Chinese Stock Screen for Recent Limit-Ups and Rising KDJ

Summary

This Chinese equity screening proposal selects stocks with a daily high-low range above one percent, at least one limit-up session in the preceding 25 days, and a rising K value from the KDJ oscillator. The post frames the range as a sign of volatility, a recent limit-up as a notable price event, and a rising K value as improving buying strength. It includes sample indicator logic and Python using daily stock data and a stochastic calculation.

The author recommends placing qualifying stocks in a watch or investment pool, while acknowledging that the screen omits company fundamentals and may be vulnerable to weak market conditions, fast sector rotation, or deteriorating business results. Suggested improvements include adding financial and industry analysis, combining technical measures, and monitoring positions. No backtest, return figures, or comparison with a benchmark is provided. The sample code and formula are implementation references, not demonstrated proof that the conditions predict future gains; limit-up behavior and indicator settings may also vary across stocks and data sources.

Key ideas

• The screen combines a range greater than one percent, a limit-up event within the prior 25 days, and a rising KDJ K value.
• The post treats range as a volatility signal and the recent limit-up as a potentially relevant price event.
• A rising K value is interpreted as strengthening buying pressure.
• The author notes that fundamentals are excluded and identifies market weakness and rapid theme rotation as risks.
• No performance test or evidence of predictive value is reported.
