Chinese Stock Screen Using Volatility, Control, and Limit-Up Frequency
Summary
The document proposes a short-term screen for Chinese stocks using three signals: daily amplitude greater than 1, a prior-day “main-force control” measure, and more than two limit-up days within ten days. It frames amplitude and the control measure as indicators of short-term movement, while repeated limit-ups are treated as evidence of market attention and possible continued strength. Formula references and a Python example are included, but the meaning and exact construction of the control measure are not clearly established, and parts of the example do not transparently match the stated conditions.
No backtest, returns, or comparative evidence is provided. The document notes that the approach emphasizes technical and popularity signals, ignores company fundamentals, and carries elevated short-term trading risk. It recommends combining additional valuation, fundamental, and market information and managing position risk, but does not test these proposed changes.
Key ideas
- The proposed screen combines amplitude, a prior-day control measure, and frequent limit-up moves.
- Repeated limit-up sessions are interpreted as a sign of market attention and possible momentum.
- The document includes formula and Python references, but leaves parts of the signal definitions and implementation unclear.
- No performance evidence is reported, and the author highlights short-term risk and missing fundamental data.
