Screening Shanghai-Listed Stocks by Amplitude and Rising KDJ Momentum
Summary
This stock-selection screen combines daily amplitude above one percent, a code prefix associated with Shanghai-listed shares, and an upward trend in the K component of the KDJ indicator. The rationale is to focus on stocks showing both elevated short-term movement and strengthening technical momentum. The page provides formula and Python examples: one checks the amplitude and market-prefix conditions, while the KDJ condition uses a positive slope or a positive smoothed change over a recent interval.
No backtest, performance statistics, or evidence of predictive value is provided. The document notes that technical indicators cannot capture a stock’s full investment merits and risks, and that parameter choices can change results. It also cautions that a short-term trend screen may miss company fundamentals and broader industry direction. The examples leave room for interpretation about how KDJ growth should be calculated, so implementation details would need to be fixed before evaluating the screen.
Key ideas
- The screen requires amplitude above one percent and a stock code beginning with 60.
- It selects for a rising KDJ K value as a sign of strengthening short-term momentum.
- The document presents alternative formula and Python descriptions of the KDJ growth condition.
- It warns that technical signals may overlook fundamentals and that parameter choices affect selection.
- No backtest or evidence of investment performance is included.
