Screening Stocks by Price Range, Volatility, and Trading Heat
Summary
This Chinese-language post outlines an equity screen using daily amplitude above 1, an opening price near the 10-day moving average, and a ranking by stock popularity. Its example implementation treats trading volume as a proxy for popularity and selects the five highest-volume names that meet the price conditions. The stated rationale is that larger price movement may precede a new trend, while an opening near the moving average may indicate a pullback.
The author notes that popularity rankings can be unstable and that the screen omits industry prospects and company quality risks. Suggested additions include valuation and earnings-growth measures, industry analysis, periodic quality checks, and capital-flow data. The post provides formula and Python-style examples, but no backtest, performance evidence, or precise validation of the proposed rationale. It also leaves the meaning of “amplitude above 1” and the definition of popularity dependent on implementation choices.
Key ideas
- The screen combines an amplitude threshold with an opening price within roughly five percent of the 10-day moving average.
- Trading volume is offered as a possible proxy for ranking stocks by popularity.
- The proposed screen is intended to find active stocks near a short-term average during a pullback.
- The author recommends adding company fundamentals, industry context, and capital-flow information.
- Popularity rankings may fluctuate, and the screen may include low-quality or fraudulent companies.
