Screening Small-Cap Robot Stocks by Amplitude and Fund Flow
Summary
This post describes a Chinese equity screening idea that selects stocks associated with the robotics concept, with circulating market capitalization below 10 billion yuan and daily amplitude above 1%, then ranks candidates by a fund-strength or net-flow measure. It includes illustrative indicator-formula and Python examples. The stated rationale is to combine a price-range condition, a thematic classification, a size filter, and a measure of money flow; suggested extensions include valuation indicators, adjustable stock-pool filters, and stop-loss controls.
The examples do not establish that the screen earns positive returns, and no performance evaluation is provided. The post itself identifies transaction costs, slippage, drawdowns, and the instability of historical technical signals as risks. Its suggested formula and code use different descriptions of the flow filter, so the precise signal needs clarification before implementation. The theme and size conditions can also concentrate exposure, while the general suggestions to add valuation and risk filters do not specify testable rules.
Key ideas
- The screen combines a robotics theme, a market-capitalization ceiling, daily amplitude, and a ranking by money flow.
- The post offers formula and Python illustrations but no backtest or evidence of profitability.
- Transaction costs, slippage, drawdowns, and changing market behavior are identified as risks.
- The fund-flow condition is represented differently across the description and examples, so implementation details need clarification.
- Valuation filters, adjustable stock-pool rules, and loss controls are proposed as possible refinements.
