Screening Chinese Robot Stocks by Range, Market Cap, and Exclusions
Summary
The document describes a short-term Chinese A-share screening rule. It selects stocks with a daily high-to-low range above 1%, membership in the robotics concept group, and circulating market capitalization below 10 billion yuan. It also excludes Beijing-listed A shares and stocks already included in a specified index or constituent set, then ranks the remaining names by heat. The article presents the logic in prose and gives example indicator and Python implementations.
The rationale offered is to filter for trading liquidity and spread holdings, but the rule does not define a complete entry, exit, or position-sizing method. It provides no backtest, performance data, or evidence that the filters predict returns. The author notes that the screen does not assess company results or prospects and suggests adding quality considerations and explicit profit-taking and stop-loss rules. The implementation examples also leave some operational details unclear, including the precise meaning of the reversal or “wrap” condition.
Key ideas
- The screen combines a greater-than-1% high-to-low range with a robotics concept classification and a market-cap ceiling of 10 billion yuan.
- It excludes Beijing-listed A shares and stocks already present in a specified constituent set.
- Remaining candidates are ranked by heat, though the article provides no evidence that this ranking improves returns.
- The rule omits company quality, forward prospects, and explicit trade management, so it is not a complete strategy.
