Chinese Stock Screen: Volatility, Recent Limit-Up, and Institutional Flow

Summary

This Chinese A-share screening idea combines three conditions: daily price amplitude above one percent, at least one limit-up event during the preceding 25 days, and a positive institutional-direction measure. The accompanying discussion treats volatility as a sign of trading activity, a recent limit-up as evidence of market interest, and positive institutional flow as a possible indication of buying pressure. It also sketches implementations using technical conditions and moving averages of a proxy for money direction.

The note warns that weak company results or a poor market can undermine the selected stocks, and that institutional inflows do not establish sound risk controls. It suggests adding indicators or fundamental analysis and limiting single-stock exposure while diversifying. The rule is presented without a backtest, benchmark, or measured evidence. The example formulas also differ in how they define a recent limit-up and institutional flow, so the screen’s precise implementation and reliability remain uncertain.

Key ideas

• The screen requires price amplitude above one percent, a recent limit-up event, and positive institutional direction.
• The rationale combines price volatility, evidence of market interest, and a proxy for institutional buying pressure.
• The document identifies company weakness and unfavorable market conditions as risks to the selection.
• It recommends adding analysis and controlling position concentration, but reports no backtest results.
• The example implementations do not define all screening conditions consistently.
