Chinese Stock Screen Using Turnover, Float Size, and a Lower Low

Summary

This Chinese equities screening example combines turnover, circulating market value, and a one-day price condition. It describes selecting stocks with turnover between 3% and 12%, circulating value between 1 and 55 hundred million yuan, and a current low below the prior day’s low. The author frames the lower low as a possible trend reversal signal and includes formula and Python examples of the filters.

The note cautions that the screen uses little company financial information and can produce inaccurate selections from a narrow set of inputs. It suggests adding price, volume, and fundamental measures and using a longer observation period to reduce short-term noise. No backtest results or performance evidence are provided, so the proposed reversal interpretation remains unvalidated.

Key ideas

• The screen filters for turnover between 3% and 12%.
• It restricts circulating market value to the stated range of 1 to 55 hundred million yuan.
• A current daily low below the previous daily low is treated as the price signal.
• The note warns that price-only screening omits business and financial conditions.
• It proposes adding volume, price-change, and fundamental measures for broader evaluation.
