Screening Stocks for Institutional Activity and Recent Accumulation

Summary

This post describes a Chinese equity screen combining positive institutional activity, a threshold for the day's increase in holdings, and a 2021 date filter. It interprets the holding-change measure as a sign of buying interest and positive institutional activity as evidence of institutional demand. Its proposed refinement substitutes a turnover threshold and a minimum institutional ownership value as more specific measures.

The post cautions that these conditions do not guarantee future gains: recent buying may not continue, institutional activity can change, and a historical date window says little about subsequent markets. It includes an example data workflow, but does not provide screening results, a backtest, or evidence that the proposed thresholds have predictive value. The explanation also contains inconsistent threshold references, and the sample calculation depends on data fields whose meaning is not established in the text. Treat the screen as an illustrative hypothesis requiring data validation and out-of-sample testing.

Key ideas

• The original screen combines a daily holding-increase share, positive institutional activity, and a 2021 time window.
• The post proposes turnover and institutional ownership value as alternative measures.
• Recent accumulation and institutional buying do not ensure future price gains.
• The date filter may not represent current market conditions.
• No results or backtest establish the screen's predictive value, and the example data fields need validation.
