Selecting High-Amplitude, Liquid Chinese Stocks Before 10 a.m.

Summary

The proposed screen seeks five non-ST Chinese stocks before 10:00 using price amplitude above 1 and prior-day trading value above 60 million, then ranks candidates by current percentage change. The article describes these conditions as a way to focus on liquid, volatile stocks showing strong early movement. Its Python illustration uses historical price data for some filters and current-market data for the top-five ranking, leaving the timing and alignment of the combined conditions unclear.

The article cautions that the selection depends on market volatility and that non-ST status alone does not establish strong fundamentals. It suggests adding company performance measures and managing positions for short-term trading. No indicator formula or backtest results are provided, and the sample code does not clearly establish that selected stocks are limit-up stocks as its prose claims. The method is therefore an underspecified screening idea, not evidence of a reliable strategy.

Key ideas

• The screen combines amplitude above 1, prior-day trading value above 60 million, and exclusion of ST stocks.
• It selects five candidates before 10:00 based on early percentage gains.
• The article links volatility and liquidity to short-term selection but provides no performance validation.
• The sample code's data timing and claimed limit-up condition are unclear.
