Screening Chinese Stocks for Volatility, Limit-Ups, and Revenue Growth
Summary
The post proposes a Chinese equity screen combining daily price movement, recent limit-up activity, and revenue growth. Its stated selection logic looks for amplitude above one, more than two limit-up days within ten days, and 2021 revenue greater than 1.1 times 2018 revenue. The accompanying discussion interprets these conditions as seeking active, popular stocks with growing sales. It also suggests considering market conditions, management stability, and business growth when reviewing candidates.
The post includes example screening and Python implementations, but the examples do not fully align: the code’s amplitude and limit-up calculations differ in detail from the written criteria, and its sample market data is limited to 2021. No backtest results, transaction costs, or risk-adjusted performance are supplied. The author notes that revenue alone can overlook profitability and cash flow, while rapid price moves and reliance on historical financial data can create risks. The rules are presented as an adjustable screening idea, not a validated trading system.
Key ideas
- The proposed screen combines price amplitude, recent limit-up frequency, and multi-year revenue growth.
- The post frames price activity as a proxy for trading interest and revenue expansion as a growth signal.
- It recommends adding market context and company factors when assessing candidates.
- The written rules and sample code differ in how some conditions are calculated.
- No backtest evidence is provided, and revenue growth does not capture profitability or cash flow.
