Screening Chinese Stocks by Amplitude, K-Line Value, and Turnover

Summary

This article describes a Chinese equity screen requiring price amplitude above 1%, a field labeled KONGB below 20, and turnover between 2% and 9%. It presents the combination as a way to find stocks with notable price movement, a low reading on the named field, and a specified level of trading activity. It includes reference formulas and Python-style selection logic, including sorting selected stocks by turnover.

The post characterizes the criteria as a technical and liquidity filter, then recommends adding technical patterns, fundamentals, financial data, and industry context for broader analysis. It cautions that the method omits company fundamentals and that turnover thresholds are subjective; stale turnover data could also make selections less timely. The document does not define KONGB clearly, reconcile differences between the formula and Python amplitude calculations, or provide backtest results. It therefore offers a screening recipe, not evidence that the conditions predict returns or identify high-quality stocks.

Key ideas

• The screen combines amplitude above 1%, KONGB below 20, and turnover between 2% and 9%.
• The article treats amplitude as a volatility filter and turnover as an activity and liquidity filter.
• Its reference implementations show how to combine the conditions and rank selected stocks by turnover.
• The post warns that the criteria omit fundamentals and that the turnover range is subjective.
• No backtest or evidence of predictive performance is supplied.
