Chinese Small-Cap Screening with Profitability and Large-Order Flow

Summary

This article proposes screening Chinese stocks for a large recent price range, market capitalization below 10 billion yuan, positive net profit, and a price-change measure combined with net large-order activity that exceeds a threshold. The accompanying formula and Python example also restrict the universe to main-board stocks. The stated rationale is to combine short-term movement, smaller company size, profitability, and trading-flow information.

The article cautions that the screen emphasizes short-term price action and may expose users to substantial losses; it recommends considering longer-term company and industry factors and adding risk controls. It offers implementation examples but no historical performance, validation, or threshold calibration. The formula and code do not consistently operationalize every stated criterion: the formula uses a one-day price rise condition and a change in the high price, while the Python code screens for any price change and does not implement the stated amplitude condition in the same way. The meaning and units of the order-flow threshold also need to be established before use.

Key ideas

• The proposed screen combines price movement, a market-cap ceiling, positive earnings, and large-order net activity.
• The examples restrict selection to main-board stocks.
• The article warns that short-term volatility and small-cap exposure can increase losses.
• The formula and Python example encode some selection conditions differently.
• No backtest results or evidence of profitability are provided.
