Stock Screening with Weekly Candles, Price Amplitude, and Market Capitalization
Summary
The document describes a Chinese stock screening rule combining daily price amplitude above a threshold, a positive weekly candle, and circulating market capitalization above a stated floor. It interprets the amplitude as a volatility filter, the weekly candle as a sign of recent upward movement, and market capitalization as a preference for larger companies. A formula example also adds a volume-based ranking step, while the Python illustration checks amplitude, a MACD value, and market capitalization.
The article cautions that a small set of technical and size filters omits company fundamentals and may treat industries unevenly. It suggests adding valuation or growth measures and industry constraints, but supplies no backtest, performance statistics, or validation of the proposed criteria. The examples are references for implementation rather than evidence that the screen is profitable; their differing conditions also mean users should verify that code matches the intended rule.
Key ideas
- The screen combines price amplitude, weekly price direction, and circulating market capitalization.
- The article presents both indicator-formula and Python examples, though their conditions are not fully identical.
- Market capitalization thresholds can affect industries differently.
- The document recommends broader fundamental and industry filters as possible refinements.
- No performance evidence is supplied to establish the screen's effectiveness.
