Robot-Themed Small-Cap Stocks Screened by Turnover and Bollinger Bands

Summary

This stock screen targets companies associated with robotics, limits candidates by turnover and circulating market capitalization, and adds a Bollinger Band price condition. The stated rationale is to use trading activity and company size as preliminary filters, then use the relationship between the closing price and the band levels to select stocks viewed as trading in a relatively stable range. The example also describes ranking candidates by a platform-provided popularity measure.

The document includes formula and Python illustrations, but it does not provide a backtest, measured returns, or evidence that the screen predicts performance. It cautions that Bollinger Bands alone do not establish a stock’s prospects and recommends considering valuation, profitability, and other company information. The examples also contain apparent inconsistencies: the prose says the close lies between the upper and middle bands, while the sample conditions require it to be above the upper band and below the middle band, an impossible ordering under the usual definition. The stated filters and implementation therefore need reconciliation before use.

Key ideas

• The screen combines a robotics theme with turnover and circulating-market-capitalization filters.
• It adds a closing-price condition based on Bollinger Band levels.
• The example proposes ranking qualifying stocks by a popularity measure.
• No backtest or return evidence is provided.
• The stated band condition conflicts with the sample implementation and needs correction.
