Screening Chinese Stocks by Price, Range, Volume, and Opening Gap
Summary
The document proposes a short-term stock screen using four conditions: an amplitude threshold, a specified share price of 18.5 yuan, current volume of at least 10,000 lots, and a higher open. It describes the intended candidates as active stocks with notable price movement and trading volume, and presents both a formula-style version and a Python-oriented implementation. The article also suggests ranking candidates by market popularity and notes that financial condition, industry outlook, and management quality are omitted.
The screen is a simple price-and-volume filter, not a tested strategy. The document supplies no historical returns, benchmark comparison, transaction-cost analysis, or evidence that the conditions predict future performance. Its code descriptions also differ in places: the written amplitude condition and formula use a threshold, while the Python excerpt applies other checks to historical extrema and references fields that are not clearly constructed. The exact interpretation of the opening-gap condition likewise differs between the prose and code. These limits make the example useful as a screening concept, but its implementation and claims require verification before use.
Key ideas
- The proposed screen combines amplitude, a price of 18.5 yuan, volume, and a higher open.
- The article provides formula-style and Python-oriented examples of the filter.
- It recommends adding fundamental and industry information to broaden selection.
- No backtest or evidence of predictive performance is reported.
- Some implementation details do not align clearly with the stated screening rules.
