Small-Cap Profitable Stocks with Heavy Buying and a Sharp Daily Drop

Summary

This proposed stock screen looks for companies with market capitalization below 10 billion yuan and no losses, alongside a reported increase in buying interest above 5% and a maximum daily decline between 4% and 5%. The rationale is that buying activity may indicate demand while a sharp pullback could offer a rebound opportunity; the profitability and size filters are intended to add a basic quality constraint.

The document acknowledges that the screen focuses on short-term price action and does not assess long-term fundamentals. It suggests adding valuation and technical measures. No backtest or evidence of returns is provided. The example code appears inconsistent with the prose: its filters do not fully implement the stated decline range and profitability condition in the selection function, and its data transformations make the intended signals difficult to verify. These examples should therefore be treated as an illustrative screen rather than a validated trading method.

Key ideas

• The stated screen combines a buying-interest threshold, a daily drawdown range, a small market-cap limit, and profitability.
• The proposed rationale is to identify demand during a sharp pullback.
• The approach emphasizes short-term market data and may overlook longer-term company fundamentals.
• The document provides no performance evidence, and its code does not clearly implement all stated conditions.
