Screening Stocks with Amplitude, Weekly MACD, and Prior-Day Turnover

Summary

This Chinese stock-selection proposal filters for daily amplitude above 1%, a positive weekly MACD histogram, and prior-day turnover above 8%. Its rationale links amplitude with price movement, a positive weekly histogram with an upward trend, and high turnover with active trading. The article also sketches formula-based and Python implementations, though the examples do not consistently mirror the stated weekly and prior-day conditions.

The proposed refinement adds fundamental checks such as valuation ratios and financial-data analysis. The document cautions that the initial filter relies on a narrow set of indicators and that high turnover can accompany sharp price swings, making risk control relevant. It supplies no backtest, sample results, or evidence that the selection criteria improve returns. The implementation examples are explicitly presented as references requiring adjustment, and the difference between the stated strategy and some code conditions limits reproducibility.

Key ideas

• The stated screen combines amplitude, a positive weekly MACD histogram, and high turnover on the previous day.
• The article interprets these filters as capturing movement, trend, and trading activity.
• It suggests adding valuation and financial analysis to the technical screen.
• High turnover may bring greater price volatility, and risk controls are advised.
• The examples provide no performance validation and do not consistently match the stated conditions.
