Screening Small A-Shares for KDJ Crossovers and Positive Earnings

Summary

The proposed A-share screen combines turnover between 3% and 12%, market capitalization below 10 billion yuan, nonnegative earnings, and a newly formed KDJ golden cross. The crossover condition is presented as a way to find potential opportunities among companies that also pass basic size and profitability filters. The document includes a formula and a Python example for retrieving financial, market-capitalization, and indicator data, but reports no backtest, trade outcomes, or other evidence that the screen is profitable.

The author identifies reliance on KDJ as a weakness because indicator signals can be unstable or inaccurate as market and stock conditions change. Suggested refinements include adding other technical indicators and considering company fundamentals and market behavior more broadly. The examples should be treated cautiously: their data fields and date ranges are implementation sketches, and the article does not explain how to resolve discrepancies between formula conditions and the narrative. It also gives no rules for sizing positions, timing exits, or managing risk after selection.

Key ideas

• The screen combines a turnover band, a market-cap ceiling, and a profitability filter with a recent KDJ golden cross.
• The document supplies formula and Python illustrations but no performance evidence.
• It warns that KDJ signals may be unstable or inaccurate across changing conditions.
• The author suggests supplementing the signal with other technical indicators and fundamental information.
• Position sizing, exits, and post-selection risk management are not specified.
