Robot-Themed Small-Cap Screen Using Range, Auction Gap, and Trend

Summary

This proposed Chinese equity screen looks for robot-concept stocks with an intraday amplitude above 1%, circulating market value below 10 billion, and an opening auction gain between -2% and 5%. The article’s proposed refinement adds a requirement that the closing price be above its 20-day moving average, then suggests further review of valuation, fundamentals, technical measures, and industry conditions. The factors combine a theme classification, size, price range, auction movement, and a short-term trend filter.

The document includes example formulas and Python-style logic but reports no backtest or evidence of returns. It cautions that the screen omits profitability, valuation, broader market conditions, and macroeconomic changes; auction price moves may also be uncertain. The threshold choices are presented without validation, and the code’s market-value units and implementation details may need checking against the data provider. It is best read as a screening hypothesis requiring careful data verification and testing, rather than an established strategy.

Key ideas

• The initial screen combines robot-concept membership, amplitude above 1%, a market-value ceiling, and an auction gain range.
• The suggested refinement adds a close above the 20-day moving average.
• The article recommends adding fundamental, valuation, industry, and market context before acting on candidates.
• No backtest or performance evidence supports the proposed thresholds.
• Auction moves and unexplained data-unit assumptions can lead to incorrect selections.
