Screening Chinese Stocks by Buying Activity, Trend, and Profitability

Summary

This stock selection rule combines three filters: a reported measure of buying activity above 5%, the previous close above the 250-day moving average, and a market capitalization no greater than 10 billion yuan for companies without losses. The document interprets buying activity as a sign of investor interest, the moving-average condition as an uptrend filter, and the profitability and size conditions as business and valuation screens. It provides illustrative pseudocode for combining the filters, though the data retrieval and final stock selection functions are placeholders.

The article gives no backtest or performance evidence. It cautions that the screen depends on market and capital-flow data, cannot guarantee gains, and may miss eligible stocks. It suggests adding valuation, industry, and profitability criteria or testing machine-learning methods, but provides no implementation or validation for those ideas. The buying-activity formula shown in the code may not match the article’s stated threshold directly, so the signal definition should be checked before use.

Key ideas

• The screen requires buying activity above 5%, a previous close above the 250-day moving average, and a qualifying profitable company with market capitalization at or below 10 billion yuan.
• The moving-average condition is intended to favor stocks with positive price trends.
• The provided code is illustrative and leaves data retrieval and stock filtering incomplete.
• The article provides no performance test and warns that the screen may miss opportunities or select stocks that lose value.
