Combining Robot-Theme, Valuation, and Profitability Filters for Stock Selection

Summary

This document proposes a Chinese stock-selection screen focused on companies associated with the robotics theme. Its initial criteria are daily amplitude above 1%, circulating market capitalization below 10 billion yuan, and return on equity above 15% in each of five consecutive years. An expanded version also requires positive net profit growth and gross margin, then suggests weighting the indicators into a composite score and ranking eligible stocks. The article includes example indicator logic and a Python-style implementation, but presents no portfolio construction details or performance test.

The stated rationale is to combine market activity, company size, and a multi-year profitability record. The document acknowledges that historical financial measures cannot predict future company or industry conditions and that ROE alone does not capture overall profitability or cash flow. It suggests considering macroeconomic and industry conditions, additional financial metrics, and technical analysis. These are general proposals rather than a defined or validated model: the weighting method is unspecified, and the article supplies no evidence that the screen improves returns or controls risk.

Key ideas

• The initial screen combines robotics-theme membership, daily amplitude, market capitalization, and five years of ROE history.
• The expanded screen adds positive net profit growth and gross margin criteria.
• The article proposes ranking qualifying stocks with a weighted composite score but does not specify the weights.
• It warns that historical financial indicators omit important company, industry, and macroeconomic risks.
• No backtest or investment performance evidence is reported.
