Screening Chinese Stocks for Volatility, Volume, and Limit-Up Streaks

Summary

This post outlines a Chinese equity screening idea that looks for stocks with an amplitude above 1, current volume above 10,000 lots, a higher open, and non-ST status. It further describes selecting five consecutive limit-up stocks before 10 a.m., treating strong activity and repeated price gains as signs of market interest. A Python example sketches additional filters using recent daily prices, a moving average, and checks intended to identify a five-session limit-up run.

The post cautions that relying heavily on limit-up stocks can encourage impulsive decisions and that the screen omits a broader assessment of technical, company, sector, and market risks. It suggests adding indicators and valuation or growth measures, but provides no backtest, transaction-cost analysis, or evidence that the screen delivers attractive returns. The code and prose also present conditions in different levels of detail, so implementation would require careful validation against the intended rules and market data conventions.

Key ideas

• The proposed screen combines amplitude, current trading volume, a higher open, and non-ST status.
• It focuses on stocks with a sequence of five limit-up sessions and early-day selection.
• The post’s code also sketches a moving-average filter and recent price checks.
• The author warns that a limit-up-focused screen can be impulsive and incomplete.
• No performance testing or transaction-cost analysis is provided.
