Chinese Stock Screen Combining Buying Activity, Losing Streaks, and Limit-Ups

Summary

This Chinese A-share screening idea combines three conditions: buying activity above a stated threshold, three consecutive down sessions, and at least two limit-up moves within the prior 500 days. The post interprets the combination as seeking heavily watched stocks that have recently weakened while attracting buying, and then proposes adding profitability, growth, and return-rank filters.

The article warns that the screen focuses on short-term price behavior, can return few stocks, and may lose effectiveness as market conditions change. It supplies sample data-query code, but does not report a backtest, realized returns, or a validated implementation. The accompanying discussion is conceptual, and the data examples do not establish that the proposed filters reliably measure institutional buying or future upside.

Key ideas

• The initial screen combines elevated buying activity, three down days, and multiple limit-up events over a 500-day lookback.
• The post suggests adding profitability, growth, and return rankings to broaden the selection criteria.
• A strict combination of conditions may produce few candidates.
• The author cautions that short-term price signals may not reflect company value and may be sensitive to market regime.
