Screening Chinese Stocks by Moving-Average Convergence and Prior Limit-Ups

Summary

This proposed A-share screen combines three conditions: at least five moving averages converge, the opening price is near the 10-day average, and the stock has hit the daily limit at least twice in the past 500 days. The accompanying rationale treats average convergence as a sign of price consolidation and prior limit-ups as evidence of strong past demand. It also suggests adding company size, profitability, debt, and longer-term performance criteria, then spreading capital across several stocks.

The post provides only a qualitative rationale and an incomplete code example; it does not report a backtest, define how close averages must be to count as converged, or specify what “near” the 10-day average means. Its sample code uses only three moving averages and does not clearly implement the stated five-average or limit-up conditions. These gaps make the screen a starting hypothesis rather than a validated trading rule. The proposed fundamental filters and diversification are suggestions, not demonstrated improvements.

Key ideas

• The screen combines moving-average convergence, proximity of the open to the 10-day average, and repeated past limit-up moves.
• The post interprets converging averages as consolidation and previous limit-ups as evidence of strong past price action.
• It proposes adding fundamental filters and spreading investments across stocks to address company-specific and sector risks.
• No performance evidence is provided, and the code does not fully implement the stated selection rules.
