Screening Chinese Robot Stocks by Range, Prior Limit-Up Status, and Float Value

Summary

This document describes a Chinese equity screen for robot-related companies with daily amplitude above 1, no limit-up close on the previous day, and circulating market value below 10 billion yuan. It frames amplitude as a way to find active shares, the prior-day condition as a way to avoid stocks in a rapid rise, and the industry and size filters as a focus on smaller growth companies.

The post recommends adding fundamental and technical measures, including profitability, earnings growth, debt, and ownership considerations, then forming a diversified portfolio. It provides no performance data or empirical test of the proposed screen, and the accompanying sample code does not clearly implement the stated prior-day limit-up condition or robot-sector classification. The method is therefore a screening idea rather than evidence of a profitable strategy; its reliance on volatility, sector labels, and company size may miss other relevant risks and fundamentals.

Key ideas

• The screen combines daily amplitude above 1 with a prior-day non-limit-up condition.
• It restricts candidates to robot-related companies with circulating market value below 10 billion yuan.
• The post suggests broadening the screen with financial and technical measures.
• No backtest results are presented, and the sample code does not clearly match every stated filter.
