A-Share Breakout Screen Using Weekly Moving-Average Crosses

Summary

This Chinese equity selection rule combines three signals: daily price amplitude above a threshold, a weekly five-period moving average crossing above the ten-period average, and at least one limit-up move within the recent lookback window. The intended rationale is to identify volatile stocks with improving trend and recent market attention. The accompanying example checks for a moving-average crossover and a recent large daily gain, then returns qualifying stock codes.

The post warns that these simple filters can encourage chasing fast-moving stocks and do not account well for company fundamentals or industry conditions. It suggests combining technical signals with fundamental measures, sector analysis, and trading activity, and managing follow-on risk through diversification and profit-taking. No backtest results or evidence of predictive performance are provided. The explanation also describes the moving-average condition as weekly, while the sample calculation uses rolling averages of daily closes, leaving the implementation frequency unclear.

Key ideas

• The screen requires elevated price amplitude, a five-period average crossing above a ten-period average, and a recent limit-up move.
• The stated aim is to combine volatility, trend direction, and recent trading attention.
• The rule may encourage chasing and does not incorporate fundamentals or sector context.
• The post recommends broader analysis and risk controls but provides no performance evidence.
• The written weekly signal and the daily-price example do not clearly match in frequency.
