Robot-Themed A-Share Screen Using KDJ Crossovers and Market Capitalization

Summary

This Chinese-language post proposes screening A-shares for a daily price range above 1%, a newly formed KDJ crossover, a robot-related classification, and circulating market value below 10 billion yuan. It presents the screen as a candidate-stock selection rule and discusses combining volatility, a momentum-style technical signal, an industry theme, and company size. Formula and Python examples are included, although the examples do not implement the stated concept filter consistently: one uses a price-change condition over a rolling window, while the other checks whether a name contains the robot term.

The post offers no backtest results or evidence that the combined conditions predict returns. It acknowledges that the screen omits fundamental analysis, that thematic interest may fluctuate, and that small capitalization does not itself imply growth. It suggests adding valuation and financial measures and testing the strategy. The stated threshold and code details should be checked carefully before use, especially because the described indicator trigger and implementation may differ.

Key ideas

• The proposed screen combines a daily range threshold, a recent KDJ crossover, robot-theme membership, and a market-cap ceiling.
• The examples describe screening rules but implement the robot-theme condition inconsistently.
• The post provides no backtest evidence for the screen's return potential.
• It identifies missing fundamental analysis and risks tied to thematic sentiment and small capitalization.
• It suggests adding company financial measures and validating the rules through testing.
