Screening Small Profitable Stocks After Three Declining Sessions

Summary

The document describes a Chinese A-share screen combining daily price movement, company size, profitability, and recent price weakness. It selects companies with market capitalization no greater than 10 billion yuan, positive net profit, a specified high-to-high price change above 1%, and three consecutive daily declines. The intended idea is to find smaller profitable firms after a short pullback, potentially offering an entry point amid elevated movement.

The post explains the rationale for each filter and provides example formulas and Python-based selection logic. It offers no backtest, performance data, or evidence that the screen predicts profitable rebounds. The author notes that short-term signals can be affected by sentiment and speculation, that the consecutive-decline condition may be misapplied, and that short-term screening can overlook long-run company quality. Suggested refinements include adding valuation and liquidity measures and checking longer-term trends alongside technical and fundamental analysis. The stated filters therefore describe a candidate-selection heuristic, not a validated trading strategy.

Key ideas

• The screen combines a price-movement threshold, a market-cap ceiling, positive net profit, and three consecutive daily declines.
• The post frames recent weakness as a possible adjustment zone but does not demonstrate that a rebound follows.
• It recommends adding valuation, trading-amount, and longer-term trend checks to reduce reliance on short-term signals.
• The method has no reported backtest or performance evidence.
