Screening Shenzhen Main Board Stocks After a Limit-Down Open

Summary

This stock-selection recipe combines a current amplitude threshold with a previous-session opening-auction condition and basic valuation filters. It targets Shenzhen Main Board shares whose prior 9:15 matching price was at the limit-down level, with price-to-earnings values between zero and 29.01 and price-to-book values between zero and 3.11. The screen also requires amplitude above 1; the article says the resulting candidates can be ranked by stock popularity and limited to the first requested number.

The stated rationale is to combine volatility, market sentiment, and valuation. The author notes that strict valuation cutoffs may exclude high-growth companies and that price multiples alone do not reveal financial risk. Technical measures such as KDJ or MACD are suggested as additions. The article includes formula and code references, but supplies no backtest, trading rules for entries or exits, or evidence of returns. Its screening criteria therefore do not establish investment quality or profitability.

Key ideas

• The screen combines amplitude above 1 with a previous-session 9:15 matching price at the limit-down level.
• It restricts candidates to Shenzhen Main Board stocks within stated price-to-earnings and price-to-book ranges.
• The article describes the filters as a mix of volatility, market sentiment, and valuation criteria.
• Valuation multiples can omit high-growth firms and do not capture all financial risks.
• No performance evidence or complete entry and exit method is supplied.
