Chinese Stock Screen Combining Turnover, a Rising 30-Day Average, and Price Shocks

Summary

This note presents a Chinese stock-selection idea combining three filters: a rising 30-day moving average with price above that average, a high ranking on a volume-ratio measure, and a prior-day opening-price condition associated with the limit-down price. It describes selecting the top 100 stocks by volume ratio and the 100 largest absolute gaps between the prior limit-down price and opening price. The combination is framed as seeking stocks with recent upward trend characteristics despite a sharp price event.

The article flags important ambiguity and risk: a limit-down-related observation may reflect panic or adverse company news, while the moving average only summarizes recent history and capital-flow proxies do not predict subsequent gains. It proposes checking turnover and investigating why the price fell, as well as adding indicators such as MACD. The final stated selection logic is truncated, and the text gives no backtest, performance statistics, or completed rule for combining all three filters.

Key ideas

• The screen pairs a rising 30-day moving average and price above it with volume-ratio ranking.
• It also considers a prior-day gap involving the limit-down price and opening price, using an absolute-difference ranking.
• The article treats the price shock as a possible panic event but warns it may reflect company-specific bad news.
• Recent trend and flow measures can fail to predict future returns.
• The proposed final logic is incomplete, and no performance test is reported.
