Chinese Stock Screen Combining Turnover, Float Size, Volume, and Opening Gap

Summary

The document presents a Chinese equity screen with four conditions: turnover between 3% and 12%, circulating market capitalization between 5 billion and 10 billion yuan, current volume above 10,000 lots, and an opening price above the previous close. It frames these filters as a way to combine trading activity, market size, liquidity, and a positive opening gap. Formula and Python examples illustrate the intended selection logic.

The document cautions that the screen ignores company fundamentals and may overvalue activity and liquidity at the expense of other investment considerations. It recommends combining technical and fundamental measures, maintaining portfolio diversification, and revisiting parameter choices. No backtest, historical performance, or benchmark comparison is provided, so the claimed usefulness of the criteria is not demonstrated. The Python example uses mean turnover and market capitalization across the available observations, while the written rule describes threshold conditions; implementation choices should be aligned with the intended screening period. The screen also does not specify entries after selection, exits, or position sizing.
