Screening Small Chinese Stocks by Price Range and Revenue Growth

Summary

The proposed Chinese equity screen looks for companies with positive earnings, market capitalization within a stated ceiling, daily price amplitude above a threshold, and revenue growth between two specified years. The article frames the size and revenue conditions as ways to identify smaller businesses with growth potential, while the amplitude condition selects stocks with recent price movement. It suggests broadening the fundamental review with profitability and return measures and considering industry characteristics.

The article warns that concentrating on revenue growth can encourage excessive growth chasing, and that a short-term or narrow set of filters can create overfitting or omit related candidates. It includes formula and Python examples, but the code’s revenue calculation does not clearly substantiate the stated comparison of reported revenues, and its amplitude calculation differs from the prose description. No backtest or other performance evidence is provided, so the screen’s investment value remains unverified.

Key ideas

• The screen combines positive earnings, a market-cap ceiling, price amplitude, and multi-year revenue growth.
• The article presents smaller capitalization and revenue expansion as potential indicators of growth.
• It recommends adding profitability measures and evaluating companies in their industry context.
• The author flags growth chasing, overfitting, and narrow criteria as risks.
• The sample code does not clearly implement the stated revenue comparison, and no performance results are given.
