Robot-Themed Small-Cap Screening with Volatility and Recent Gains

Summary

This Chinese A-share screening idea combines a large daily trading range, at least one sharp daily gain within the recent 25-session window, a robotics-related classification, and a circulating market value below 10 billion yuan. The post presents these filters as a way to focus on volatile, recently strong, smaller companies in a popular theme. It includes example indicator logic and Python-style code, though the examples do not align perfectly with the stated lookback and thresholds, so implementation details need checking before use.

The author warns that the screen omits company fundamentals and industry-specific analysis, may be overfit, and could be so restrictive that it excludes promising candidates. Suggested improvements include adding financial and industry data, accounting for broader market conditions, validating the rules, and relaxing filters where appropriate. No backtest results or performance evidence are supplied, so the idea is a screening hypothesis rather than a demonstrated strategy.

Key ideas

• The screen combines daily range, a recent large gain, robotics classification, and a small circulating market value.
• The post frames the filters as a short-term volatility and momentum screen.
• Its code examples may not exactly implement the written rules, so the conditions require verification.
• The author identifies missing fundamental analysis, overfitting, and overly restrictive filters as risks.
• No performance evidence is provided, and the screen requires validation before practical use.
