A-Share Screen for Turnover, Opening Price Near the 10-Day Average, and Rising KDJ

Summary

This note describes a short-term A-share screening rule that combines trading activity, opening-price location, and a rising KDJ K value. It selects stocks with turnover between 3% and 12%, an opening price within 5% of the 10-day moving average of closing prices, and a K value higher than its previous reading. The document includes a formula example and Python code that applies these conditions to stock data.

The stated rationale is to capture active stocks whose opening price is near a short-term average while momentum in the KDJ measure is improving. The note gives no backtest or performance evidence, and it does not specify a holding period or an exit rule. It warns that a market decline or a change in fundamentals can invalidate the short-term signal. It suggests considering additional indicators and risk controls, such as stop levels, while adapting indicator weights to market conditions. The example should be validated against the chosen data source and indicator implementation.

Key ideas

• The screen requires turnover between 3% and 12%.
• The opening price must be within 5% of the 10-day closing-price average.
• The KDJ K value must be higher than its prior value.
• The document provides implementation examples but no evidence of returns or predictive accuracy.
• It identifies market declines and changing fundamentals as risks and suggests additional filters and risk controls.
