Stock Screening with Price Range and Rising KDJ
Summary
The document describes a stock screen combining daily amplitude above 1, a price below 20, and a positive change in the KDJ K value. It presents the KDJ increase as a way to identify upward price momentum, then recommends checking it alongside other technical indicators, fundamental data, and the broader market trend.
It warns that indicator-based screening can overfit historical data, miss fundamental changes, and inherit weaknesses in KDJ. Formula and Python examples are included, but their expressions are inconsistent with parts of the written rule: the formula uses a different price threshold and reverses the KDJ change calculation, while the Python example uses an amplitude definition that differs from the formula. No backtest results or evidence of predictive performance are provided, so the screen is a hypothesis rather than a validated strategy.
Key ideas
- The proposed screen requires amplitude above 1 and a closing price below 20.
- It also selects stocks with a positive change in the KDJ K indicator.
- The document recommends combining technical signals with fundamental data and market direction.
- Historical indicator screens can overfit and may fail when market fundamentals change.
- The code examples do not consistently implement the stated screening rules.
