Screening Equities by Volatility, Recent Limit-Ups, and Trading-Board Activity

Summary

This Chinese equity screening idea combines a prior-day price-amplitude threshold, appearance on the previous day’s trading activity list, and at least one limit-up event within the preceding month. The document frames these filters as a way to find shares with substantial short-term movement, visible market attention, and recent speculative interest. It includes example formula and Python-style logic for combining the conditions into a single candidate set.

The article cautions that these signals can reflect temporary enthusiasm rather than durable investment quality. A recent limit-up does not guarantee a good opportunity, trading-board records may not represent the whole market, and the filters omit other relevant information. It suggests tracking money flows across multiple periods and incorporating company fundamentals and earnings. No backtest, return series, benchmark, or execution rules are supplied, so the screen describes a hypothesis for finding active stocks rather than demonstrating an effective trading strategy.

Key ideas

• The screen combines a prior-day amplitude filter, prior-day trading-board activity, and a recent limit-up condition.
• The criteria aim to identify volatile stocks that have attracted market attention.
• The document warns that recent limit-ups and trading-board appearances can reflect short-lived speculation.
• It recommends supplementing the filters with flow analysis and company fundamentals, but provides no performance evidence.
