Combining Recent Limit-Up Activity with Positioning and Valuation Filters

Summary

The article outlines a Chinese equity screening idea that combines three signals: a high daily increase in position share, reported institutional buying near lows, and repeated limit-up sessions within a recent window. It interprets these conditions as signs of buying interest, institutional confidence, and market attention. It then proposes adding valuation filters such as price-to-earnings and price-to-book ratios, alongside activity measures such as turnover and trading volume.

The article provides no backtest, transaction-cost analysis, or measured evidence that these signals predict returns. Its example code also appears internally inconsistent: the recent limit-up count is represented through a rolling sum and boolean comparison, while later filters impose both low and high valuation thresholds in sequence. Definitions for the positioning and institutional-buying measures are not established. The article itself cautions that market indicators do not reliably forecast future prices and that short-term volatility can be substantial, so the screen should be treated as an unvalidated hypothesis.

Key ideas

• The proposed screen combines position-share growth, institutional buying, and multiple recent limit-up sessions.
• The article suggests adding valuation and trading-activity filters to refine candidate stocks.
• The screen is presented without backtest results or evidence of predictive performance.
• The example code’s limit-up and valuation filters appear inconsistent with the stated logic.
• The article acknowledges that indicator-based selection can fail and that prices may be volatile.
