Opening Gap, Daily Return, and Position-Building Stock Screen

Summary

This Chinese-equity screening proposal combines a reported increase in investor positions above 5%, a daily return constrained to a narrow band, and an opening gain below 6%. The post’s description gives the daily-return limits as below 2.6% and above -5%, while its sample logic represents the lower bound as -5.9%; this inconsistency makes the intended threshold unclear. The rationale is to identify stocks with increased positioning while avoiding large opening moves and extreme daily changes.

The article supplies a simplified selection example and a sample data-fetching routine, but no evidence that the conditions predict returns or improve risk-adjusted performance. It notes that market declines can affect qualifying stocks and suggests tightening the return limits, extending the opening-gap threshold, or adding moving averages. The position-building measure is not defined in enough detail to reproduce reliably, and the sample data code is illustrative rather than a complete, validated trading workflow.

Key ideas

• The screen combines position increases above 5%, a constrained daily return, and an opening gain below 6%.\nThe post gives inconsistent lower bounds for the daily return, so the intended rule is ambiguous.\nNo backtest or performance results are reported.\nThe article suggests tighter thresholds and moving-average filters as possible refinements.
