Chinese Stock Screen Using Turnover, Three Down Days, and Opening Move

Summary

This Chinese equity screening rule selects stocks with turnover between 3% and 12%, three consecutive bearish sessions, and an auction-period price change between -2% and 5%. It combines trading activity, recent price weakness, and the next session’s opening move, apparently aiming to find weak stocks that might rebound. The article gives formula-style references and a Python example, but the example’s use of close-price changes may not faithfully represent the stated auction-period condition.

The article offers no measured returns, sample period, or comparison against a benchmark. It cautions that the screen pays little attention to company fundamentals and that its simple filters may produce false selections. It suggests adding fundamental information and potentially using machine learning, but provides no validation of those proposed refinements. The setup should therefore be treated as a screening hypothesis rather than evidence of a profitable trading strategy.

Key ideas

• The screen combines turnover of 3%–12%, three bearish sessions, and an auction move from -2% to 5%.
• The rationale is to identify recently weak stocks with possible rebound potential.
• The provided implementation may not measure the stated auction-period move accurately.
• The article reports no backtest results and warns that fundamental risks are not addressed.
