Screening Profitable Small-Cap Stocks with Persistent Large-Order Inflows

Summary

This Chinese-language post describes a stock screen that combines recent buying activity with company and valuation filters. It seeks stocks with a positive daily accumulation measure, positive large-order net flow for several consecutive days, market capitalization below the stated ceiling, and positive earnings. The post also gives price-to-earnings and price-to-book constraints in its final selection logic, with example code illustrating filters for market size and valuation. It offers no backtest results or evidence that the screen predicts returns.

The author notes that apparent accumulation can reflect distribution or short-term trading, and that a small market value or positive earnings alone does not guarantee sound fundamentals. Suggested refinements include adding broader valuation measures and examining multiple time horizons to assess trend. The definitions and data construction of the flow metrics are not explained in detail, and the code’s filters do not fully demonstrate every stated condition. The screen is best read as a candidate-selection concept requiring validation.

Key ideas

• The proposed screen combines positive accumulation, persistent large-order inflows, profitability, and valuation limits.
• The post warns that observed buying may represent selling or short-term turnover rather than lasting demand.
• Market capitalization and positive earnings do not by themselves establish strong fundamentals.
• The flow measures and their predictive value are not validated in the post.
