Screening Chinese Stocks for Activity, High Opens, and Recent Limit-Ups

Summary

This Chinese equity screen looks for stocks with an amplitude above 1, trading volume above 10,000 lots, a higher opening price, and at least one recent limit-up move within roughly the past month. The accompanying formula and Python example describe ways to encode parts of the screen, including a price-move threshold for identifying a recent surge. The examples do not align perfectly with every stated condition, so the implementation details should be checked before use.

The article treats amplitude and volume as signs of activity, and a higher open and recent limit-up as signs of momentum or market attention. It cautions that buying after a sharp rise can mean chasing an already expensive price, and that recent limit-ups alone do not capture fundamentals or broader market conditions. It recommends adding financial, technical, industry, and macroeconomic filters. It provides no performance data or backtest evidence, so the claimed potential is not validated in the document.

Key ideas

• The screen combines high amplitude, substantial volume, a higher open, and a recent limit-up event.
• The article interprets these conditions as signals of activity and recent price strength.
• Its formula and Python example may not implement all stated conditions consistently.
• Recent limit-up behavior can encourage chasing and does not establish fundamental value.
• The article recommends adding financial and market context; it provides no performance results.
