Screening Chinese Stocks by Turnover and Three-Day Declines

Summary

This document describes a Chinese equity screen for 2021. It selects stocks with turnover rates between 3% and 12% and three consecutive declining sessions. The stated rationale is to combine a liquidity or activity filter with recent price weakness, which may identify speculative stocks sensitive to market sentiment. It provides example implementations in technical-analysis formulas and Python, though the code's conditions do not cleanly match the prose in every respect.

The author notes that the screen omits company fundamentals and industry context, and that restricting the period to 2021 can exclude stocks or market conditions outside that window. Suggested refinements include adding profitability, growth, and industry factors, and using a broader time range. No backtest results or evidence of predictive performance are reported, so the selection rule should be treated as a simple screening hypothesis rather than a validated strategy.

Key ideas

• The screen combines a turnover range of 3% to 12% with three consecutive declining sessions.
• The proposed rationale is to pair trading activity with short-term price weakness.
• The document warns that the rule ignores fundamentals and industry differences.
• The examples are implementation references and do not establish predictive performance.
