Chinese Stock Screening by Turnover, Listing Prefix, and Market Attention

Summary

This proposed screen starts with Chinese stocks whose codes begin with 60 and whose turnover rate is between 3% and 12%, then says to rank qualifying names by individual-stock attention or popularity. The accompanying explanation treats attention as a proxy for market expectations, but the example Python implementation instead sorts by turnover rate and also applies a positive-earnings-multiple check. That mismatch means the example does not faithfully implement the stated popularity ranking.

The article warns that attention can lag, reflect sentiment, and lead to selecting already overheated stocks or missing emerging opportunities. It suggests combining attention with financial and technical measures, or predicting attention with machine learning. No backtest, definition of the attention measure, or evidence of predictive value is supplied, so the screen remains a heuristic proposal.

Key ideas

• The stated screen applies a 3%–12% turnover band to stocks with codes beginning with 60.
• The proposed ranking variable is stock attention, though the example code ranks by turnover instead.
• The article describes attention as potentially sentiment-driven and lagging.
• No backtest or predictive evidence is provided, and the attention measure is not defined.
