Screening Stocks by Recent Limit-Ups, Positive Earnings, and Trading Activity

Summary

This Chinese-language post describes a stock screen that ranks shares by trading activity, requires positive price-to-earnings ratios, and selects stocks with at least two limit-up sessions in a ten-day window. It interprets high trading activity as a sign of possible market attention and repeated limit-ups as evidence of strong recent performance. The discussion then proposes changing the activity measure to turnover, using rolling P/E below a stated threshold, and considering a short-term return condition.

The post offers qualitative reasoning and lists risks rather than presenting performance data or a backtest. Trading volume may not reliably identify net inflows; a positive P/E alone does not establish fair value; and recent limit-ups do not demonstrate lasting investment merit. The suggested revised screening logic is incomplete: its final short-term price condition is cut off, and it gives no test results or implementation details. The screen is therefore a starting hypothesis, not evidence of a profitable strategy.

Key ideas

• The original screen combines trading activity, positive P/E, and repeated limit-up sessions over ten days.
• Trading activity and limit-up frequency are treated as possible signs of attention and short-term strength.
• The post suggests turnover and rolling P/E as alternative screening measures.
• It cautions that volume, valuation, and recent price strength can all mislead.
• The proposed optimized rule is incomplete, and no backtest evidence is provided.
