A-Share Screening with Turnover, KDJ Crossovers, and Bollinger Bands

Summary

This document describes a rule-based A-share stock screen combining a turnover-rate band of 3% to 12%, a newly formed KDJ golden cross, and a close between Bollinger Bands’ middle and upper lines. It frames turnover as a liquidity filter, the crossover as an indication of upward momentum, and the price location as a timing condition. It also gives indicator and Python examples for selecting stocks.

The author cautions that the rules omit company and industry characteristics, so they may select highly speculative stocks with limited growth prospects. Suggested refinements include adding sector leadership, growth or dividend characteristics, and financial measures such as net profit growth and ROE. The document provides no backtest, performance figures, or evidence that the signal predicts returns. Its code examples also appear inconsistent with the stated Bollinger condition, so implementation details should be checked before use.

Key ideas

• The screen limits eligible stocks to a stated turnover-rate range of 3% to 12%.
• A newly formed KDJ golden cross is used as an upward-momentum signal.
• The closing price must lie between the Bollinger middle and upper lines according to the stated rule.
• The method omits company and industry fundamentals and may select speculative stocks.
• The document offers no performance evidence and its code examples should be checked against the described conditions.
