A-Share Screen Using Turnover and a Fresh KDJ Golden Cross

Summary

This document describes an A-share screening rule that combines current turnover, a newly formed KDJ golden cross, and elevated turnover on the prior day. The stated thresholds are current turnover from 3% to 12% and prior-day turnover above 8%. The accompanying formula and Python example add further filters, including a close at or above the 20-day moving average and a minimum circulating market value; the Python example also uses a turnover quantile condition and rising KDJ values as implementation details.

The article explains that the activity filters aim to find actively traded shares, but it gives no backtest, performance results, or evidence that the signals predict future returns. It cautions that technical indicators can miss company fundamentals and that a single day's turnover may reflect temporary flows. It suggests adding valuation or profitability measures and considering price-volume behavior and market sentiment. The code is a reference implementation, so its data fields and indicator calculations would need validation before use.

Key ideas

• The screen looks for current turnover between 3% and 12%.
• It requires a newly formed KDJ golden cross and prior-day turnover above 8%.
• The reference implementations include additional moving-average and market-value filters.
• The article warns that technical signals may overlook fundamentals and temporary turnover effects.
• It proposes adding fundamental and market-context measures for further analysis.
