A-Share Screening with Turnover, KDJ Crossovers, and Trend Filters

Summary

This document describes a Chinese A-share screening rule that combines turnover, a newly formed KDJ bullish crossover, and a rising-trend condition. Its stated turnover band is 3% to 12%. The referenced formula also checks volume trend and a positive MACD-related condition; the Python example approximates the setup with recent turnover quantiles and closing prices above 30-day and 60-day averages.

The article explains the rationale as using turnover to identify active stocks and technical signals to seek an early stage of an advance. It presents formula and sample implementation details, but provides no backtest results or evidence that the filters predict returns. The code's turnover quantile and KDJ comparison do not necessarily implement the stated crossover and threshold logic exactly. The author notes risks from technical analysis and subjective trend judgments, including late recognition of reversals, and suggests adding fundamentals or machine-learning analysis as possible refinements.

Key ideas

• The screen combines a 3% to 12% turnover band with a fresh bullish KDJ crossover and an advancing-trend condition.
• The formula reference adds volume-trend and positive MACD-related filters.
• The Python example uses turnover quantiles and prices above 30-day and 60-day moving averages as proxies.
• The document provides no performance evidence, and its sample implementation may not match the described signal precisely.
• The author identifies delayed recognition of market changes and mistaken stock selection as risks.
