Screening Shenzhen Main Board Stocks by Range, Turnover, and Valuation

Summary

This stock screen selects Shenzhen main-board shares using daily price amplitude, a turnover-rate band, and limits on price-to-earnings and price-to-book ratios. The accompanying discussion frames the filters as a combination of volatility, market activity, and valuation. It cautions that valuation ratios alone cannot establish intrinsic value and that amplitude and turnover do not reliably forecast market direction. It suggests adding further technical and fundamental measures and using stop losses and diversification.

The document gives no backtest, return history, benchmark, or evidence that the selection rules are profitable. Its prose describes the screen, while the included example code adds a closing-price condition that is not part of the stated final selection logic, so implementations may not match the described rule. The thresholds are a screening recipe rather than a validated investment strategy, and the note does not specify rebalancing, position sizing, or transaction-cost assumptions.

Key ideas

• The screen combines price amplitude, turnover, market listing venue, and valuation thresholds.
• The document warns that price-to-earnings and price-to-book ratios do not fully capture business value.
• Amplitude and turnover filters do not by themselves predict future market direction.
• The accompanying code includes a closing-price filter absent from the stated final screening rules.
• No performance evidence or trading implementation details are provided.
