A Chinese Stock Screen Using Capital Flows, Valuation, and Opening Gains
Summary
The document describes a stock-selection screen that combines three filters: ranking shares by capital inflow, requiring specified price-to-earnings and price-to-book ranges, and limiting the gain at 9:25 to below a stated threshold. It frames capital flows as a measure of market interest, valuation ratios as indicators of relative pricing, and the early price change as a measure of opening behavior. The screen is presented for Shenzhen main-board stocks.
The article notes that historical screening cannot predict future performance and may omit governance, industry conditions, and other nonfinancial influences. It suggests adding business and sector information or machine-learning forecasts, but does not show a tested implementation or performance evidence. A partial code fragment is included alongside platform navigation and promotional community material; the selection logic is more complete than the code. The stated thresholds are a proposed screening recipe, not demonstrated evidence of profitability or predictive accuracy.
Key ideas
- The screen ranks stocks by capital inflow and filters by valuation ratios and an early-session price gain threshold.
- It applies to Shenzhen main-board shares and describes the factors as measures of flow, valuation, and opening behavior.
- The article cautions that historical filters cannot forecast future returns and may miss company or industry influences.
- It proposes additional business variables and machine-learning forecasts without providing test results or a complete implementation.
