Screening Robot-Themed Small-Cap Stocks by Turnover and Opening Gap

Article BigQuant

Summary

This document describes a Chinese A-share selection screen combining robot-industry exposure, small free-float market capitalization, turnover, and the stock’s price change at 9:25. The stated selection logic calls for turnover between 3% and 12%, robot concept membership, free-float capitalization below 10 billion yuan, and a 9:25 gain below 6%. It proposes sorting qualifying stocks by turnover and offers example formulas and data-provider code to illustrate the filtering process.

The article’s final rule and examples are not fully consistent: the final rule changes the opening-gain threshold to below 7%, while the formula and code also use turnover limits that differ from the headline range. The document provides no backtest or performance evidence. It cautions that an opening-gain cap may exclude promising stocks, especially when market conditions are weak, and suggests relaxing the limit or adding measures such as valuation and profitability. The screen is therefore a descriptive idea whose definitions and data fields need reconciliation before evaluation.

Key ideas

  • The proposed screen combines robot concept membership with a small free-float market capitalization.
  • Turnover and the 9:25 price change are used to constrain short-term trading activity and opening strength.
  • The candidates are intended to be sorted by turnover rate.
  • The headline, final rule, formula, and sample code contain conflicting thresholds that require clarification.
  • No performance test is supplied, and the document warns that a strict opening-gain cap can exclude candidates.
