A Small-Cap Robotics Stock Screen Using Turnover and Auction Volume

Summary

The document proposes screening Chinese shares using amplitude above 1, a ratio based on yesterday’s turnover rate and today’s auction volume relative to yesterday’s volume, robotics-concept membership, and circulating market value below 10 billion yuan. It frames the criteria as a way to identify smaller companies for short-term investment, while recommending that financial, fundamental, and technical measures be added for a broader assessment.

It warns that concept labels do not ensure sound business prospects and that smaller, less liquid shares can carry greater trading risk. The post supplies example code but no backtest or return evidence, and the code does not implement all stated conditions: it checks concept membership and market value, but not the described amplitude and auction-volume ratio. The selection rule should therefore be treated as an incomplete screening illustration rather than a validated strategy.

Key ideas

• The proposed screen combines amplitude, a turnover and auction-volume ratio, robotics-concept membership, and a market-cap ceiling.
• The author describes the approach as a short-term stock-selection screen.
• The document flags weak fundamentals, concept-driven speculation, and poor liquidity as risks.
• The example code omits some of the stated screening conditions, and no performance evidence is provided.
