Screening Stocks for Revenue Growth, Listing History, and Price Amplitude

Summary

This proposed Chinese stock screen combines daily price amplitude above 1, a listing history longer than three years, and revenue for 2021 exceeding 2018 revenue by a ratio greater than 1.1. The article presents the revenue comparison as a basic growth check, the listing-age filter as a way to avoid newer stocks, and higher amplitude as a possible sign of trading interest. Its sample data logic also applies exchange and listing-code exclusions.

The post provides no backtest or performance results, and its Python example is not a full implementation of the stated screen: the daily-data checks add extra high-price conditions, while the code shown does not clearly apply the claimed listing-age criterion as a unified query. The author notes that revenue growth does not guarantee value growth and that short-term activity says little about long-term prospects. Net profit, margins, and further research are suggested as additional checks.

Key ideas

• The stated screen requires amplitude above 1, more than three years since listing, and 2021-to-2018 revenue greater than 1.1.
• The post treats revenue growth as a company-growth signal and amplitude as a possible indicator of investor attention.
• The sample Python logic includes extra daily high-price checks, so it does not exactly match the stated screen.
• Revenue growth alone does not establish business quality or future stock performance.
• No backtest or performance evidence is provided.
