Screening Chinese Stocks by Volatility, Trading Activity, and Float Value

Summary

This note describes a short-term Chinese equity screen combining three conditions: prior-day price amplitude above 1%, appearance on the previous day’s trading-activity ranking list, and circulating market value between 5 billion and 10 billion yuan. Its rationale is to focus on relatively volatile stocks with evidence of unusual trading and a bounded company size. The article gives example indicator and Python implementations for combining the filters and sorting candidates by price.

The author warns that market reversals can undermine the setup, that company size does not ensure earnings stability, and that ranking-list activity can bring sharp price swings. Suggested refinements include adding valuation measures and reviewing business quality. The post provides no performance results or empirical validation, and its code examples use dated data references, so the screen is best understood as a proposed selection rule rather than an established strategy.

Key ideas

• The screen requires price amplitude above 1%, prior-day ranking-list activity, and circulating value from 5 billion to 10 billion yuan.
• The author interprets ranking-list appearance as a possible sign of unusual capital flows.
• The examples intersect the three conditions to produce a candidate list.
• The post gives no backtest evidence and notes that volatility and market reversals can create losses.
