Shenzhen Stocks Filtered by Amplitude, Control, and Valuation

Summary

This stock screen combines daily price amplitude and a controlling-shareholder measure with valuation limits for Shenzhen main-board shares. It selects stocks with amplitude above 1, a stated control measure above 21, price-to-earnings ratios from 0 to 29.01, and price-to-book ratios from 0 to 3.11. The post presents the rules as a way to combine trading activity and control characteristics with valuation screening, and includes example indicator and Python implementations that rank candidates by a heat measure.

The article offers no backtest, performance data, or evidence that the selected stocks outperform. It notes that valuation ratios can change with market, industry, and company conditions, and that industry risks affect financial results. It suggests adding other screening criteria and reviewing the rules as conditions change. The meaning and scaling of the control measure are not fully explained, and the snippets use differing threshold conventions, so implementation would require checking the underlying data definitions.

Key ideas

• The screen combines amplitude and a controlling-shareholder measure with valuation filters for Shenzhen main-board stocks.
• It sets price-to-earnings and price-to-book ranges as part of the selection rules.
• The post provides example implementations but no backtest or measured results.
• Valuation and industry conditions can change, so the screen may need additional analysis and periodic review.
