Screening Robot-Themed Stocks by Amplitude, Size, and Trend
Summary
This Chinese-language post outlines an equity screen for robot-concept stocks. It combines a daily high-low amplitude threshold, a circulating market capitalization below 10 billion yuan, and a condition described as the start of a strong upward move. The post offers example formula and Python snippets for expressing the filters, including a moving-average-based trend condition, but does not provide backtest results or a defined holding period.
The author cautions that the trend-start indicator may be unstable, theme popularity can change, and the screen omits company fundamentals. Suggested refinements include combining market and technical signals with fundamental analysis and adding risk controls such as stop losses. The examples are references rather than a fully specified, validated system: data field meanings and units should be checked, and the trend condition is not explained in enough detail to reproduce its intended interpretation confidently. The screen therefore describes a candidate-selection approach, not evidence of profitable performance.
Key ideas
- The screen selects robot-concept stocks with daily amplitude above 1% and circulating capitalization below 10 billion yuan.
- It adds a condition intended to identify the beginning of a strong upward trend.
- Example implementations use a trend indicator alongside concept membership, amplitude, and market capitalization filters.
- The author notes that the trend signal and theme popularity may be unstable, and that fundamentals are omitted.
- Suggested improvements include combining market, technical, and fundamental analysis with explicit risk controls.
