Screening Stocks by Price Amplitude, Moving Averages, and Market Capitalization

Summary

The document describes a Chinese stock screening rule that combines daily price amplitude, a short-term moving-average condition, and a minimum company size based on market capitalization. Its stated goal is to find stocks with notable price movement and rising price action while filtering out smaller firms. It also suggests adding industry data and financial statement measures to make the selection process more complete.

The article provides indicator logic and a sample Python outline, but no historical performance results or testing method. The descriptions of the moving-average condition are not fully consistent: the formula and code compare closing prices and moving averages in different ways. The meaning and units of the amplitude and capitalization thresholds also depend on the data source and implementation. Market capitalization is not a definitive measure of company quality, and the screen does not address portfolio sizing, transaction costs, or broader market risk.

Key ideas

• The screen combines price amplitude, a moving-average condition, and a market-capitalization threshold.
• It uses recent price behavior as a proxy for upward momentum.
• The article recommends adding industry and financial statement data for broader evaluation.
• Market capitalization alone does not establish a company’s value or future potential.
• The sample logic is not supported by reported backtest results, and its moving-average descriptions differ.
