Screening Chinese Equities for Volatility, Institutional Activity, and Profits

Summary

This stock screen combines three filters: five-period amplitude above one, a change in an institutional volume-difference measure, and positive earnings for companies below a stated market-value ceiling. It is intended to run after the daily open and to identify smaller listed companies showing price movement, institutional activity, and no reported loss. The article also gives formula references and illustrative Python code, though the code's data fields and conditions do not consistently match the stated market-value filter.

The source characterizes smaller stocks as more exposed to company-specific and policy-driven price changes, and notes that the simple criteria omit other relevant measures. It suggests adding profitability and liquidity checks and using broader data. No backtest, return figures, or validation is supplied, so the screen is a candidate-generation idea rather than evidence of a profitable strategy.

Key ideas

• The screen requires amplitude above one, a changed institutional volume-difference measure, positive earnings, and market value below the stated ceiling.
• It is intended to select stocks after the market opens.
• The article flags elevated risk in smaller companies and the narrowness of its filters.
• The provided example code appears inconsistent with the stated market-value condition.
• No performance test or results are reported.
