Recent Gains, Limit-Up Activity, and Range

Summary

This Chinese A-share screening idea combines a positive 10-day return below 35%, recent limit-up activity, and a daily range condition. The accompanying discussion frames it as a way to find stocks with recent strength for short- to medium-term observation. It cautions that short-term price action and limit-up frequency can bring high volatility, while the screen omits company fundamentals and longer-term trends. It suggests adding fundamental, macroeconomic, industry, policy, and research inputs, then applying risk controls.

The document includes indicator-formula and Python examples, but their conditions do not consistently implement the stated screen. The prose specifies more than two limit-ups in ten days, while the formula counts a different high-price comparison and allows at most two occurrences; its range calculations also differ from the stated amplitude threshold. The Python example uses an unreliable rolling expression for limit-up counts and checks conditions in a way that may not yield a single-date screen. No backtest results or performance evidence are provided, so the idea should be treated as a screening concept rather than a validated strategy.

Key ideas

• The proposed screen targets stocks with a positive 10-day return below 35% and recent limit-up activity.
• The article describes the approach as a short- to medium-term way to identify recently strong stocks.
• Frequent limit-ups may select volatile stocks, and short-term filters can miss longer-term trends and fundamentals.
• The formula and Python examples do not consistently match the prose conditions.
• The document provides no performance results to validate the screen.
