Chinese Stock Screening with Volatility, Volume, and Valuation Filters

Summary

This post describes a Chinese equity screen combining daily price movement, trading activity, and valuation. It selects stocks with amplitude above 1%, current volume above 10,000 lots, a higher open, and Shenzhen main-board listing, while requiring price-to-earnings ratios between zero and 29.01 and price-to-book ratios between zero and 3.11. The accompanying example computes valuation measures from stock and income data, though it does not demonstrate that the implementation matches every stated screening condition.

The author characterizes the valuation bounds as a way to find relatively inexpensive stocks, then notes that the screen omits company financial health, industry context, and technical analysis. Suggested additions include financial and earnings data, sector conditions, and indicators such as moving averages or MACD, alongside risk controls. No historical backtest, performance results, or empirical evidence is provided, so the proposed opportunity and value rationale remain unverified; the post presents a screening concept rather than a validated strategy.

Key ideas

• The screen combines price amplitude, current trading volume, opening behavior, exchange segment, and valuation bounds.
• The stated price-to-earnings and price-to-book ranges are intended to identify relatively low-valued stocks.
• The example code does not establish that all stated conditions are implemented consistently.
• Company finances, industry conditions, and technical signals are cited as missing inputs.
• The post gives no backtest or evidence that the screen is profitable.
