Screening Robot-Theme Stocks by Volatility, Auction Turnover, and Float Size

Summary

This post proposes a Chinese equity screen combining a daily price-amplitude threshold, a top-five ranking by auction amount, membership in a robotics theme, and circulating market capitalization below 10 billion yuan. It presents the ranking and size filters as ways to focus on actively auctioned, smaller thematic stocks, while suggesting that high amplitude may identify volatile candidates. It also flags risks from company profitability, broader market and macroeconomic conditions, and policy exposure in the robotics sector.

The post offers example indicator references and Python-style pseudocode, but the examples do not clearly implement the stated screen: the amplitude condition is represented as an amount field, auction ranking and concept membership are placeholders, and units or data availability are not established. It supplies no backtest, execution assumptions, or evidence that the selection rule earns returns. The strategy is therefore best read as a screening idea requiring data checks and validation, rather than a demonstrated trading system.

Key ideas

• The proposed screen combines price amplitude, auction-amount ranking, robotics-theme membership, and a circulating-market-cap threshold.
• The post argues that auction activity may help avoid selecting stocks with little trading activity.
• It identifies profitability, macroeconomic conditions, and industry policy as risks.
• The example code and indicator references do not reliably demonstrate the stated conditions.
• No performance evidence or execution analysis is provided.
