A Small-Cap Robot-Themed Equity Screen Using Profitability and Trading Range
Summary
The document outlines a Chinese-equity screen for robot-concept stocks that combines a minimum daily trading-range condition with limits on total and freely tradable market capitalization. It also calls for profitable companies, described in the refined rules as having positive net income in each of the latest four quarters. The intended selection combines a price-range filter, size constraints, a profitability test, and a thematic industry classification.
The text suggests adding broader market and risk controls, and warns that a theme-driven screen can overlook company fundamentals and long-term value. It offers no backtest, return evidence, or systematic evaluation, so the criteria should be treated as an initial screening idea rather than a validated strategy. There is also a mismatch between the stated range calculation and the code examples, as well as ambiguity in how the market-cap limits are represented. Those definitions would need to be standardized before implementation or evaluation.
Key ideas
- The screen combines a daily price-range threshold with market-capitalization limits.
- It restricts the universe to robot-concept firms and companies with positive recent profits.
- The document recommends considering broader market conditions and risk controls.
- No backtest or performance evidence is provided for the proposed selection rules.
- The written criteria and code examples do not define all thresholds consistently.
