Screening Chinese Stocks by Market Value, Profitability, and Price Range

Summary

This stock-selection proposal combines a market capitalization ceiling, positive profitability, a minimum amplitude condition, and a concentration measure described as being below a threshold. Its discussion frames the screen as a mix of volatility, company size, and financial health, while warning that it may encourage chasing price moves, miss long-term growth prospects, and rely on lagging financial data. It suggests combining technical and fundamental inputs and reviewing the rules as conditions change.

The examples do not implement the proposal consistently. The screening formula compares operating revenue with net profit and uses an amplitude threshold, while the Python example also checks price movement over a longer interval and historical high-low range; neither clearly implements the stated concentration condition. The document gives no backtest results or evidence that the rules identify superior investments. The stated selection logic and example code therefore require clarification and validation before they can be treated as a reproducible strategy.

Key ideas

• The proposal filters stocks using size, profitability, price amplitude, and a concentration measure.
• The author identifies risks from price chasing, overlooked growth, and delayed financial data.
• The formula and Python example use conditions that do not consistently match the stated screen.
• The suggested improvement is to combine technical and fundamental information.
• No performance evidence or backtest results are provided.
