China Stock Screen Using Turnover, Price Change, and Large-Order Flow

Summary

This stock-selection method screens for shares with turnover between 3% and 12%, market capitalization of at least 200 million yuan, and a positive product of the daily price change and a measure of large-order net flow. The article also presents an implementation that ranks qualifying stocks by a weight based on average turnover and volume relative to price, then selects up to a chosen number of names.

The rationale is to find actively traded, larger companies with signs of buying interest. The article cautions that relying on quantitative signals can neglect fundamental value and may concentrate picks in popular sectors or stocks. It suggests combining the screen with return, valuation, or growth measures and loosening constraints if too few companies qualify. No historical performance or risk statistics are provided, and the code examples use related but not perfectly identical expressions of the screen, so implementation details warrant checking.
