A-Share Screen Using Price Amplitude and Rising KDJ Momentum
Summary
This note outlines an A-share stock screen based on daily price amplitude above 1%, a share price of 18.5 yuan, and a rising K value from the KDJ stochastic indicator. It presents the amplitude threshold as a way to find stocks with notable price movement and the KDJ condition as a short-term directional signal. The article includes indicator-formula and Python examples for expressing related filters.
No performance results or backtest evidence are provided. The note warns that a simple technical screen can select companies with weak fundamentals and that a rising oscillator may reflect a temporary reaction to news or rumors rather than a durable move. It also suggests broadening the analysis with fundamental measures, other indicators, volume, and historical trends. The examples have implementation inconsistencies: the stated price criterion is equality to 18.5 yuan, while the accompanying code does not clearly implement the same complete set of conditions. The screen is therefore best understood as a rough selection idea, not a tested trading system.
Key ideas
- The proposed screen combines amplitude above 1%, a price of 18.5 yuan, and an increasing KDJ K value.
- The note presents amplitude as a measure of price movement and KDJ as a short-term signal.
- A short-term rise in KDJ may result from news or rumors and may not persist.
- The article provides no backtest results and does not establish that the screen is profitable.
- It recommends considering fundamentals, additional indicators, volume, and price history.
