Screening Chinese Stocks by Volatility, Recent Top Lists, and Capital Flows

Summary

This stock screen combines three conditions: prior-day appearance on an exchange top-trading list, a stated price amplitude threshold, and positive large-order net inflow during the current afternoon. The article presents the combination as a way to find active stocks that may attract continued short-term attention. It includes example selection logic and code references, but supplies no backtest results or measured evidence that the conditions predict returns.

The rationale is that larger amplitude reflects short-term movement, top-list inclusion can accompany speculative attention, and net inflow may indicate activity. The article cautions that top-list names can be driven by volatile sentiment, capital-flow data may lag market reactions, and the simple filters can produce noisy or false signals. It suggests adding valuation measures, refining the flow window or inflow-to-outflow criteria, and applying risk controls. The screen is therefore an exploratory short-term selection rule; the document does not establish its profitability or define a complete entry, exit, or sizing plan.

Key ideas

• The screen requires elevated price amplitude, prior-day top-list inclusion, and positive afternoon large-order net inflow.
• The proposed rationale links amplitude and top-list activity to short-term attention, while treating net inflow as an activity signal.
• The article provides example selection logic but no performance results to validate the signal.
• Top-list stocks can be volatile, flow data may lag, and simple filters can generate noise.
• Suggested refinements include valuation inputs, adjusted flow windows, and explicit risk controls.
