Screening Chinese Stocks by Range, Trading Activity, Gaps, and Institutional Buying

Summary

This Chinese stock-selection post describes screening for shares with an intraday range above a threshold, high current trading volume, a higher opening price, and signs of institutional buying. Its rationale is that active trading and a strong open may indicate market interest, while institutional purchases may be interpreted as support. The post also suggests broadening the screen with technical measures such as RSI, valuation and earnings indicators, sector trends, and overall market conditions.

The article warns that relying on institutional activity can create information asymmetry and that the screen omits fundamentals and other technical signals. It includes a Python example that applies several filters, including a long moving-average condition and unusually high turnover, but the code does not clearly implement the stated institutional-buying criterion and contains selection logic that is difficult to reconcile with the described rules. No backtest results or performance evidence are given, so the screen should be treated as a proposal rather than a validated strategy.

Key ideas

• The stated screen combines large price range, high current volume, a higher open, and institutional buying.
• The post interprets these conditions as signs of activity and potential institutional interest.
• Suggested additions include technical indicators, valuation measures, earnings growth, and market context.
• The author notes risks from relying on institutional activity and omitting other information.
• The example code does not clearly match every stated screening condition, and no performance results are reported.
