Screening 2021 IPOs by Turnover and Company Type
Summary
This stock screen selects companies that listed in 2021, have turnover between 3% and 12%, and meet a chosen company-type category, such as state-owned, private, or high-tech. The accompanying Python example filters listing-year and turnover-related fields, then applies code-prefix rules for some company types or calls an external check for high-tech status. The article suggests that pairing trading activity with company classification may narrow a recent-IPO universe.
No historical performance or selection results are provided. The article cautions that company type alone does not determine future prospects and that the screen leaves out much of a company’s value, including financial condition, industry outlook, competitiveness, management, and growth. It suggests adding measures such as valuation and return on equity. The implementation also appears to rely on proxy rules for enterprise classification and does not show how turnover is measured over time, so both data definitions and category mappings require validation before use.
Key ideas
- The screen combines a 2021 listing year, a turnover range of 3% to 12%, and a selected company type.
- The code uses listing and turnover-related fields, with stock-code prefixes as proxies for some company categories.
- The article offers no backtest or evidence of returns from the screen.
- It recommends considering financial, valuation, management, and industry factors alongside company type.
