A Chinese Stock Screen Using Turnover, Large-Order Flow, and Price

Summary

This Chinese stock-selection note describes a screen combining turnover, price movement, large-order net volume, trading volume, and a price near 18.5. Its central condition selects stocks with turnover between 3% and 12% and a positive product of price change and large-order net volume. The referenced implementations also apply a daily price-change band, a minimum volume, and use the prior day’s turnover; the Python example ranks qualifying stocks by a weight based on average turnover and volume relative to price.

The note cautions that the screen omits other technical and fundamental information and that indicator relevance can change with market conditions. It suggests adding valuation measures and validating or adjusting parameters to reduce overfitting. It supplies no backtest results or evidence that the screen produces returns, and its explanation of price as a valuation measure is not supported with analysis. The rules should be treated as a proposed filter, not a demonstrated strategy.
