Chinese Stock Selection by Recent Limit-Up Streak and Auction Turnover
Summary
The document presents a Chinese stock-selection rule based on price activity and auction demand. It screens for stocks with a daily range above 1, requires a three-session consecutive limit-up streak on the preceding day, then ranks candidates by the current day’s opening-auction amount and selects the top five. The post explains these conditions as proxies for market activity, investor interest, and capital flows, and includes formula and Python examples.
The author warns that this simple screen emphasizes trading heat while ignoring company fundamentals and industry trends. It may produce weak or unstable selections, and the limited criteria could encourage overfitting. Suggested refinements include adding fundamental, technical, and sector-rotation measures, and considering established leaders with stable earnings and reasonable valuations. The material provides no performance history, backtest, or detailed definition of how the three-session streak is verified. It therefore describes a screening idea, not evidence that the selected stocks will continue rising.
Key ideas
- The screen first requires a daily range above 1 and a three-session limit-up streak on the prior day.
- It ranks qualifying stocks by current opening-auction amount and retains the top five.
- The method treats range and auction turnover as signals of activity and investor attention.
- The post warns that the screen omits fundamentals and industry context and may be overly simple.
- Suggested refinements include adding company, technical, and sector measures, but no performance test is reported.
