Screening Chinese Stocks by Turnover, Listing Year, and Prior-Day Top-Trader Listings

Summary

This stock screen selects Chinese equities with turnover between 3% and 12%, an IPO year of 2021, and an appearance on the prior day’s publicly reported top-trader list. The article frames that list as a possible indicator of market attention or sentiment and presents the rules as a straightforward, actionable filter.

The post also includes sample selection code and suggests adding fundamental or technical filters, such as valuation, leverage, or momentum indicators. It flags several limitations: the screen omits other company and market factors, and top-trader activity may reflect short-term institutional trading and be volatile. Although the code adds a positive recent-price-change condition, the written final selection rule does not include that extra filter. No backtest, return analysis, transaction-cost assumptions, or evidence of predictive performance is provided, so the screen should be understood as a candidate selection rule rather than a demonstrated strategy.

Key ideas

• The stated screen combines a 3%–12% turnover band, a 2021 listing year, and a prior-day top-trader-list appearance.
• The article treats top-trader-list data as a possible measure of attention or market sentiment.
• The sample code adds a positive recent price-change check that is absent from the written final rule.
• The author notes that the screen ignores other factors and may be affected by short-term trading activity.
• No backtest or performance evidence is provided.
