Weekly Stock Screening with Turnover, Rising KDJ, and a 30-Week Average

Summary

This document outlines a Chinese equity screen that looks for stocks with turnover between 3% and 12%, a rising KDJ K value, and a weekly close crossing above its 30-week moving average. It presents a platform formula and a Python example. In the Python version, the moving-average condition is checked across the latest two observations to identify a cross, while the KDJ value must rise; turnover is assessed using its mean over the available data.

The rationale is to combine trading activity with momentum and a longer-term trend signal. The document cautions that the approach focuses on technical data, omits company fundamentals, and can be vulnerable to one-week chance variation, broader market moves, and unusual stocks. It suggests adding fundamental checks or further technical conditions. No backtest, performance figures, or comparison with alternative rules are provided, and the described weekly conditions depend on appropriately aggregated weekly data.

Key ideas

• The screen restricts turnover to a range of 3% to 12% and requires the KDJ K value to increase.
• A weekly close crossing above the 30-week moving average supplies the trend condition.
• The Python example checks for a crossing using the latest and prior observations and uses mean turnover.
• The author notes that technical-only selection is exposed to market movements and short-term randomness.
• The document offers no empirical performance evaluation.
