Ranking Chinese Stocks by Trading Activity and Loss-Free History
Summary
The described stock screen ranks shares by the previous day’s combined buy and sell amounts from exchange trading disclosures, then filters for companies with market capitalization below 10 billion yuan and no past losses. The ranking is intended to reflect where trading capital is concentrated, while the size and profitability filters narrow the candidate list. The article also proposes adding financial condition, industry prospects, policy context, and technical or fundamental analysis before making selections.
The document explains the screening logic and names its limitations, but provides no backtest, performance results, or precise definition of the historical loss condition. Its code example is incomplete and does not fully implement the stated profitability and market capitalization filters. The article acknowledges that focusing on activity and size alone can overlook company fundamentals and broader market influences, and that such a screen can include weak candidates or miss promising firms.
Key ideas
- The screen ranks stocks by the prior day’s reported buy and sell amounts.
- It limits candidates to companies below 10 billion yuan in market capitalization and with no past losses.
- Trading activity is treated as a proxy for investor attention, not as a complete measure of future performance.
- The article recommends considering company finances, industry prospects, policy conditions, and further analysis.
- No tested performance evidence is supplied, and the sample code is incomplete.
