A-Share Screen Using Turnover, a Fresh KDJ Cross, and Trading Value

Summary

This A-share stock screen looks for market capitalization above one billion, turnover between three and twelve percent, a newly formed KDJ golden cross, and prior-day trading value above sixty million. The article frames turnover and trading value as liquidity or activity filters, while the KDJ cross is intended to identify a developing trend. It includes formula and Python examples, but the code uses a turnover quantile in one place and does not consistently implement the described fresh crossover, so the examples may not exactly match the stated rules.

The author cautions that technical filters omit company fundamentals and industry conditions, and that high trading value can reflect speculative flows rather than business quality. Suggested refinements include adding valuation measures, moving-average confirmation, or market sentiment and sector activity. The document offers no backtest, returns, or evidence that the filters improve selection. Its thresholds and signal definition should therefore be treated as a proposed screen requiring independent testing, with particular attention to data consistency and the timing of the crossover.

Key ideas

• The proposed screen combines market capitalization, turnover, a fresh KDJ golden cross, and prior-day trading value.
• The stated turnover band is three to twelve percent, and the trading-value threshold is sixty million.
• Trading activity can reflect speculation as well as liquidity or investor interest.
• The examples do not consistently implement the stated turnover and crossover rules.
• The article recommends fundamental and additional technical checks but supplies no performance evidence.
