A Chinese Stock Screen Using MACD, Moving Averages, and Turnover

Summary

The post proposes screening Chinese stocks for MACD above zero, upward separation of short moving averages, and a prior-day auction turnover condition. It presents the combination as a way to select for positive momentum while using trading activity as a measure of market attention. It also sketches MACD and moving-average calculations and offers example Python-style screening logic, with placeholders for fundamental filters and additional conditions.

The explanation warns that short-term turnover can fluctuate, technical criteria omit company fundamentals, and too many filters may overfit or leave very few candidates. It suggests considering fundamentals, reviewing factor weights, and simplifying the screen. However, the supplied turnover formula appears to calculate a volume-based ratio from price changes rather than auction turnover, and the code leaves some filters undefined. No backtest results or evidence of profitability are provided, so the proposed rules should be treated as an illustrative screen rather than a validated strategy.

Key ideas

• The proposed screen combines positive MACD, upward moving-average alignment, and a prior-day activity threshold.
• The post uses technical indicators to characterize momentum and turnover as a proxy for market attention.
• The sample code leaves fundamental and weighting conditions incomplete.
• The turnover formula shown may not measure auction turnover as described.
• The author notes risks from missing fundamentals, unstable short-term signals, and overfitting.
