Shenzhen Main Board Stock Screen Using Valuation Ratios and Amplitude

Summary

This post outlines a historical screen for Shenzhen Main Board stocks in 2021. It selects shares with amplitude above 1, a price-to-earnings ratio from 0 to 29.01, and a price-to-book ratio from 0 to 3.11. The approach combines a basic activity filter with two valuation measures, and the article characterizes it as a simple fundamental screen rather than a strategy built on complex technical calculations.

The accompanying Python example checks the valuation ranges and Shenzhen location, but explicitly omits the amplitude condition, so it does not fully implement the stated rule. The post notes that fundamentals can change, investor preferences affect results, and reliance on only two ratios leaves out other financial information. It suggests combining additional fundamentals with technical, industry, and market analysis. No backtest, return data, or evidence of predictive value is given, so the criteria should be read as a dated screening example rather than a validated investment method.

Key ideas

• The historical screen targets Shenzhen Main Board stocks during 2021.
• It requires amplitude above 1 and price-to-earnings and price-to-book ratios within specified ranges.
• The sample Python implementation filters valuation and location but leaves out the amplitude condition.
• The post cautions that valuation inputs change and that two ratios alone omit important company information.
• No performance results are supplied, and the screen is not presented as a tested trading strategy.
